S/S Stud Kit - (4) M8 x 1.25in x 51mm

The ARP S/S Stud Kit featuring (4) M8 x 1.25in x 51mm fasteners is engineered for demanding applications where reliable, corrosion-resistant fastening is non-negotiable. This stainless steel stud kit is ideal for motorsports enthusiasts, engine builders, and mechanical professionals who require high-strength threaded studs for critical assembly work. Whether securing cylinder heads, manifolds, or other precision engine components, these polished stainless studs deliver the dependability that ARP is known for across the automotive and industrial sectors.

Manufactured from premium stainless steel and finished to a polished surface, the ARP S/S Stud Kit resists corrosion and oxidation in harsh environments where standard carbon steel would degrade. Each stud measures M8 x 1.25 millimeter pitch thread with a 51mm overall length, designed to mate precisely with 12-point nuts included in the set for maximum contact area and load distribution. The 1.25mm thread pitch ensures fine-threaded engagement, critical for applications requiring precise clamping loads and vibration resistance in high-performance engine assemblies.

This universal four-piece stud kit suits custom engine builds, head gasket upgrades, and restoration projects where OEM fasteners fall short. The combination of stainless material and polished finish makes these studs visible-friendly for show engines while maintaining structural integrity. Installation is straightforward: thread studs into prepared holes, apply appropriate torque specifications per your engine builder's recommendations, and secure with the included 12-point nuts for reliable, repeatable clamping force that lasts.
