Construction & Design

The ARP Hex Bolt Kits feature a one-piece construction made from premium 8740 chromoly steel, a material renowned for its exceptional strength-to-weight ratio and durability. The heat treatment process enhances the tensile strength, ensuring the bolts can withstand high loads and stresses encountered during demanding automotive and marine operations. The black oxide finish not only provides corrosion resistance but also helps prevent galling and seizing during installation and removal. The flanged hex head design allows for maximum torque application with standard wrenches, reducing the risk of cam-out and damage to the fastener.

These bolts are engineered with precise threading and dimensions to ensure a perfect fit and reliable clamping force. Their robust construction and high-quality materials make them suitable for use in high-stress environments, providing long-lasting performance and peace of mind for your projects.

Installation & Fitment

The ARP Hex Bolt Kits are designed for straightforward, bolt-on installation. They utilize standard SAE 5/16˝-24 threads and feature a flanged hex head for easy tightening with common tools. No special tools or modifications are required for most applications. Proper torque specifications should be followed to ensure optimal clamping force and safety. These bolts are suitable for a wide range of automotive, marine, and trailer applications, making them a versatile choice for both professional mechanics and DIY enthusiasts.
