Customer Reviews (4.8 / 5 · 5 reviews)

Evelyn ★★★★★

Needed a solid batch for reassembling some machinery guards and these threaded in clean without any binding. The 2-1/4" length was exactly as marked, and the hex heads grabbed a wrench nicely. Pack of fifty means I've got spares for the next job.

Madison ★★★★★

The yellow zinc coating on these hex cap screws is holding up nicely in my damp shop environment. They seated cleanly with a standard wrench and the 2-1/4" length was exactly what I needed to secure some heavy brackets.

Alexander O. ★★★★★

Threaded perfectly into my equipment brackets with no binding, and the hex heads grabbed my socket wrench cleanly. The zinc yellow coating is evenly applied and should hold up fine in my shop.
