M16-2 X 55mm 內六角螺絲 | 六角驅動 | 全牙 | 18/8 不鏽鋼 (25 / 包)

Used a pair of these to secure a heavy-duty jig on my milling table, and the fully threaded design gave me plenty of grip depth. The 18/8 stainless feels solid and corrosion-resistant, which is exactly what I needed in my shop.

Was a bit worried about the hex drive stripping, but these 18/8 stainless screws seated cleanly into my aluminum tooling and held torque without any galling.

Fit perfectly into my jig fixture without any binding, the hex socket drive seated the wrench nice and deep. All 25 came out of the package with zero burrs or scratches on the 18/8 stainless finish. These are going straight into my permanent tooling setup.
