Customer Reviews (4.8 / 5 · 5 reviews)

Joshua N. ★★★★★

Perfectly matched the 170mm length I needed for a jig fixture. The hex heads grabbed my socket cleanly without slipping as I torqued them into position.

Amelia Q. ★★★★★

Oddly satisfying to tighten these down with a socket—the hex head grabs perfectly without any slipping. The zinc plating looks clean and feels durable for outdoor machinery use. Exactly the length I needed for a heavy-duty frame bracket.

Penelope ★★★★★

These hex bolts fit perfectly on my press frame assembly, and the zinc plating gives a clean, rust-resistant finish. The 170mm length was just right for the thick bracket I needed to secure, and the hex head made tightening with a socket wrench fast and easy.
