M12-1.25 X 120mm براغي غطاء بمقبس | محرك مقبس سداسي | خيط جزئي | سبيكة فولاذ درجة 12.9 معالجة حرارياً بأكسيد أسود (25 / عبوة)

Needed some heavy-duty screws for a press fixture, and these 120mm long ones handled the load without any flex. The black oxide finish feels solid and the hex socket engaged perfectly with no stripping.

Slightly longer than my last batch of M12s, but the 120mm length gave me just enough bite for a thick fixture plate. The black oxide finish looks clean and the hex drive seated firmly without any wobble.

Used a few of these to secure a jig for a milling project and they held up perfectly under heavy load. The Class 12.9 alloy steel feels noticeably tougher than standard hardware, and the partial threading made alignment much easier.
