This is the 1/2 inch version of the tactical mounting system that we use with our ammo clips and other sheath/holster loops and mounts. The 1/2 inch washer allows for additional clearance, needed on thicker items.
The mounting assembly comes with:
(1) Threaded Stud - Black Coated (.500" Length)
(1) Phillips Head Screw - Black Coated
(1) "Sound Silencing" flex bushing (.500" Length)
