One Fastener Partner for Every Manufacturing Challenge.

CSG distributes a broad range of industrial fasteners including hex bolts, cap screws, machine screws, nuts, washers, self-clinching fasteners, blind rivets, rivet nuts, threaded inserts and custom or engineered C-parts. Product selection depends on the application, material, finish, strength and documentation requirements.

CSG is ISO 9001:2015 certified and maintains full lot traceability across its distribution operations. Additional documentation, material certifications or inspection requirements can be coordinated based on the specific needs of the customer program.

Supplier consolidation involves replacing multiple fastener and C-part vendors with a single sourcing partner. CSG can take over sourcing for standard, specialty and custom components, reducing the number of purchase orders, shipments, invoices and quality touchpoints while improving pricing through volume leverage.

Yes. CSG supports consignment inventory, kitting, custom packaging, forecasting and replenishment strategies designed around ongoing production consumption. Kanban and bin-level programs are available depending on the application and volume requirements.

Yes. In addition to standard catalog items, CSG can source custom and engineered C-parts through its global supplier network. This includes special materials, finishes, dimensions, head styles, threads, formed parts, machined components and other application-specific hardware based on drawing or specification.

Common materials include carbon steel in various grades, alloy steel, stainless steel (300 and 400 series), brass, aluminum and specialty alloys. Material selection should be based on the application’s strength, corrosion, temperature and environmental requirements. CSG can help identify the right material for the application.

Helpful information includes part number or drawing, dimensions, material, finish, quantity, annual usage, required specification, documentation requirements and target delivery timing. If you do not have every detail, CSG can start with the information available and help identify what else is needed. Contact CSG to speak with a Solutionist.

Automated assembly needs fasteners with tight dimensional consistency, repeatable drive torque and head shapes that feeders and vision systems handle reliably. Features such as self-locating chamfers and anti-cross-threading points prevent jams and misfeeds. CSG supplies automation-ready hardware, including torque-limited screws, self-clinching nuts, thread-forming screws and press-in studs for pneumatic drivers, electric torque tools and robotic end-effectors.

PEM is a brand of self-clinching fastener, and many engineers use the name for any clinch nut, stud or standoff pressed permanently into sheet metal. The fastener locks into a punched or drilled hole and gives strong, reusable threads without welding or tapping. CSG stocks PEM and Bossard self-clinching hardware in steel, stainless steel, aluminum and brass.

A Belleville washer is a cone-shaped spring washer that keeps tension on a bolted joint as it settles, wears or expands and contracts with heat. Stacked or used alone, it holds clamp load that a flat washer would lose, which reduces loosening and fatigue. CSG supplies Belleville, flat, split lock and spring washers in steel, stainless steel and other materials.

Use fasteners designed for the softer material: thread-forming screws with controlled torque, heat-set, ultrasonic or press-in threaded inserts, and torque-limited screws that cannot overload the part. Shoulder bolts and spacers absorb thermal expansion differences, and wide washers spread clamp load. CSG supplies these mixed-material options, including PLASTITE and POWERLOK thread-forming screws, with application recommendations from its engineering team.

Security fasteners stop unauthorized people from opening a product, using drive patterns that need a special tool. They protect consumer products, medical devices and safety-critical equipment, and they support warranty protection. CSG stocks pin-in-hex bolts, spanner, snake-eye, one-way and Torx security hardware, and can supply matching installation tooling for authorized service teams.

Food processing equipment usually uses 300 series stainless steel fasteners because they resist corrosion from washdown, cleaning chemicals and moisture. Smooth, low-profile heads are often chosen because they leave fewer places for residue to collect. CSG can source stainless bolts, screws, nuts and washers in standard and custom configurations, matched to the cleaning regime and the equipment builder’s specification.

Prevailing-torque lock nuts, serrated flange bolts, wedge-locking washers and removable-strength threadlocker all resist vibration while still allowing disassembly. Captive screws and quarter-turn fasteners suit panels that are opened often. Choose by joint design, vibration level and how often technicians need access. CSG can review the joint and recommend a locking method that holds in service without slowing maintenance.

Yes. Beyond fasteners, CSG supplies M12 and M8 industrial connectors with IP67 and IP68 rated housings, DIN rail brackets and spring terminals, cable management clips and bushings, panel-mount indicators and fuse holders, and leveling pads and vibration dampers. Buying these alongside bolts and screws keeps panel building and machine assembly on one purchase order and one supplier.

Yes. Through the Bufab Group’s sustainability capabilities, CSG supplies C-parts with verified emissions data, supplier sustainability audits and support for CBAM compliance. Steelcase used this to align its C-parts supply chain with a net-zero 2050 commitment. If your company reports supply chain emissions, ask for the data requirement at the quoting stage.
