Often called black Chicago screw assemblies, the HOLSTEX® SPTHA (Slotted Post Truss Head Attachment Mounting Assembly) is a black oxide coated slotted post assembly made for mounting belt clips and other common holster attachments, including Tek-Loks, Combat Loops, FOMI clips, Flush Mount clips, Molle locks and many more. Its EPDM washer gives just the right amount of cushion and grip for fastening clip attachment fascias to KYDEX®, HOLSTEX®, Boltaron® or leather. The 8-32 truss head screw is exclusive to HOLSTEX® and has the thinnest edge you will find on this type of design, so the leading edge keeps surface irritation to a minimum where it rubs against clothing or skin. Professional KYDEX and leather holster makers and government holster contractors around the world use it.
What comes in each SPTHA assembly
- One slotted post, black coated
- One Phillips truss head screw, black coated
- One EPDM washer
How to pick a size
Size refers to the slotted post length, which should match the thickness of material you are mounting through. The 0.125 inch model is just the right length for mounting attachments on .060 inch up to .093 inch material, and the 0.250 inch, 0.375 inch and 0.500 inch sizes step up for thicker stacks. The 0.125 inch comes in Standard and Large versions. Pick the size that matches the combined thickness at your mounting point.
