M3-0.5 x 10mm 內六角圓柱頭螺絲 | 平頭內六角驅動 | 全牙 | 10.9級合金鋼鍍鋅 (800入/包)

The hex socket drive makes tightening these into my 3D printer's aluminum frame effortless, and the zinc plating gives them a nice uniform finish. For a precision assembly job, having 800 pieces means I won't run out mid-project.

I’ve been using these for small jig assemblies and the hex socket drive makes installation much easier than standard slotted heads. The full threading gives good grip in thin materials, and the whole box arrived well organized.

The hex socket drive seated perfectly on my Allen key with zero stripping, and the 10.9 alloy steel feels tough enough for repeated use in my jigs. All 800 pieces arrived uniformly threaded and the zinc plating gives them a clean, even finish that should hold up fine in my shop.
