Customer Reviews (4.8 / 5 · 5 reviews)

Miles I. ★★★★★

Was a bit skeptical about the thread fit on an 11/8-12, but these threaded into my jig block perfectly with no binding. The black oxide finish gives them a nice grip feel, too.

Jacob H. ★★★★★

Had to replace a critical bolt on my milling jig and these threaded in smoothly without any binding. The black oxide finish held up well under the wrench, no chipping.

Timothy P. ★★★★★

The hex socket drive bit into my torque wrench seamlessly, and the black oxide finish hasn't chipped during repeated assembly and disassembly. These are solid, precision fasteners that hold firm under pressure.
