QuickClip Pro These are what got us started, hard to find open back-slotted posts. We had a military contractor looking for a heavy duty 1/8? Binding Post Hardware for some bags & holster attachments. We searched everywhere to find these but couldn?t and resorted to having the tooling made for us in the USA. These are not your average Chicago binding posts and screws, these are made to exceed Mil-Spec standards, even our Black Oxide Finish is an Ultra Deep Black that will outlast any other brand. They are mostly used for mounting knife sheath and gun holster attachments, fixing & fastening leather straps, sandal buttons, boots, belts knives, use in place of fastener rivets. Because they are slotted, they can be easily tightened or removed. These use an industry standard #8-32 thread. Screwpost Packs in quantities of 10 or 25 piece match sets. SPECIFICATIONS: ?
