Customer Reviews (4.6 / 5 · 5 reviews)

Elizabeth W. ★★★★★

The partially threaded shaft made all the difference when fastening through thick brackets, and the yellow zinc finish looks clean. These cap screws held up perfectly under heavy torque without any stripping.

Matthew I. ★★★★★

Needed these for mounting a heavy piece of machinery and the L9 alloy steel feels seriously tough. The yellow zinc finish hasn’t shown any rust after a few weeks in a semi-damp shop, and the partial threads kept the assembly clean where they needed to.

Olivia L. ★★★★★

The threads cut clean and the yellow zinc finish looks uniform across all six bolts, no flaking or rough spots. For a 10-inch partially threaded fastener, the grade L9 strength gives me real confidence in this heavy equipment setup.
