M20-2.5×150mm 內六角平頭螺絲 | 平頭內六角驅動 | 全螺紋 | 18/8 不鏽鋼 (10入/包)

The hex socket drive on these M20 screws bit perfectly with my Allen wrench, no wobble or stripped corners. Threads on all ten pieces were clean and consistent, which made racking them into my jig a breeze. Solid stainless steel feel, exactly what I needed for a permanent fixture.

Installed a few of these in a tooling fixture and the hex socket drive made tightening much easier than a standard hex head. The 18/8 stainless steel seems solid and the threads are clean all the way down. Exactly what I needed for a sturdy jig setup.

Needed a fully threaded M20 bolt for a jig I'm building, and the 150mm length was exactly right. The stainless steel feels solid and should hold up well in the shop.
