Michael Z. ★★★★★

Finally got these for a project needing that precise 3/8-24 thread, and the zinc plating has held up well against a damp workshop environment. The consistent hex head size made tightening torques much easier to gauge with my wrench. Glad I bought the 90-pack, as I used half just for one assembly.

Thomas ★★★★★

The partially threaded shank made aligning these bolts in tight spots much easier, and the zinc plating looks clean and uniform across all 90 pieces. Held up perfectly for securing steel brackets without any binding issues.

John ★★★★★

The partially threaded shank on these bolts gave me just the right grip length for a tight frame connection I was working on. Zinc plating looks clean and should hold up fine in my garage.
