Customer Reviews (4.2 / 5 · 5 reviews)

Edward ★★★★★

I installed these into a 3D printed camera rig and the partially threaded shank gave just the right clamping force without stripping anything. The 18/8 stainless feels solid and the hex drive seated cleanly every time.

Benjamin E. ★★★★★

Needed a long M5 screw for a custom jig and these 40mm ones fit the bill perfectly—the 18/8 stainless feels solid and the threading is clean. Used them to fasten a metal bracket and they tightened up evenly without any cross-threading issues.

Ryan H. ★★★★★

Just swapped out some cheap bolts on my jig fixture for these and the hex socket drive makes a huge difference—no more stripped heads. The 18/8 stainless feels solid and the 40mm length was exactly right for the clearance I needed. Came in a tidy 200 pack, so I’ve got plenty for the next project.
