براغي رأس أسطواني M5-0.8 × 40 مم | محرك سداسي داخلي | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (200 / عبوة)

Used these to replace some rusty bolts on a boat trailer, and the 316 stainless is exactly what was needed for the saltwater environment. The hex socket drive made installation quick with a standard Allen key. All 200 pieces arrived clean and well-packaged.

The 316 stainless finish is flawless on every single one of these, no burrs or rough edges to speak of. They threaded into my tooling plate cleanly and the hex socket drive grabs perfectly every time, even in tight spots.

Got these for a jig I'm building and the 316 stainless is exactly what I needed—no rust worries in a damp shop. The 40mm length threads all the way through cleanly, and the hex socket fits a standard Allen key snugly. Bag of 200 will last me years.
