ARP 722-1000 Stainless 5/16-24 Thread 1.000″ UHL 6-Point Bolt Set of 5

Description

Product Overview

The ARP 722-1000 is engineered for the most demanding automotive performance environments. Constructed from high‑grade stainless steel, this bolt offers exceptional corrosion resistance while maintaining the tensile strength required for critical engine components. The 5/16-24 fine right‑hand thread provides a precise fit for high‑stress applications, and the 1.000″ UHL (Unified Length) ensures the bolt sits flush against the mating surface, eliminating gaps that could lead to fatigue over time.

Each bolt features a six‑point head that distributes torque evenly, reducing the risk of rounding off the fastener during installation. The 3/8″ socket allows for easy access with standard ratchet tools, speeding up assembly and service procedures. The set includes five identical bolts, each weighing 3.34 ounces, making it an ideal solution for batch installations or replacement of multiple fasteners in a single engine build.

Usage

Designed for high‑performance engines, the ARP 722-1000 bolt is suitable for a range of applications, including cylinder head assembly, intake manifold mounting, and transmission housing connections. Its fine thread pitch offers superior clamping force, which is essential for maintaining compression integrity under extreme temperature and pressure conditions.

Whether you are a professional mechanic, a race team technician, or an enthusiast building a custom powertrain, these bolts provide the confidence that critical joints will remain secure throughout the life of the vehicle. The stainless‑steel construction also makes them an excellent choice for marine or off‑road applications where exposure to salt and moisture is a concern.
