براغي رأس سداسي M12-1.5 × 80 مم | فئة 10.9 من الصلب العادي | ملولبة بالكامل (200/عبوة)

Installed these on a small press jig I've been building, and the 80mm length was spot-on for clamping heavy plates. The threads ran smooth with no binding, and the hex head sat flush with my socket driver. For 200 pieces at this grade, it's a solid buy.

Installed these on a conveyor belt guard where the old bolts had stripped out. The 10.9 grade steel torqued down solid without any thread deformation, and the fully threaded shaft gave me plenty of engagement in the nut.

These are exactly the length I needed for a heavy equipment frame I'm welding up, and the hex heads give my socket a solid grip without slipping. The 80mm length with full threading meant I didn't have to fight with partial engagement on thick flanges. Definitely buying another pack when I run low.
