3/8-24 Dr. Retaining Bol

The 3/8-24 Dr. Retaining Bolt is an essential fastening component for precision tool assemblies and automotive applications where reliable retention under load is non-negotiable. As a mechanic who works with impact tools, air-driven sockets, and drive assemblies, you'll recognize this as a critical safety component that prevents socket or attachment separation during high-torque operations. Whether you're running a shop, building custom engine bay setups, or maintaining industrial pneumatic tools, this retaining bolt ensures your drive components stay secured under demanding conditions.

The 3/8-inch drive size matches standard socket sets and impact tool interfaces, while the 24 TPI (threads per inch) thread specification provides fine-pitch engagement for controlled clamping force without over-tightening. At just 0.05 lbs, this lightweight fastener minimizes tool weight while delivering the mechanical advantage needed to lock drive interfaces securely. The compact dimensions (2.3 x 0.65 x 2.9 inches) allow installation in tight engine compartments and confined tool heads, making it ideal for both OEM specifications and aftermarket modifications where space is limited and precision matters.

Technicians working with air impact wrenches, socket adapters, and pneumatic drive systems will find this retaining bolt indispensable for maintaining tool integrity during repetitive high-torque cycling. It's compatible with standard 3/8-inch drive tool ecosystems, making replacement or bulk ordering straightforward for shop environments. Keep extras on hand—a missing or stripped retaining bolt can leave you sidelined mid-job, and having stock available ensures continuity across your tool maintenance schedule and custom automotive builds.
