M6-1 x 60mm 內六角圓頭螺絲 | 平頭內六角驅動 | 部分螺紋 | 316不鏽鋼 (100 / 包)

The hex socket drive makes these so much easier to tighten in tight spots than regular slotted screws, and the 316 stainless steel feels like it will hold up far longer than the cheap ones I'd been using. For the price of a 100-pack, it's hard to beat the precision threading on these for jig assembl

I’ve been through a few boxes of cheap screws that stripped on the first torque, but these 316 stainless ones held up beautifully in my jig build. The hex socket drive seated perfectly with my Allen key, and the partial thread gave just the right grip without bottoming out.

The partially threaded design made alignment in my jig setup way easier than fiddling with fully threaded bolts, and the 316 stainless has that reassuring weight. I've already used about half the pack on outdoor machinery and not a single one has shown any rust after a week of rain.
