Customer Reviews (4.8 / 5 · 5 reviews)

Victoria ★★★★★

The yellow zinc finish on these bolts is just right for resisting a bit of moisture without being too shiny. I used them to fasten a steel bracket to a trailer frame, and the unthreaded grip length made alignment much easier.

Violet ★★★★★

The partially threaded shank gave me that exact grip length I needed for a tight bolted connection, and all 50 came out of the box with clean threads and uniform plating. The zinc yellow coating has held up fine so far, no flaking after a few days of handling.

Aurora ★★★★★

The partially threaded shank made alignment a breeze on my drill press table; the grip length held firm without any slipping during assembly. Zinc plating looks good and should resist rust in my damp garage.
