Customer Reviews (4.6 / 5 · 5 reviews)

Emily W. ★★★★★

The zinc plating on these is even and smooth, and the threads caught perfectly on the first try. I used them to secure a heavy-duty bench to concrete anchors, and they haven't budged.

Aurora ★★★★★

Used a few of these to bolt down a piece of equipment at the shop, and the partially threaded length grabbed perfectly without any wobble. The zinc coating is holding up fine so far, no rust after a couple of rainy days outside. Exactly what I needed for a solid, no-nonsense connection.

Olivia ★★★★★

The partial threading made these grab perfectly when I was assembling a heavy-duty press frame. They threaded in smoothly without any binding, and the zinc coating looks clean and consistent.
