8mm x 1.25 x 50mm 6pt Bolt Kit (5pk)

The 8mm x 1.25 x 50mm 6pt Bolt Kit (5pk) by ARP is a precision fastener solution engineered for high-performance engine builds and critical mechanical assemblies. Designed for users who demand reliability in motorsports, competition shooting platforms, and tactical equipment maintenance, this bolt kit delivers the dimensional consistency and tensile strength required in demanding applications. Whether you're assembling a competition engine, rebuilding firearm components, or working on precision machinery, ARP's reputation for quality fastening solutions makes this 5-pack an essential addition to your technical toolkit.

These metric bolts feature an 8mm diameter with a 1.25mm pitch thread specification and a 50mm length, making them suitable for engine block work, head fastening, and structural assemblies where precise thread engagement and clamping force are non-negotiable. The 6-point socket design provides superior contact geometry compared to 12-point alternatives, reducing the risk of fastener rounding and ensuring reliable torque application even under high-load cycling. ARP's controlled-head bolts are manufactured to exacting tolerances and feature enhanced tensile properties, critical for applications experiencing vibration, thermal cycling, or sustained pressure variations typical in motorsport and precision tactical platforms.

Mechanics, engine builders, and technical professionals working on late-model performance engines and precision assemblies will find this 5-pack ideal for critical fastening tasks. The compact package (0.32 lbs, 3.85 x 0.6 x 5.9 inches) fits easily into tool bags and work kits. Proper identification of your specific assembly requirements and correct torque sequencing according to manufacturer specifications ensure optimal clamping load and system reliability. ARP bolts are compatible with standard metric threading and 6-point socket driver sizes, making installation straightforward for anyone with basic mechanical training.
