Customer Reviews (4.6 / 5 · 5 reviews)

Olivia E. ★★★★★

The threads on these Grade 8 bolts are clean and consistent, no burs or crooked starts. They drove in smoothly with my impact wrench and the yellow zinc finish looks like it’ll hold up fine in the shop.

Edward ★★★★★

Picked up a pack for a trailer hitch repair and the hex heads seated perfectly with no stripping. The yellow zinc coating looks consistent and should hold up well.

Sebastian ★★★★★

Threads on these grade 8 bolts are clean and precise, seated perfectly in my press frame with the yellow zinc giving a nice uniform finish. For a 3-3/4" length they feel seriously solid, and having a full pack of 20 means I've got spares for the next job.
