M8-1.25 x 20mm內六角螺絲 | 六角驅動 | 全螺紋 | 12.9級合金鋼熱處理黑氧化物 (400個/包)

The black oxide finish on these M8-1.25 x 20mm screws looks sharp and holds up well against scuffs in my workshop. Threads ran clean into my tooling fixtures without any binding, and the hex socket drive seated perfectly every time. For a full box of 400, this is solid value.

Used these on a jig I'm building and the hex socket drive seated perfectly with no stripping. The 12.9 alloy steel feels seriously strong for the price, and having 400 in one box means I won't be running out anytime soon.

The black oxide finish on these M8 socket cap screws is really uniform and professional-looking, and the hex drive fit my Allen key perfectly without any wobble. They’re holding up great in the precision assembly I’m working on.
