M3-0.5 x 10mm 內六角螺絲 | 平頭六角驅動 | 全螺紋 | 18/8 不鏽鋼 (1800個/包)

The hex socket drive grips the Allen key perfectly, no stripping even when I torqued them down tight on my jig. For an 1800-piece box of 18/8 stainless, the thread consistency is impressively uniform across the batch. Definitely my go-to for precision assembly now.

Had to replace some stripped screws on a 3D printer bed and these flat heads sit perfectly flush. The hex socket drive made installation quick, and the 18/8 stainless steel gives me confidence they won't rust.

Packed 1,800 of these M3 screws in one bag, and every single one I’ve checked has clean threads and a snug hex fit. The flat head sits flush in my assembly jigs, which is exactly what I needed.
