براغي ذات رأس أسطواني 5/8-11 × 4 بوصة | محرك سداسي | ملولبة جزئيًا | فولاذ مقاوم للصدأ 316 (10/عبوة)

I was a little worried about the hex socket stripping on a bolt this size, but the drive engagement feels solid and precise. They threaded smoothly into my jig without any binding, and the 316 stainless gives me confidence they won't rust in my damp workshop.

These 316 stainless screws held up perfectly for my jig build, no corrosion issues after a week in a damp shop. The hex socket engaged securely without stripping, and the partial threads made alignment a breeze.

Threads cut clean and the hex drive seated perfectly on the first try—no galling at all on the 316 stainless. These are going to hold up way better than the zinc-plated set I used before.
