YHM 9mm Pist Thread Protector 1/2x28 .570 Od

The YHM 9mm Pistol Thread Protector 1/2x28 .570 OD from Yankee Hill Machine Co is a precision-engineered steel component designed to protect your threaded pistol barrel when running without a suppressor, compensator, or other muzzle device. This straightforward defensive accessory preserves barrel threads from dust, debris, and environmental contamination that can compromise suppressor fit and sealing when you need it most.

Machined to exacting tolerances, the protector features a 1/2x28 thread pitch—the standard configuration for most modern 9mm pistols—with a .570 outer diameter that allows it to mount flush without interfering with holster draw or grip. The compact 2-inch length and 0.06-pound weight add virtually nothing to your carry configuration, making it an essential piece of preventive maintenance equipment. Steel construction provides durability against impact and corrosion without the weight penalty of larger muzzle devices.

This protector is built for operators and law enforcement who rotate suppressors across platforms or maintain threaded pistol barrels as primary equipment. Whether you're running a dedicated suppressed build, a range gun, or duty pistol with future suppressor capability, thread protectors prevent the expensive and time-consuming damage that forces barrel re-threading or replacement. Yankee Hill Machine has established a reputation for precision manufacturing and reliability in the tactical component space, making this a dependable choice for serious users who understand that small details matter in equipment maintenance.

For 9mm pistol owners with threaded barrels, a thread protector is standard-issue insurance. Keep your barrel threads in original condition so suppressors, brakes, and flash hiders seat properly when needed. Lightweight, simple, and effective—the kind of product that works best when you never have to think about it.
