Customer Reviews (4.4 / 5 · 5 reviews)

Riley V. ★★★★★

The zinc plating on these bolts is holding up great against rust in my damp workshop. Threads are clean and consistent across all 100 pieces, so they started into my steel bracket without binding. Exactly what I needed for joining metal frames.

Julian U. ★★★★★

I needed a full-length thread for a bracket repair, and these 3/8-16 bolts delivered perfectly with a clean zinc finish. The 100-pack means I have spares for future projects.

Stella ★★★★★

These hex bolts threaded smoothly through my steel bracket without any binding. The 3/4" length was perfect for my project, and having a full pack of 100 means I won't run out mid-job.
