15 sold in last 24 hours
- FITS 5/8x24 THREADS - Also listed as 5/8-24 or 0.625x24. Sets the seating position of a muzzle brake or flash hider against the shoulder without over tightening.
- FIVE THICKNESSES, 20 WASHERS - Four each of 0.004, 0.008, 0.012, 0.020 and 0.040 in. Combine thicknesses to reach the exact stack height your assembly needs.
- STAINLESS STEEL, REUSABLE - Does not deform under torque, so the same washers can be removed and refitted while holding the same torque value.
- PRECISION CUT AND DEBURRED - Uniform thickness across the face and clean edges, so the mating part seats flat rather than cocking to one side.
- ALTERNATIVE TO A CRUSH WASHER - A crush washer compresses once. These do not, so the seating position is repeatable every time.
