Bolt 12pt 3/8-24 x 7/8

The Winters Bolt 12pt 3/8-24 x 7/8 is a precision fastener engineered for law enforcement, military, and professional tactical applications where reliability under stress is non-negotiable. This universal steel bolt serves as a critical replacement component for suppressor mounts, optic bases, rail systems, and modular weapon platform assemblies. When one fastener fails in the field, mission capability fails—this bolt ensures your critical gear stays secured under recoil, movement, and environmental extremes.

Featuring a 3/8-24 thread pitch and 7/8-inch length, this bolt accommodates standard tactical accessory mounting bosses and provides optimal engagement depth in suppressor adapters and picatinny rail hardware. The 12-point head design distributes clamping force across a wider surface area than traditional six-point fasteners, reducing stress concentration and galling—a critical advantage when working with anodized aluminum or hardcoat components common in AR platforms and precision rifle builds. Black oxide finish resists corrosion without adding thickness, ensuring zero tolerance stack-up issues. Constructed from hardened steel, this fastener maintains tensile strength across temperature extremes from desert operations to arctic environments.

Armorer technicians, weapons maintenance teams, and precision rifle competitors benefit most from stocking this universal fastener for immediate access during build-outs or field repairs. Compatibility spans suppressors with 3/8x24 mounting interfaces, optic mounting systems, KeyMod or M-Lok attachment solutions, and modular stock adapters. Installation requires only a properly-sized wrench or socket—the 12-point head accommodates standard 9/16-inch or metric equivalents common in military field kits. Keep a supply on hand for emergency repairs or preventative maintenance on mission-critical platforms.
