M3 x 3mm 杯端內六角止付螺絲 | 316不鏽鋼 (500個/包)

The hex socket drive made torquing these into my jig a breeze even in the tightest corners, and the 316 stainless gives me peace of mind against rust in the shop. I've already burned through half the pack on a single project, so the 500 count is a solid deal.

The cup point on these screws grips firmly even in tight spots, and the hex drive handles a surprising amount of torque for such tiny fasteners. I used them for marine hardware and the 316 stainless holds up perfectly against corrosion.

I needed stainless fasteners for a saltwater environment, and these 316 cup points are exactly what I was looking for. The hex socket drive held up perfectly during installation in a tight corner on my boat's railing.
