Hex Bolt Kit M8 x 1.25 x 30mm

The ARP Hex Bolt Kit, model 661-1003, offers premium-quality fasteners for a wide range of applications on cars, boats, and trailers. Each bolt is constructed from specially heat-treated 8740 chromoly material and finished with a durable black oxide coating. These fasteners are engineered to provide a substantial extra margin of safety, boasting a nominal tensile strength of 180,000 psi, exceeding that of standard Grade 8 hardware. This kit includes five bolts, each featuring an M8 x 1.25 metric thread size and a 30.00mm underhead length. The flanged hex head requires a 10mm wrench for installation, and necessary washers are included for a complete assembly. The robust construction and high tensile strength make these bolts ideal for applications where reliability and strength are paramount. While the product page does not specify any particular vehicle applications, it is suitable for use across many automotive, marine, and recreational vehicle projects. Each kit comes with a manufacturer's standard warranty, ensuring peace of mind for the end-user.
