✔ In Stock — Ships Today
The Ø38 mm post collar from LBTEK features four mounting points: a M6 countersunk mounting hole at the top, a M4 tapped hole on each of the two 45°-angle sides, and a M6 tapped hole on the lateral side. This collar slides along the post to the desired position and is secured by tightening the rubber-tipped screw with a 5 mm hex key. Typically, the M4 tapped holes connect to optomechanical components with M4 countersunk or tapped holes (e.g., lens mounts or apertures). It also connects to components with M6 screw threads (e.g., breadboards) via M6 countersunk or tapped holes.
