Customer Reviews (5.0 / 5 · 5 reviews)

Natalie ★★★★★

I was pleasantly surprised by how clean the rounded head sits flush against the wood surface, no snagging like with hex bolts. The full threading gives a solid grip when fastening, and the whole box of 3750 came neatly packed without any rust spots.

Evelyn B. ★★★★★

The square neck on these bolts grabbed into the wood perfectly, no spinning at all when I tightened them. For the price per pack, having 3,750 pieces in plain steel is a great deal if you do a lot of framing or deck work. Just make sure you have a good driver bit for the dome head.

Penelope ★★★★★

I was pleasantly surprised by how uniformly threaded these bolts are—every single one in the box spun on smoothly without any burrs. The square neck seated perfectly in the wood, no spinning at all during installation.
