M3 x 5mm 平頭止付螺絲 | 合金鋼 (1000入/包)

The flat point on these M3s is machined cleaner than any pack I've bought before, and the hex socket grabs the driver without any wobble. I've already used about 200 of them on a jig build and not one stripped or rounded out.

Finally, a set screw that actually stays put without stripping — the hex socket lets me get proper torque even in the tightest spot. I've been through a few brands and these alloy steel ones feel much tougher.

Perfect fit for those tight little jobs where standard hex keys just won't reach; the flat point tip makes them easy to start without stripping, and the 1000-count pack should last me years.
