Installation & Usage Guidelines
-
Hole Preparation: Ensure the hole diameter in your material matches the outer diameter of the female post (not the screw thread) for a snug fit.
-
Grip Length Selection: Choose a post length that is slightly shorter (0.5 mm to 1 mm) than the total material thickness to ensure the heads can tighten down fully.
-
Thread Locking: For permanent applications (like holsters), a drop of removable thread locker (e.g., Loctite 242) is recommended to prevent vibration-induced loosening.
-
Manual Tightening: Do not over-torque brass versions, as brass is softer than steel and the drive slot may deform.
