Ø12.7 mm Post Holder PH-40A-P5

The standard Ø12.7mm post holder from LBTEK features a standard ultra-wide square relief groove, providing dual-line contact to prevent optical posts from sliding or rotation. The precision-engineered spring-loaded knurled thumb socket set screw (M6) should be tightened to <3.2N·m torque, and a 5 mm hex key reinforces the clamping force. (Note: Excessive torque may cause the locking screw to break. It is recommended to use an L-shaped hex key and gently tighten by holding the short end). The PH-xxA series post holder features an M6 tapped through-hole at its base: This allows flexible pairing with either a magnetic base (PR-1S) or a non-magnetic base (PR-1A). It can also be directly used with the PB-x series mount or secured to a breadboard by threading an M6 screw.
