Threaded Nut Insert Steel 10pk

The ALLSTAR PERFORMANCE Threaded Nut Insert Steel 10-pack (SKU ALL18547-10) is a precision-engineered fastening component designed for applications requiring reliable threaded connections in high-vibration or high-stress environments. Each insert features a 1/4-20 inch internal diameter and 3/8 inch outer diameter, with a black oxide finish that resists corrosion and provides a professional appearance across automotive, machinery, and industrial assembly work.

Steel construction provides the rigidity and load-bearing capacity required for repetitive fastening cycles without thread stripping or pull-out failure. The 1/4-20 thread specification is among the most common fastening standards in automotive and light machinery applications, making these inserts widely compatible with standard hardware. Black oxide coating enhances corrosion resistance compared to bare steel, particularly in environments subject to moisture, salt spray, or temperature cycling. The 3/8 inch outer diameter accommodates standard hole sizes used in sheet metal, composite substrates, and cast aluminum components common to engine rebuilds, frame repair, and equipment restoration.

This 10-pack quantity is ideal for mechanics, fabricators, and technicians who perform regular assembly or repair work and need a cost-effective stock of replacement inserts. Users in automotive restoration, small engine service, and industrial maintenance benefit from having threaded nut inserts on hand to avoid downtime when existing fastening points become compromised. ALLSTAR PERFORMANCE is recognized in the aftermarket racing and automotive service sector for producing quality fasteners and assembly components, making this product a practical choice for professional shops and dedicated enthusiasts alike.
