براغي رأس مقبس M14-2 × 40 مم | محرك مقبس سداسي | كاملة الخيوط | فولاذ مقاوم للصدأ 316 (50 / عبوة)

I needed strong bolts for a marine railing repair, and these M14-2 screws held up perfectly with no signs of rust after a week in salt spray. The 316 stainless steel feels solid and the threading was clean all the way.

The hex socket drive fits my Allen key perfectly with zero wobble, and the 316 stainless finish looks clean even after sitting in my toolbox for a week. These M14s are going into a jig I’m building, and the threading feels precise all the way down. Solid purchase for the price.

Installed a full set of these on a saltwater boat trailer, and the 316 stainless is holding up perfectly against corrosion. The hex socket drive made tightening them in tight spots much easier than a standard hex head.
