براغي رأس مقبس M5-0.8 × 30 مم | محرك مقبس سداسي | ملولبة جزئيًا | فولاذ مقاوم للصدأ 18/8 (300/عبوة)

Used these to rebuild a jig for my CNC and the hex socket drive held up perfectly under repeated tightening. The partially threaded design gave me just the right grip depth without bottoming out.

Finally, a socket screw that doesn't strip the hex drive on the first use; the 18/8 stainless steel feels solid for my jig builds. I also appreciate the partially threaded length, which holds tight without bottoming out.

The partially threaded design made installation in these jigs much easier than with fully threaded bolts. The hex socket drive grips well, though a couple screws had slightly burred edges right out of the bag.
