مسامير عربة مقاس 3/4-10 × 4 بوصة | خيط كامل | فولاذ عادي درجة A307 Grade A (50/عبوة)

The square neck on these pulled right into the wood and held perfectly while I tightened the nut—no slipping at all. This 50-pack is a solid deal for the size.

Had to replace the rusted bolts on my boat trailer bunks and these carriage bolts fit perfectly. The square neck grabbed into the wood immediately, no spinning while tightening.

Used a dozen of these on a cedar pergola beam and the square neck dug in exactly as it should, so no spinning while I torqued them down. The 3/4-10 threads are fully cut and the plain steel finish is fine for outdoor work if I paint them. Bag of 50 means I've got plenty left for the next project.
