براغي ذات رأس سداسي ثقيل 7/8-9 X 7 بوصة | ASTM A193 B7 سبيكة فولاذ عادي | ملولبة جزئياً (30 / عبوة)

The threads cut cleanly and started by hand even in tight holes. These hex cap screws feel solidly made and should hold up well under load.

Used them to bolt down a heavy baseplate on the shop floor and they seated perfectly with a wrench, no stripping even at full torque. The 7/8-9 thread took the partial thread engagement fine, and the pack of 30 gave me plenty of spares for the next job.

The threads cut clean and the partially threaded length gave me just the grip I needed on a heavy equipment frame. The B7 alloy steel feels dense and solid, no flex when torqued down. These are the ones I'll grab again for the next assembly.
