براغي رأس سداسي M10-1.5 × 45mm | فولاد فئة 10.9 زنك أصفر | ملولب بالكامل (525/عبوة)

Bought a box of 525 for a production run and honestly didn't expect to get through them all, but the fully threaded design made alignment a breeze and the yellow zinc held up nicely against some pretty grimy shop conditions. Class 10.9 steel feels solid torquing down to spec, no stripped heads even

The yellow zinc coating on these cap screws looks uniform and clean, and the hex heads seated snugly in my socket without any stripping. I’ve used about 200 of them on a steel rack build so far and not a single one has come up short on threads.

These bolts tightened down perfectly with a standard socket—the 10.9 grade gives me real confidence for our milling machine repairs. The zinc coating seems durable, and the full threading made it easy to get a solid grip on the assembly.
