5/16-24 SS 12pt Nut Kit (10pk)

The 5/16-24 SS 12pt Nut Kit (10pk) from ARP delivers premium stainless steel fasteners engineered for applications requiring corrosion resistance and reliable mechanical performance. This ten-piece set is ideal for builders, machinists, and automotive enthusiasts who demand dependable hardware for critical assembly work. Whether you're restoring vintage equipment, assembling high-performance engines, or executing precision fabrication projects, these polished stainless nuts provide the durability and aesthetic finish that distinguishes professional-grade work.

Each nut features a 5/16-24 thread specification with a 12-point head design, maximizing tool engagement and reducing the risk of rounding during installation or removal. The stainless steel construction resists oxidation and corrosion in harsh environments—a critical advantage over zinc-plated alternatives when working in automotive, marine, or outdoor applications. The polished finish not only enhances appearance but also provides a protective oxide layer, ensuring long-term integrity. The 12-point configuration accommodates both standard wrenches and sockets, improving accessibility in tight spaces where traditional 6-point nuts prove inadequate.

This kit suits engine builders, suspension technicians, and anyone working with 5/16-24 threaded fastener systems where corrosion prevention is non-negotiable. The ten-piece quantity makes this set practical for single applications or small-batch production runs. ARP's reputation for precision fastening ensures these nuts meet tight tolerances, delivering secure, vibration-resistant connections that hold under dynamic loads. Keep a kit on hand for emergency replacements, restoration projects, or as part of a comprehensive fastener inventory.
