The Yankee Hill Machine sRx Black Thread Protector is a precision-machined dust cap designed to safeguard the threads on your sRx suppressor mounts when your can is off the rifle. If you're running YHM's sRx system or any suppressor with a 1 3/8" thread pitch, this simple accessory prevents dirt, debris, and accidental dings from compromising the integrity of your mounting threads—a small detail that pays real dividends in the field and at the range.
Built from 4140 chrome moly steel and finished in black oxide, the thread protector is built to handle rough use. At less than half an ounce and just over half an inch long, it's lightweight enough to pocket or stash in your gear without thinking about it. Precision machining means it fits snugly on your sRx threads without wobbling or binding.
Whether you're swapping suppressors between rifles, cleaning your can, or simply storing your gear between hunts, this protector keeps your threads clean and ready for the next shot. It's one of those unglamorous but genuinely useful pieces of kit that experienced shooters keep in their range bag or gun case.
| Material | 4140 Chrome Moly Steel |
| Finish | Black Oxide |
| Weight | 0.448 oz |
| Length | 0.5625" |
| Diameter | 1" |
| Thread Pitch | 1 3/8" |
The sRx Black Thread Protector is designed for the YHM sRx system and fits any suppressor with a 1 3/8" thread pitch. Check your suppressor's documentation or thread size before purchasing.
You receive one thread protector cap. It is designed to cap the male threads on your sRx mount when your suppressor is removed.
Thread protectors keep the precision-cut threads on your suppressor mounts clean and free from damage when your can is off the rifle. Dirt, dust, and minor impacts can compromise thread integrity, leading to loose fits or installation problems. A simple cap prevents those headaches.
The snug, precision-machined fit is designed to stay seated on your threads without excess play, though we recommend storing it in your range bag alongside your suppressor when not in use.
