Ball 5/16in Diameter Steel

The Ball 5/16in Diameter Steel detent ball is a precision mechanical component engineered for use in valve assemblies, detent mechanisms, and spring-loaded locking systems across industrial and tactical equipment. Built by WINTERS, a trusted manufacturer of quality precision parts, this detent ball serves as a critical engagement point in systems requiring controlled positioning and positive lock-and-release action. Whether used in firearm triggers, equipment latches, or hydraulic valve assemblies, this component ensures reliable repeatability and positive mechanical feedback in demanding applications.

Manufactured from steel, the Ball 5/16in Diameter Steel offers excellent hardness and compressive strength, making it ideal for high-cycle applications where wear resistance is critical. The 5/16-inch diameter is precision-engineered to fit standard detent spring assemblies and indexing mechanisms without binding or excessive play. Steel construction provides superior corrosion resistance compared to softer materials when properly maintained, and the smooth spherical geometry ensures uniform contact pressure and consistent mechanical response across thousands of operating cycles. The minimal weight of 0.01 lbs makes this component suitable for applications where mass sensitivity matters, from precision triggers to compact valve systems.

Tactical and firearms specialists, equipment manufacturers, and maintenance technicians rely on precision detent balls to restore or upgrade trigger mechanisms, safety systems, and locking assemblies. This component is commonly used in firearm trigger groups, select-fire mechanisms, and equipment latches requiring indexed positioning. Installation typically involves seating the ball into a spring-loaded detent hole where it interfaces with a mating surface to create positive mechanical lock. Individual unit packaging allows for replacement of worn detent balls or stocking for OEM repairs and custom builds. Verify bore diameter and spring tension specifications before installation to ensure proper fit and function.
