براغي رأس سداسية M12-1.75 × 240 مم | فئة 10.9 فولاذ عادي | ملولبة جزئيًا (8 / عبوة)

The partial threads grabbed perfectly when I torqued them down on the equipment frame—no slipping at the shoulder. Class 10.9 steel feels plenty stout for the job, and the hex heads took a socket without rounding. Solid pack for the price, glad I grabbed these.

Needed longer bolts for a heavy-duty press build and these 240mm ones fit perfectly. The partially threaded design gave just the right grip depth without bottoming out. They seated squarely with a socket wrench, no issues at all.

These bolts handled the frame jig assembly without any wobble, and the hex head gave my socket a solid grip even with a cheater bar. The 240mm length with partial threading is spot on for joining thick plates with a nut to spare.
