3/8-16 X 10" キャリッジボルト | A307グレードA 亜鉛メッキ鋼 (50個/パック)

Worked perfectly for building a timber frame picnic table — the 10-inch length gave plenty of bite through the wood and the square neck kept every bolt from spinning while I tightened them.

The square neck grabbed tight into the wood right away, no spinning or slipping like I've dealt with before on other bolts. These 10-inch lengths gave me enough reach through the heavy timber frame without any struggle.

Putting these in was a breeze since the square neck kept them from spinning while I tightened the nut. The zinc coating looks clean and should hold up fine in the dry shed where I'm using them.
