1/2x28 Crush Washer for .223 5.56, 5 Pack, Black Oxide Steel
14 sold in last 24 hours
- FITS 1/2x28 THREADS - Also listed as 1/2-28 or 0.5x28. Check your thread pitch before ordering, as 1/2x28 and 5/8x24 are not interchangeable.
- CONICAL CRUSH DESIGN - The tapered face compresses as you torque, taking up the gap and seating a muzzle brake or flash hider square against the shoulder.
- SINGLE USE - A crush washer deforms permanently under torque. That deformation is what holds the position, and it is why the washer is renewed each time.
- FIVE PER PACK - Five washers in one pack, so you have one on hand whenever the mating part comes off and goes back on.
- BLACK OXIDE STEEL - Corrosion resistant finish, uniform thickness across the face and deburred edges, so the part seats flat rather than cocking to one side.

Estimated shipping
Select a product to estimate shipping.A crush washer holds a threaded part where you set it. This 5-pack covers 1/2x28 threads, also written 1/2-28 or 0.5x28.
How it works
The washer sits between the shoulder and the mating part. Its conical face compresses as you torque, taking up the gap and seating the part square at the position you chose. No thread locker, no guesswork about how far to turn.
Fits
Any 1/2x28 thread. Seats a muzzle brake or flash hider against the shoulder. Check your thread pitch before ordering, as 1/2x28 and 5/8x24 are not interchangeable.
Single use by design
A crush washer deforms permanently under torque. That deformation is what creates the hold, and it is also why the washer is renewed whenever the part comes off. Five per pack means you are not stopped waiting on a part.
Material and finish
Steel with a black oxide finish that resists corrosion. Uniform thickness across the face and deburred edges, so the part seats flat against the shoulder rather than cocking to one side.
If you remove the part often
A crush washer is the right choice for a permanent install. If you need a repeatable torque value or expect to refit the same part, stainless shim washers do the same job without deforming.
