Bolt w/End Cap 7/16in x 5.0in

The Jones Racing Products Bolt with End Cap 7/16in x 5.0in (part number BEC-2109-C) is a precision mandrel drive bolt engineered for high-performance mechanical and racing applications. This 7/16-inch bolt features a 5-inch length with a hex head and integral step washer, designed to deliver reliable fastening under demanding rotational and load-bearing conditions. Built from steel, this single-unit fastener provides the structural integrity and dimensional consistency critical to racing platforms, engine assemblies, and precision mechanical systems requiring exact bolt geometry and secure retention.

The 7/16-inch diameter and 5-inch length combination positions this bolt for mid-range fastening applications where standard automotive or industrial fasteners may fall short. The integrated step washer distributes clamping force across a wider bearing surface, reducing the risk of head pull-through and improving joint security under vibration. The hex head design accommodates standard wrench and socket engagement, simplifying installation and removal in tight engine bays or assembly fixtures. Steel construction provides both cost-effectiveness and proven fatigue resistance across repeated thermal and mechanical cycling, a critical requirement in racing environments where bolt failure can result in catastrophic component loss.

This fastener is specified for professionals and enthusiasts working on high-performance engines, transmission systems, differential assemblies, and chassis components where mandrel-drive precision and repeatable torque characteristics are non-negotiable. Racing teams, engine builders, and powersports mechanics rely on Jones Racing Products fastening components to maintain the exact specifications demanded by competition rules and performance tuning protocols. At 0.28 lbs per unit, this bolt integrates into builds without adding unnecessary weight while maintaining the strength-to-weight ratio essential in weight-sensitive racing platforms.

Jones Racing Products has established market credibility in the aftermarket racing and performance sector, where precision fastening is as critical as engine tuning. This bolt represents the engineering standard for builders who cannot afford fastener failure during competition or high-stress operation. Whether you're assembling a race engine, upgrading a differential, or restoring a performance vehicle to exact specifications, this 7/16in x 5.0in mandrel drive bolt delivers the dimensional accuracy and structural reliability that separates professional-grade assembly from conventional fastening solutions.
