Lily Q. ★★★★★

Had to replace some stripped bolts on a jig setup, and these 10.9 alloy steel screws threaded in perfectly without any wobble. The hex socket drive grabbed the wrench firmly, and the 55mm length was exactly what I needed for a tight assembly. A solid upgrade over the random hardware store fasteners

Timothy ★★★★★

The hex socket drive seated perfectly on my driver, no stripping even when torquing them into steel. The thermal black oxide finish looks clean and uniform across all 200 pieces. I’ve used about half on a jig build and every one threaded smoothly to the full 55mm length.

Timothy T. ★★★★★

The black oxide finish on these screws looks sharp and professional on my latest jig build, and the hex socket drive made installation a breeze with no stripping.
