M6 x 16mm 平頭內六角止付螺絲 | 合金鋼 (500顆/包)

These hex screws fit perfectly in my adjustable workbench stops, and the flat point makes them sit flush without catching on anything. The 500-count bag is way more than I’ll use at once, but the price was right for stocking up.

I needed a bunch of these for a jig I’m building, and the alloy steel feels really tough under the hex wrench. The flat point seats nicely without marring the shaft.

The hex socket drive on these M6 set screws gives me a firm grip even in awkward spots, and the flat point seats perfectly against the shaft. For 500 pieces, the alloy steel feels sturdy enough for heavy use.
