Bolt Kit 12pt 5pk 10mm x 1.25 x 80mm

The ARP Bolt Kit 12pt 5pk 10mm x 1.25 x 80mm (SKU ARP673-1010) is a professional-grade fastener set designed for precision assembly and repair work across automotive, machinery, and equipment applications. This five-piece set features ARP-spec chromoly construction with black oxide finish, delivering the corrosion resistance and structural integrity demanded in high-stress environments where standard hardware fails.

Each bolt measures 10mm diameter with 1.25mm thread pitch and 80mm length, finished with a 12-point head design that provides superior contact distribution and reduces fastener stripping during installation and removal. The chromoly steel construction offers higher tensile strength than mild steel, critical for load-bearing applications. Included washers ensure proper load spreading and prevent bolt head seating issues in softer materials. Black oxide plating protects against surface oxidation while maintaining a professional appearance across industrial and field equipment.

Operators, maintenance technicians, and equipment specialists rely on ARP fastener kits for engine builds, transmission repairs, suspension assembly, and structural reinforcement where fastener reliability cannot be compromised. The 12-point head design is particularly valued in precision work where torque accuracy matters—the increased contact points distribute force more evenly than 6-point alternatives, reducing the risk of bolt deformation under repetitive stress or high-torque applications. The universal sizing makes this kit compatible across multiple platforms and assembly types.

ARP fasteners are manufactured to tight engineering tolerances and are a recognized standard in motorsports, industrial maintenance, and tactical equipment assembly environments where fastener failure creates operational risk or safety exposure.
