Customer Reviews (4.6 / 5 · 5 reviews)

Robert O. ★★★★★

Finally a bolt that threads cleanly into standard nuts without any binding. The 4-1/2" length with partial threading gave me just enough grip for a heavy equipment mount, and the zinc finish looks like it’ll hold up well in the shop.

Robert D. ★★★★★

The zinc coating on these 3/4-10 bolts is uniform and thick, which should hold up well in my shop environment. The partial threading makes them perfect for bolting down heavy equipment where you need full thread engagement in the nut.

Andrew Y. ★★★★★

Finally got to use these on a heavy equipment mounting job and the partial threading made alignment so much easier. The zinc coating looks smooth and uniform across all 55 pieces.
