براغي رأس سداسي ثقيلة 5/8-11 × 1-3/4 بوصة | فولاذ سبائكي ASTM A193 B7 عادي | ملولبة بالكامل (180/عبوة)

Threads cut clean and the B7 alloy is noticeably tougher than the grade 5 stuff I’ve used before, these seated without any galling. The fully threaded length made alignment a breeze on the equipment frame I was bolting together.

Needed some heavy-duty fasteners for mounting a press brake, and swapping to these B7 alloy screws gives me much better peace of mind than the standard hardware I was using. The full threading on these 5/8-11 x 1-3/4" cap screws bites deep and holds firm, even in my older equipment.

The threads are clean and consistent from one screw to another, so my flange assembly came together without any binding. For the price per piece on these B7s, they’re a solid deal for any heavy-duty job.
