براغي رأس أسطوانية M20 × 100 مم | محرك سداسي | فولاذ مقاوم للصدأ 18/8 (4/عبوة)

The hex socket drive gripped the Allen key perfectly, no slipping even when I torqued it down on a heavy jig. For an M20 this size, the 18/8 stainless finish looks clean and feels solid. These are my new go-to for precision assemblies.

I needed a long, strong screw for a heavy jig I’m building, and these M20 x 100mm bolts fit perfectly—the hex socket made driving them into tight spots much easier than a slotted head. The 18/8 stainless steel feels solid and should resist rust in my shop.

Finally, a hex socket screw that doesn't strip under load—the 18/8 stainless held up perfectly when I torqued it into my press fixture. The 100mm length gave me just enough thread engagement without any wobble.
