براغي رأس أسطوانية 7/8-9 × 3 بوصة | فتحة سداسية | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (10 / عبوة)

The hex socket drove in cleanly without any stripping, and the 316 stainless finish feels substantial for marine-grade work. Threads were true to size all the way down, which saved me a lot of re-tapping hassle.

Used a few of these to replace some old bolts on a machine fixture, and the 316 stainless steel is noticeably more corrosion resistant than the standard hardware I had before. The hex socket drive made installation easy with an Allen key.

The hex socket drive seats perfectly on my Allan key, and the 316 stainless is exactly what I needed for a marine jig I'm building. Threads are clean and ran through a tapped hole without any binding. Solid pack of ten for the price.
