One failed fastener stops an entire high-volume production line. For original equipment manufacturers (OEMs), the fastener you specify drives both profit and reliability. Thin-gauge metals, composites, and plastics will not hold traditional tapped threads, yet engineers still need strong, reusable load-bearing threads in those materials. Production schedules keep running, and every downstream failure adds cost.
The financial stakes are real. According to McKinsey & Company, supply chain disruptions cost a manufacturer close to 45 percent of one year’s earnings (EBITDA) over the course of a decade. The American Society for Quality puts the cost of poor quality at 15 to 20 percent of sales revenue, covering rework, scrap, and warranty claims that often trace back to a single component. Sourcing engineered fasteners like Sherex rivet nuts through a qualified partner removes that risk with spec-compliant parts and a secure supply chain.
What Sherex Rivet Nuts Do in Modern Manufacturing
A rivet nut is a one-piece, internally threaded fastener installed from a single side of a workpiece. That “blind” installation creates a strong, permanent, reusable thread in thin or brittle materials where a tapped hole would fail. Sherex Fastening Solutions leads this category through precision engineering, material science, and a deep range of styles built for specific applications.
Unlike standard hardware, Sherex rivet nuts solve targeted joining problems. People often compare them to clinch nuts, PEM nuts, or the commonly searched term “nutserts,” but the installation method sets them apart. Clinch nuts need a press and access to both sides of the material. Rivet nuts install blind with a spin-pull or spin-spin tool, which makes them ideal for tubing, extrusions, and other closed profiles in automotive, aerospace, and electronics work.
Common Production Challenges Engineered Fasteners Solve
Specifying the right fastener early in design prevents expensive problems later. Generic nuts and bolts or poorly specified parts build weakness into an assembly, and that weakness shows up in production or out in the field.
Engineered rivet nuts address several recurring challenges:
- Thread stripping in thin materials: Tapping threads into sheet metal thinner than the fastener diameter leaves too little thread engagement, and the threads strip under torque. A rivet nut forms a deep threaded barrel that spreads the load across a wider surface.
- No backside access: Sealed enclosures and structural tubing leave no way to hold a nut behind the panel. Rivet nuts fasten blind from one side and speed up final assembly.
- Costly secondary operations: Welding nuts to a frame is slow, expensive, and hot enough to scorch surface finishes. Rivet nuts cut those steps, lower labor costs, and raise throughput.
- Material incompatibility: Joining dissimilar metals invites galvanic corrosion. Sherex offers matching materials and platings that keep the joint compatible and stop long-term degradation.
- Spin-out under high torque: Round-bodied inserts can spin in the hole when a bolt tightens. Full and semi-hexagonal Sherex bodies lock into the hole and resist spin-out.
- Installation inconsistency: Hand installation varies by operator, shift, and tool wear, which produces uneven clamp loads and unpredictable joint quality. Calibrated spin-pull tooling sets a repeatable stroke so every installation matches the last.
- Post-installation failure: Beyond spin-out, an under-set or over-set rivet nut can pull out, push out, or torque out in service. Correct grip range, hole size, and installation force keep the threaded barrel locked under load.
Sherex Rivet Nut Materials
Material choice drives strength, corrosion resistance, and compatibility with the parent part. Sherex covers a full range to match almost any industrial environment.
Steel Rivet Nuts
Steel is the most common rivet nut material, and it delivers strong performance at a low cost. Sherex makes them from low-carbon steel such as 1008 or 1010 for general industrial, automotive, and appliance work. Steel rivet nuts almost always carry a plating to stop oxidation. A zinc finish with trivalent chromate is the standard and protects parts in interior or non-critical exterior service.
Stainless Steel Rivet Nuts
When corrosion resistance matters, stainless steel wins. Sherex offers A2/304 and A4/316 grades. A2 handles many environments well. A4 adds molybdenum and stands up to chlorides and acids, which makes it the choice for marine, medical, chemical processing, and food-grade equipment.
Aluminum Rivet Nuts
When weight drives the design, aluminum rivet nuts answer. Aerospace, electric vehicle, and consumer electronics teams use them to cut product weight while holding joint integrity. Aluminum fasteners also pair with aluminum parent materials to prevent the galvanic corrosion a steel fastener would cause.
Sherex Rivet Nut Sizes and Styles
Picking the right rivet nut takes more than a thread size. Head style, body shape, and grip range all decide whether the installation holds.
- Head style: The common options are flat head (large flange), low-profile head, and countersunk head. A flat head gives the largest load-bearing surface. A countersunk head sits flush, which matters for aerodynamics or appearance.
- Body shape: A smooth round body suits many jobs. For higher torque, a hexagonal or semi-hexagonal body locks into a matching hex hole and stops the nut from spinning.
- Grip range: Every rivet nut lists a grip range, the material thickness it is built to clamp. Install outside that range and the joint fails. Measure the parent material accurately before you choose the part.
- Specialty designs: Sherex also builds the PLUSNUT®, a slotted-body fastener for soft or brittle materials like plastic, composite, and fiberglass. During installation the slots expand into large folding legs on the blind side, spreading the load wide to prevent cracking or pull-through.
How Rivet Nuts Install
Installing a Sherex rivet nut is a fast, repeatable mechanical process that needs no specialized labor. That simplicity beats welding on every count.
The steps run as follows:
- Prepare the hole: A precise hole is critical. Use the manufacturer-specified rivet nut drill size to drill or punch the hole. An incorrect hole diameter is a primary cause of installation failure.
- Thread the rivet nut: Spin the rivet nut onto the mandrel of the installation tool.
- Insert into the workpiece: Seat the rivet nut in the hole until the flange rests firmly against the surface.
- Actuate the tool: Trigger the tool. It pulls the mandrel back, collapses the unthreaded shank, and forms a bulge on the blind side that clamps the material between flange and bulge.
- Remove the tool: Once the bulge sets, the mandrel unthreads from the rivet nut and leaves a permanent thread ready for a bolt or screw.
Clinch nuts work differently. They need a press to squeeze the fastener into the sheet metal and displace material to hold. Blind installation gives rivet nuts design freedom that press-in fasteners cannot match.
Sourcing Sherex Rivet Nuts in Bulk for Production Lines
For OEMs, sourcing matters as much as engineering. A stockout of one rivet nut can idle a full assembly line, so supply continuity is as critical as the part spec. Partner with an authorized distributor like Component Solutions Group for your Sherex rivet nuts and procurement becomes a strategic advantage instead of a transaction. As an AS9120 and ISO 9001:2015 certified partner, we deliver supply chain certainty, not just parts.
Bulk sourcing through CSG gives you several advantages:
- Vendor-managed inventory (VMI): We hold the right stock at the point of use, cut your on-hand inventory costs, and keep the line running.
- Global sourcing, local support: As part of the global Bufab Group, we command the sourcing power and logistics to keep supply steady through volatile markets. Our engineering support stays local and hands-on.

Installation Tooling for Sherex Rivet Nuts
A clean installation demands the right tool. The wrong tool under-installs or over-torques the rivet nut and weakens the joint. Component Solutions Group supplies the full range of Sherex-approved fastener installation tooling for any production volume.
- Hand tools: Manual tools fit field repairs, prototyping, and low-volume assembly. They stay light, portable, and simple to run.
- Pneumatic and hydraulic tools: Production lines need air or hydraulic power for speed and consistency. These tools run spin-pull or pull-to-stroke settings so every installation matches the last.
- Automated systems: For the highest volumes, CSG specs fully automated or robotic installation systems. They feed and install rivet nuts at high speed with no operator, which maximizes throughput and quality control.
- Calibration and maintenance: Installation tools drift over time. CSG supports calibration, spare parts, and replacement so your tooling holds spec across its service life.
How to Move From Recurring Failures to Predictable Performance
Trading reactive failure fixes for engineered performance comes down to two decisions: pick the right component for the application, and pick the right partner to keep it in stock. A generic or poorly specified fastener hides its cost until it surfaces as production delays, rework, warranty claims, and damage to your reputation for quality.
Bring an expert partner in early and you lock in the fastening solution that meets your mechanical, environmental, and assembly requirements. That work weighs materials, head styles, grip ranges, and the tooling each one needs for repeatable results. A strategic sourcing partner does more than fill purchase orders. They bring engineering expertise, manage inventory to de-risk your supply chain, and deliver the traceability that aerospace and automotive programs demand.
Predictable performance means treating C-class components with A-class importance. An engineered fastener like a Sherex rivet nut, backed by a strong supply chain program, is a direct investment in product reliability and your bottom line.

Frequently Asked Questions (FAQs)
What is the difference between a rivet nut and a nutsert?
In practice, none. “Nutsert” is a widely used name for the same blind-installed, internally threaded fastener that engineers call a rivet nut. Sherex and most catalogs list the part as a rivet nut, so either term lands you on the same component.
What’s the difference between a rivet nut and a clinch nut (like a PEM nut)?
Installation method. A rivet nut installs blind from one side, using a tool that pulls a mandrel to form a bulge. A clinch nut, such as a PEM nut, presses into the sheet metal and needs access to both sides plus a press.
How do I choose the right size and grip range for a rivet nut?
Start with the thread size of the bolt you plan to use. Then measure the total thickness of the material you are fastening into. Pick a rivet nut whose grip range covers that thickness. Step outside the grip range and the installation fails.
Can Sherex rivet nuts be used in plastic or composite materials?
Yes. For plastics, fiberglass, and composites, reach for the Sherex PLUSNUT®. Its slotted body forms large folding legs on the blind side during installation, spreading clamping force across a wide area to prevent cracking or pull-through.
How does CSG ensure quality and traceability for bulk Sherex orders?
