M5-0.8 X 25mm 套件螺絲 | 平頭六角套件驅動 | 全螺紋 | 12.9 級合金鋼 熱處理黑氧化物 (400 個/包)

Fully threaded along the entire shaft, which made dialing in precise depth on my jigs way easier than fumbling with partial threads. The hex socket drive seated the driver snugly with no wobble, and at this quantity I’ve got spares for every fixture on the bench.

The black oxide finish on these M5 screws has held up nicely during assembly, no galling or wear on the hex socket drive. They threaded cleanly into my steel fixture without any binding. Perfect for precision jig work.

Pulled a few out for a jig I’m building — the 25mm length sits flush in the countersunk holes, and the hex drive bit grabbed tight without stripping. The whole pack feels solid, no burrs or wobbles.
