M8-1.25 X 35mm 內六角螺絲 | 平頭內六角驅動 | 全螺紋 | 10.9級合金鋼熱處理黑氧化 (200顆/包)

Used a dozen of these to mount a heavy steel bracket on a workbench, and the black oxide finish held up well against the wrench without chipping. The hex socket drive made them easy to tighten in tight spots, and at 35mm length they were perfect for sandwiching two pieces of 10mm plate.

Installed these in a jig I’m building and all 200 pieces threaded cleanly with no burrs, the black oxide finish looks professional and held up against the wrench.

The hex socket drive seated perfectly with my Allen wrench, and the black oxide finish looks clean on my jig. Threads ran smooth through the tapped holes once I hit them with a little oil. Solid 10.9 alloy steel feel, no stripped edges even torquing them down.
