Eli ★★★★★

The square neck under the head grabbed the wood instantly when I tightened them, so no spinning or cursing. Full threads on all 45 of them made the whole job go faster than I expected for this size.

Alexander ★★★★★

Perfect fit for my heavy-duty trailer build—the fully threaded length gave me plenty of grip through thick lumber. These bolts are solid and the square neck locked in securely without spinning.

Carter J. ★★★★★

The square neck grabbed the wood on the first pull, so I didn't fight a single spinning bolt while framing the deck. The A307 steel machined cleanly with a tap, too. These are plenty beefy for heavy structural work at a fair price per pack.
