براغي ذات رأس مقبس 1/2-13 × 8 بوصة | محرك مقبس سداسي | ملولبة جزئيًا | فولاذ مقاوم للصدأ 316 (10/عبوة)

Used these on a jig fixture at the shop and the 316 stainless held up great against some light coolant splashes. The partially threaded length gave just enough grip without bottoming out, and the hex socket drive seated cleanly every time.

The hex socket drive gripped perfectly with my Allen wrench, and the 316 stainless steel feels substantial enough for the heavy jig I'm building. No corrosion worries in this marine shop environment.

Finally got these mounted on a saltwater rig, and the hex socket drive made installation a breeze compared to wrenches. The 316 stainless is holding up perfectly against the elements, no signs of rust after a month of heavy use.
