Spring-loaded 5mm hex hand-tightened screw
  • Main body material: 7075-T6 high-strength aluminum alloy or 303 stainless steel
  • Retractable front POM plunger
  • Front M6x1.0 thread
  • 10 pieces per box, with hex key
  • Hand-knurled knob for initial tightening, 5 mm hex for final tightening

LBTEK spring-loaded 5 mm hex thumbscrew is made of 7075-T6 aluminum, the highest strength among common aluminum materials, or 303 stainless steel. The 7075-T6 material offers nearly twice the torsional performance of 6061-T6 aluminum, while the 303 stainless steel further increases torsional performance by nearly double compared to 7075-T6 aluminum. The front POM plunger effectively prevents scratching the post, and the knurled thumb screw provides initial tightening for easy positioning adjustment. Once the position is set, a 5 mm hex wrench can be used to reinforce clamping (note: excessive torque may cause the locking screw to break; it is recommended to use an L-shaped hex wrench and tighten gently by holding the short end. The recommended maximum torque for 7075-T6 material is 3.2 N·m, and for 303 stainless steel material is 8 N·m).

Spring-loaded 5 mm hex thumb screw is commonly used for Ø12.7 mm Post Holder.
