#2-56 X 3/8" 圓柱頭螺絲 | 按鈕頭六角凹槽驅動 | 合金鋼 (300個/包)

The hex socket drive grips the Allen key perfectly, no stripping even when I torqued them down in a tight jig. For 300 alloy steel screws at this price, they’re a solid buy for precision work.

I’ve used a handful of these in a small jig and the hex socket drive grips the wrench without any stripping, even at such a tiny size. The alloy steel feels solid and the button head sits low enough for tight spots. Exactly what I needed for precision work.

Finally found #2-56 socket cap screws that don't strip out on the first use—these button heads fit perfectly in my jig’s tight spaces. The hex socket drive actually grips well with a standard wrench.
