Customer Reviews (4.8 / 5 · 5 reviews)

Richard B. ★★★★★

The hex socket sat perfectly flush in my driver—no wobble, no stripped corners even after torquing a few down in a tight jig. The zinc plating’s holding up nicely so far, and the 55mm length gave just enough grip for my 12mm-thick bracket stack.

Claire ★★★★★

The hex socket drive seated my Allen key perfectly on every single screw, and the zinc plating looks clean and uniform across all 200 pieces. I’ve been using them for a jig assembly and they thread in smoothly without any binding.

Penelope R. ★★★★★

I needed a batch of M6x55mm socket caps for a jig I'm building, and these fit perfectly with clean threads and consistent depth across all 200 pieces. The zinc plating is even and hasn't chipped during installation.
