Premium 18-8 Stainless Steel Carriage Bolt 5/16"-18 x 5/8" (Pack of 1,000) - Heavy-Duty Fasteners for Construction, Marine & Outdoor Projects

Features

A carriage bolt has a domed or countersunk head and the shank is topped by a short square section under the head of the bolt.

The square section grips into the part being fixed, preventing the bolt from turning when the nut is tightened.

Carriage bolts are often used to fasten wood panels or board to masonry or to one another.

The square shank of the bolt allows it to lock into place when inserted into a round hole in wood or a square hole in a metal strap, the unthreaded square shank pulls into the wood creating a tight connection.

18-8 Stainless steel is corrosion and rust resistant. 18-8 Stainless steel is considered the fastener industry standard.
