## Features

- Each 0.250 SPTHA Slotted Post Holster Mounting Assembly Includes: (1) 0.250 Inch Slotted Post (Black Coated), (1) 0.250 Inch Phillips Truss Head Screw (Black Coated), (1) 0.125 Inch EDPM Washer
- (1) QTY = (12) SPTHRA Assemblies | Commonly called, "Black Chicago Screw Slotted Post Assemblies", these are black oxide coated slotted post truss head holster attachment mounting assemblies that are used to affix common belt clips, belt loops, molle attachments, tek-lock attachments, combat loops, holster wings, speed release attachments, and more.
- Smooth Assembly Surfaces For Maximum Wear Comfort: Each SPTHA holster attachment mounting assembly has been deburred and edge finished to ensure the maximum wear comfort. Just because you sell a screw and a post doesn't make it "wear" well. Care must be taken to smooth the surfaces and edges of each part within the assembly to ensure that the wearer experiences maximum comfort without irritation. Our assembly parts are second to none in holster making, garment manufacturing, canvas, and more.
- EPDM Rubber Holster Mounting Washers (Included): These washers are precisely designed to fit the post assembly. The through-hole on each washer perfectly fits the shaft of each mounting post and does not require the inside protrusions found on the inferior washers being offered that allow them to claim “tightness”. Our washers are designed exclusively for perfect fit on each CKK mounting post.
