Yankee Hill Machine 9mm Thread Protector 1/2x28 .570 OD – Pistol Barrels

This YHM thread protector safeguards your 9mm pistol barrel's threaded muzzle from damage, debris, and cross-threading when no muzzle device is installed. The .570-inch outer diameter provides a clean, flush profile on most factory 9mm pistol barrels while protecting the 1/2x28 threads from impact and corrosion during storage or carry.

Machined from steel with a black oxide finish, this thread protector installs hand-tight and should be checked periodically to ensure it remains secure. Compatible with any 9mm pistol barrel featuring 1/2x28 threading. Remove before installing compensators, brakes, or suppressors.
