Ø12.7 mm Post Holder PH-50B-P5

The base-type post holders from LBTEK adopt a compact design, featuring a precision-engineered spring-loaded knurled thumb socket set screw (M6). The maximum torque when tightening the thumb screw should be <3.2N·m, and a 5 mm hex key reinforces the clamping force (Note: Excessive torque may cause the locking screw to fracture. It is recommended to use an L-shaped hex key gripped at the short end for gentle tightening.). The integrated magnetic base has a thickness of 4.7mm, providing strong magnetic holding force. When used with the PHC-45 clamping fork, it can be flexibly secured to an optical breadboard. The bottom through-hole design allows for maximum post height adjustment.
