Weld Nut 3/8-16 12pk

The Weld Nut 3/8-16 12pk from Coleman Racing Products is an essential fastening component for fabricators, race car builders, and automotive enthusiasts performing welded assembly work. These threaded inserts are designed to be welded directly onto metal surfaces, creating a permanent, load-rated threaded hole without the need for traditional bolt-through assembly. Whether you're building a custom roll cage, fabricating exhaust systems, or installing aftermarket components on a racing platform, this 12-pack provides the quantity needed for medium-scale projects while maintaining consistent quality across all fastening points.

Each weld nut features a 3/8-16 thread specification, meaning 3/8-inch diameter with 16 threads per inch—a standard metric in automotive and mechanical applications that accepts common 3/8-16 bolts and studs. The design incorporates a welding base that distributes heat evenly during the fusion process, ensuring a strong, structurally sound joint between the nut and parent material. Coleman Racing Products manufactures these components to precision tolerances, critical for high-vibration environments like engine bays, suspension systems, and chassis work where fastener failure poses safety risks. The welded configuration eliminates the possibility of fasteners backing out under stress, vibration, or thermal cycling—a major advantage over conventional bolt-and-nut assemblies in performance automotive applications.

This 12-pack is ideal for welding shops, race teams, and serious DIY fabricators tackling multi-point installations on custom frames, brackets, or subframes. The compact shipping weight of 0.53 lbs reflects the material efficiency of the design—pure fastening functionality without excess bulk. Installation requires basic MIG or TIG welding equipment and proper metallurgical practice; ensure base metal compatibility and appropriate heat input for your material gauge. These weld nuts work best on steel and steel-alloy substrates common in automotive fabrication, delivering permanent, vibration-resistant joints suitable for street and competition vehicles alike.
