Bolt Kit - 12pt. (5) 3/8-24 x 1.750

The Bolt Kit - 12pt. (5) 3/8-24 x 1.750 by ARP is a premium fastening solution designed for high-performance engine builds and critical automotive applications. This kit is ideal for mechanics and engine builders who require reliable fasteners for assembling stroker motors, upgrading cylinder head hardware, or reinforcing suspension geometry.

Constructed from ARP's proprietary alloy steel, these hex-head fasteners feature 12-point heads that distribute load across a wider surface area, minimizing the risk of rounding or stripping during installation and removal. The 3/8-inch diameter with a 24-thread-per-inch pitch ensures optimal strength-to-weight ratios for various engine block applications, while the 1.750-inch length is suitable for standard boss depths in many popular platforms.

Engine builders working on performance applications, including turbo installations and nitrous systems, rely on ARP fasteners for their durability and reliability. Each kit contains five precision-manufactured bolts that are essential for preventing joint failure under peak combustion pressures or thermal cycling.
