Customer Reviews (4.8 / 5 · 5 reviews)

Matthew T. ★★★★★

The zinc coating on these screws looks great and should hold up well in my shop environment. They drove in smoothly with a socket and the partial threading made alignment easy.

Matthew ★★★★★

Needed a dozen of these for a heavy-duty press rebuild and the 5-inch length paired with the partial threading made alignment a breeze. The yellow zinc finish looks tough and the L9 grade holds torque perfectly under load.

Timothy B. ★★★★★

The partial threading really helps when I need a smooth shank for alignment, and the yellow zinc finish is holding up well after a week of outdoor use. These Grade L9 heads took my impact wrench without stripping, which is exactly what I needed for heavy equipment assembly.
