براغي رأس كبس M8-1.25 × 40 مم | رأس زر محرك سداسي | خيط كامل | ستانلس ستيل 316 (100 / عبوة)

Installed these on a marine railing project and the 316 stainless is holding up perfectly against the salt spray. The button head profile sits flush without snagging anything.

The hex socket drive grips perfectly with a standard Allen key, no stripping even when I torqued them down hard on a jig fixture. Fully threaded 40mm length gave me plenty of bite in the aluminum frame, and the 316 finish hasn't shown a speck of rust after a week of coolant exposure.

Finally, 316 stainless socket caps that don't show surface rust after a few weeks on my marine gear. The hex drive seated perfectly in my driver without any stripping, and the 40mm length was exactly what I needed for those thicker brackets.
