Fasteners for the Automotive Industry

South Coast Fasteners stocks the complete range of fasteners the automotive industry demands, from standard grades to metric hardware engineered for engine, chassis, and body applications.

Hex Cap Screws

Grade 8 hex cap screws deliver the tensile strength required for engine mounts, suspension components, and drivetrain connections where vibration and load are constant. Grade 5 hex cap screws handle general assembly, bracketry, and accessory mounting throughout the vehicle. Coarse and fine thread options match factory torque specifications for consistent, repeatable installation. Multiple finishes resist the corrosion encountered in under-hood and undercarriage environments.

Metric Bolts

Metric fasteners are standard across imported vehicles, OEM equipment, and modern domestic platforms built to international specifications. We stock metric bolts in coarse and fine pitch across a wide diameter range for engine assemblies, transmissions, and undercarriage work. Property class grades from 8.8 through 12.9 match the strength requirements of critical automotive connections. Consistent thread quality ensures proper torque-to-tension across high-volume assembly.

Flange Bolts

Flange bolts integrate a washer face that distributes clamp load and resists loosening under continuous vibration, making them a staple in exhaust systems, brackets, and body panel mounting. The serrated flange grips mating surfaces to maintain torque through thermal cycling and road vibration. This eliminates the need for a separate washer, reducing part count and speeding assembly. Available in multiple grades and corrosion-resistant finishes.

Socket Head Cap Screws

Socket head cap screws deliver high clamp force in tight, recessed locations common in engine, transmission, and performance assemblies. The internal hex drive allows high torque application where wrench clearance is limited. Alloy steel construction provides strong strength for precision automotive and machine work. Black oxide and plated finishes match the application environment.

Self-Tapping and Sheet Metal Screws

Self-tapping screws form mating threads in body panels, trim, and interior components without pre-tapping, speeding both assembly and repair. The hardened threads bite into thin gauge steel and aluminum while holding firm against vibration. A range of head styles and drive types accommodates visible and concealed fastening. Corrosion-resistant finishes protect against moisture and road salt exposure.

Machine Screws

Machine screws provide precise, repeatable fastening in electrical connections, sensor mounting, and control modules where consistent torque matters. Multiple drive types and thread pitches accommodate automotive assembly procedures and service protocols. Flat head styles sit flush in visible interior and trim applications. Available in steel and stainless for varied environmental exposure.

Hex Nuts and Lock Nuts

Nylon insert locknuts resist vibration-induced loosening in suspension, drivetrain, and chassis connections where fastener integrity is critical. The nylon collar maintains clamp force through constant road vibration and thermal cycling. We also stock standard hex nuts across grades and finishes for general automotive assembly. All-metal locknuts are available for high-temperature applications near exhaust and engine components.

Flange Nuts and Jam Nuts

Serrated flange nuts spread clamp load and lock against the mating surface, holding position through vibration without a separate washer. Hex jam nuts provide a thin profile for stacking, locking, and space-constrained fastening in suspension and linkage assemblies. Both styles speed assembly while maintaining secure engagement under load. Available in steel and corrosion-resistant finishes.

Flat Washers and Lock Washers

Flat washers distribute clamping loads and protect softer body panels and composite components from fastener embedding. Lock washers add spring tension that prevents loosening in high-vibration drivetrain and suspension assemblies. Both are available in finishes suited to under-hood and undercarriage corrosion exposure. Fender washers with oversized outer diameters spread load across thin sheet metal in body applications.

Blind Rivets

Blind rivets create permanent, vibration-resistant joints in body panels, trim, and interior structures where access is limited to one side. The mandrel-set design provides consistent clamp force across thin and dissimilar materials common in modern vehicle construction. Aluminum and steel bodies match the substrate for galvanic compatibility. Multiple grip ranges and head styles cover structural and cosmetic applications.

Hose Clamps

Hose clamps secure coolant lines, fuel lines, and air intake connections where leakage or disconnection would compromise vehicle performance. Worm gear and spring styles accommodate varied hose diameters across engine and cooling systems. Stainless construction resists corrosion from heat, fluids, and road exposure. Consistent clamping pressure maintains a sealed connection through thermal cycling.

Cotter Pins and Clips

Cotter pins, hairpin clips, and retaining clips secure castle nuts, clevis connections, and linkage components against rotation and walk-out. These low-cost fasteners provide positive mechanical locking in steering, suspension, and brake hardware. Stainless and plated finishes resist corrosion in exposed undercarriage locations. A range of sizes covers light linkage through heavy chassis hardware.

U-Bolts and Muffler Clamps

U-bolts and muffler clamps secure exhaust components, leaf spring assemblies, and round stock to frame members across the undercarriage. The U-shaped body wraps the component while threaded legs provide adjustable, high-strength clamping. Plated and stainless finishes resist the heat and corrosion of exhaust and suspension environments. A range of sizes fits common pipe, tubing, and spring dimensions.

Wheel Studs and Lug Hardware

Wheel studs, lug nuts, and related hub hardware carry the safety-critical loads of the wheel-to-hub connection. Hardened, precision-threaded components maintain consistent torque and clamp force through braking, cornering, and impact loads. Finishes resist the corrosion and heat of the wheel environment. Correct grade and thread matching is essential to safe assembly and service.

Threaded Rod

Threaded rod supports custom fabrication, equipment mounting, and shop fixturing in automotive manufacturing and repair facilities. Continuous threading allows field cut-to-length customization for brackets, jigs, and hardware. Available in multiple grades and diameters for light to heavy fabrication. Stainless options serve corrosion-prone shop and equipment applications.
