Product Overview

The ARP 300-8246 hex bolt is engineered for high‑performance automotive environments where reliability and precision are paramount. Constructed from premium alloy steel, the bolt offers exceptional tensile strength while the machined black chrome finish provides both aesthetic appeal and superior corrosion resistance. The 7/16 inch thread is fully threaded, ensuring a consistent grip along the entire length of the fastener. Each package contains sixteen meticulously inspected bolts, each meeting ARP’s stringent quality standards. The hex head design allows for straightforward installation with standard tools, reducing assembly time and minimizing the risk of rounding off the fastener. This product is a direct replacement for OEM specifications, making it an ideal upgrade for enthusiasts seeking enhanced durability without compromising fitment.

Usage

These hex bolts excel in a variety of automotive applications, most notably in rocker arm assemblies where precise torque and secure fastening are critical. The fully threaded design distributes load evenly, reducing stress concentrations that can lead to premature failure. In addition to rocker arms, the bolts are suitable for engine mounting brackets, transmission housings, and performance‑oriented bolt‑on modifications. Their robust construction makes them reliable for both street and track use, handling the increased vibration and thermal cycling associated with high‑output engines. Installation is straightforward: apply the appropriate torque using a calibrated wrench, ensuring the bolt seats flush against the mating surface. The black chrome finish also makes the bolt an attractive visual component for exposed engine bays, complementing other performance parts.
