Built for precision fit and durability, these black EPDM washers are designed to reduce noise and enhance retention in custom holster and sheath builds. Sized to fit standard 3/16 inch mounting hardware such as TLMAB posts, Chicago screws, and slotted posts, each washer acts as a buffer between the holster body and the attachment hardware, cushioning contact points and minimizing unwanted rattle. With a durometer around 50, they provide the right balance of flexibility and firmness for a secure hold without compromising movement or comfort. Whether you are crafting a concealed carry holster or a custom field sheath, these washers help create a clean, professional finish while protecting your gear. Sold individually, or choose the 70-piece assortment combo.
Choosing Your Size:
Washer sizes are listed as outside diameter by inside diameter by thickness. The inside diameter fits 3/16 inch posts, and the thickness sets how much standoff, cushion, or gap the washer creates at the mounting point. Choose a thicker washer for more spacing or a thinner one for a lower profile. The 70-piece assortment combo includes a range of sizes for versatility.
