M16-2 X 140mm 소켓 캡 나사 | 육각 소켓 드라이브 | 부분 나사산 | 316 스테인리스 스틸 (25개/팩)

I’ve used a lot of hex socket screws in jigs, and the 316 stainless here gives me real peace of mind against rust in a damp workshop. The partially threaded length on the 140mm shaft seated perfectly through my fixture without any binding. These are the ones I’ll grab first next time.

Finally, a socket cap screw that doesn't strip after moderate torque—the 316 stainless steel feels noticeably tougher than the 304 I've used before. I installed a batch in a jig fixture and the partial threading lined up perfectly with the clamping depth I needed.

The hex socket drive made torquing these down a breeze, and the 316 stainless steel feels rock solid against corrosion. Threads were clean and seated perfectly into my jig setup without any binding.
