M6 x 20mm 杯點圓柱頭螺絲 | 18/8不鏽鋼 (500入/包)

Used a handful of these for a custom tool holder build and the hex socket drive takes a hex key without stripping. The 18/8 stainless feels solid against rust, which is exactly what I needed for a damp shop environment.

The cup point on these M6 screws digs in nicely for a secure hold on shafts. I used them to lock a gear in place and the hex socket let me torque it down without stripping—great value for a 500-pack.

Needed a solid bag of set screws for a project and these did not disappoint. The hex socket drive made seating them in tight spots surprisingly easy, and the cup point bites down firmly on the shaft. A full 500 pieces for the price feels like a steal.
