مسامير نقل 3/4-10 × 4-1/2 بوصة | خيط كامل | فولاذ عادي A307 درجة A (45 / عبوة)

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.

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.

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.
