Customer Reviews (4.2 / 5 · 5 reviews)

Nicholas ★★★★★

The threads cut cleanly and seated fully without any binding, which made the assembly go quicker than I expected. Yellow zinc finish looks consistent across all 25 pieces, and the hex head grabs a socket snugly with zero rounding.

Evelyn C. ★★★★★

Used these to fasten a bracket on my press and the hex head fit my socket perfectly—no slipping at all. The 10.9 steel feels solid and the yellow zinc coating adds a nice touch of corrosion resistance. Just what I needed for a reliable hold.

Kevin ★★★★★

Grabbed a pack for a few heavy-duty assembly projects around the shop. The fully threaded design grips securely into the material, and the 50mm length was spot-on for my needs. The yellow zinc finish seems tough so far.
