M3 X 10mm 內六角螺絲 | 平頭六角驅動 | 合金鋼 (100 入/包)

I needed a small batch of M3 screws for a jig I was building, and these flat head cap screws fit perfectly. The alloy steel feels sturdy, and the hex drive holds the wrench securely without stripping.

The hex socket drive grabs my Allen key perfectly every time, no stripping or wobble even after tightening several into a jig. Alloy steel feels solid and the flat heads sit flush, which is exactly what I needed for a precision assembly. Overall, a reliable box of 100 for the price.

I’ve been swapping out standard machine screws for these on my jigs and fixtures, and the hex socket drive makes them so much easier to torque down in tight spots. The alloy steel feels plenty sturdy for the precision assemblies I’m working on, and the flat head sits flush without any wobble.
