5mm Spring-loaded Thumb Socket Screw

7075-T6 aluminum alloy;
Retractable front POM plunger;
Front M6x1.0 thread screw;
10 pieces per box, includes a hex key;
Knurled thumb screws allow initial hand tightening; 5 mm hex keys provide final torque tightening;

The spring-loaded 5 mm hex thumb screws from LBTEK are manufactured from 7075-T6 aluminum, the highest strength grade among common aluminum materials, delivering nearly twice the torsional performance of 6061-T6 aluminum. The front POM plunger effectively prevents post scratching. Knurled thumb screws enable initial hand tightening for positional adjustment. After positioning, 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, with a maximum recommended torque of 3.2 N·m).

Spring-loaded 5 mm hex thumb screws are commonly used for Ø12.7 mm post holders.
