Customer Reviews (5.0 / 5 · 5 reviews)

Scarlett ★★★★★

The partially threaded design on these 5-inch screws makes them perfect for the heavy machinery jig I was building. The yellow zinc coating looks durable and the hex heads grabbed my socket wrench cleanly without any slipping.

Sofia ★★★★★

Finally, some bolts that don’t strip when torqued down tight. The yellow zinc coating looks solid and should hold up well in my shop equipment.

Miles X. ★★★★★

Just used these to rebuild a tractor’s PTO shaft assembly and the partial threading made seating the lock washers so much easier. The yellow zinc coating seems more durable than the standard black oxide bolts I’ve used before.
