S/S Bolt Kit - 12pt. (5) 5/16-24 x 1.500

The ARP Stainless Steel Bolt Kit – 12pt, 5/16-24 x 1.500 (set of 5) delivers precision fasteners engineered for critical applications where corrosion resistance and consistent thread engagement are non-negotiable. ARP's stainless steel bolts are manufactured to exacting tolerances and polished to a mirror finish, making them ideal for firearm assembly, automotive builds, or any high-reliability fastening scenario where standard hardware falls short.

Each bolt in this five-piece kit features a 5/16-24 thread specification with a 1.500-inch length and a 12-point head geometry. The 12-point design distributes load across more contact surfaces than a 6-point head, reducing the risk of fastener rounding and improving removal reliability even after years of use. Stainless steel construction resists oxidation and corrosion in harsh environments—a critical advantage for components exposed to moisture, salt air, or temperature cycling. The polished finish enhances both appearance and corrosion resistance while allowing visual inspection for stress cracks or deformation.

This bolt kit serves operators, gunsmiths, and builders who demand repeatability and durability in firearm assembly. ARP fasteners are commonly specified in high-end custom builds where OEM hardware is upgraded for superior longevity. The 5/16-24 thread is a standard specification in many tactical platforms, making these bolts compatible across diverse assembly applications. Stocking this five-count kit ensures you have backup fasteners on hand without over-purchasing inventory.

ARP's commitment to precision manufacturing and material science positions these bolts in the upper tier of fastener reliability. Whether you're building a precision rifle, assembling critical machinery, or maintaining existing equipment, stainless steel ARP bolts provide the confidence that fastening won't be a point of failure.
