Customer Reviews (4.6 / 5 · 5 reviews)

Abigail N. ★★★★★

Needed a solid bolt for a heavy-duty fence repair and these held up perfectly under torque. The zinc plating gives them a clean, consistent finish that should resist rust well.

Adam ★★★★★

Used a full box on a custom welding jig and every bolt threaded smoothly without binding. The zinc coating held up fine against occasional sparks, and having 1,000 fully threaded bolts made assembly much faster than hunting for partial thread ones.

Alexander I. ★★★★★

Bought these for a big metal rack build and the fully threaded shank made adjusting joints way easier than I expected. The zinc coating looks clean and they came in a sturdy box that survived the delivery. Exactly the 3/8-16 size I needed, no fuss.
