Customer Reviews (4.8 / 5 · 5 reviews)

Abigail ★★★★★

The square neck on these grabbed the wood instantly with my mallet, no spinning at all even on the first drive. Fully threaded means I could cinch down a thick 2x6 and still have plenty of bite left on the nut.

Michael D. ★★★★★

Used these to rebuild a wooden planter box and the square neck grabbed perfectly into the wood, no spinning or slipping even under heavy wrench torque.

Victoria ★★★★★

All two hundred arrived clean and dry, with the threads cut clean along the full length. They were exactly the right depth for a sturdy bench frame, and the smooth rounded head sits flush without snagging my work aprons.
