M3-0.5 x 12mm 內六角螺絲 | 內六角驅動 | 全螺紋 | 316不鏽鋼 (800顆/包)

These M3 screws are perfect for my jig fixtures—the full threading gives a much better grip than partial threads I've used before. The hex socket drive is clean and the 316 stainless finish feels solid.

The hex socket drive on these M3 screws grips the driver perfectly with no slipping, and the 316 stainless steel feels noticeably more robust than standard hardware. I used a full bag on a custom jig and every single thread was clean and consistent.

Was pleasantly surprised by the quality of the hex socket drive—it grabbed my Allen key perfectly without any wobble. I used a dozen on a test fixture and they all threaded smoothly, even in the tight spots. Solid little screws for the price.
