Weld On Nuts 3/8-16 Short 25pk

The ALLSTAR PERFORMANCE Weld On Nuts 3/8-16 Short 25-pack (SKU ALL18549-25) provides a reliable fastening solution for welded assembly applications where permanent mounting is required. These 3/8-16 thread weld-on nuts feature a 3/4-inch outside diameter mounting hole and are manufactured from steel in natural finish, designed for structural integrity in high-vibration and load-bearing environments. The 25-piece quantity makes this pack suitable for production runs, fabrication shops, and restoration projects requiring consistent batch fastening.

Each weld-on nut is engineered to accept a 3/8-16 male fastener, with the mounting hole diameter specified at 3/4 inch to accommodate standard welding fixtures and jigs. The short profile minimizes material waste while maintaining full thread engagement depth for secure fastening. Steel construction provides excellent heat resistance during welding operations and resists corrosion when properly finished, making these nuts suitable for both indoor fabrication and external assembly work. The natural steel finish allows for paint, powder coating, or plating after installation if additional corrosion protection is needed.

This 25-pack is ideal for automotive restoration, trailer manufacturing, frame fabrication, machinery assembly, and any application requiring field-weldable nuts with consistent thread specifications. Fabricators and welders favor weld-on nuts over through-bolts when structural access is limited or when permanent installation without fastener protrusion is required. The 3/8-16 thread size balances load capacity with ease of welding, making it a popular choice for mid-range fastening tasks across industrial, agricultural, and motorsports fabrication.
