Customer Reviews (4.8 / 5 · 5 reviews)

Aurora I. ★★★★★

The hex head on these cap screws grabbed my socket wrench perfectly, no slipping at all during assembly. The yellow zinc finish looks professional and seems durable for industrial use. Exactly what I needed for a sturdy equipment mount.

Violet ★★★★★

Used these to bolt down a heavy press at work, and the yellow zinc finish actually held up to some oil and grime without rusting. Was a little worried about the 5-1/2" length being a pain to torque, but the hex heads took a socket cleanly and everything seated flush. Glad I went with the USA made on

Sophia ★★★★★

The hex heads on these screws gripped my socket perfectly without any slipping, even under heavy torque. The yellow zinc coating looks like it'll hold up well against rust in my shop environment.
