Oval Allen Hd Fasteners 7/16 .550in 10pk Steel

The Oval Allen HD Fasteners 7/16 x .550in from Allstar Performance are precision-engineered fastening solutions built for serious automotive builders and mechanics tackling high-performance engine swaps, custom chassis fabrication, and transmission work. These Grade 8 steel hex socket cap screws provide the clamping force and reliability needed in applications where standard fasteners fall short. Whether you're assembling a fuel system, securing an intake manifold, or fastening critical drivetrain components, this 10-pack delivers the dependability expected in professional-grade motorsports and restoration projects.

Manufactured from hardened steel, these hex socket cap screws feature a robust 7/16-inch diameter with a .550-inch head height, offering superior load distribution and resistance to vibration loosening compared to slotted or Phillips-head alternatives. The oval-head design provides excellent contact surface area and distributes clamping pressure evenly across gaskets and sealing surfaces, critical when working with aluminum engine blocks or precision-machined housings. Allstar Performance's strict material specifications ensure consistent hardness and thread integrity across every fastener, eliminating the variables that plague budget fastener packs and protecting your investment in custom fabrication work.

This fastener pack is ideal for engine builders, transmission technicians, and fabricators working on LSx swaps, LS stroker builds, and fuel system installations where precision and repeatability matter. The 10-pack quantity makes it perfect for staging bolts on a work bench during assembly or stocking your garage kit for multiple projects. Ensure proper torque specifications are followed during installation—these hardened fasteners require a quality hex socket driver to prevent rounding and deliver the clamping force your engine build demands.
