Fastener SuperStore Offers Carriage Bolts in a Wide Variety of Styles, Sizes, Materials & Finishes!

Standard Carriage Bolts feature a round head, a square neck under the head and a standard unified thread pitch. The square neck is designed to keep the bolt from turning as a nut is tightened onto it.

Fastener SuperStore offers a wide selection in full and partial threads (partial threading generally found on longer bolts).

Materials offered include steel, grade 5, grade 8, 18-8 stainless and 316 stainless. Finishes include zinc, black oxide, hot dipped galvanized, as well as plain steel options.

Ribbed Neck Carriage Bolts offer the same head shape as standard carriage bolts but replace the square shape under the head with vertical ribs that are slightly wider than the diameter of the bolt. The ribs help prevent the bolt from turning as a nut is tightened or removed.

Ribbed neck carriage bolts are offered in steel and grade 5 with a zinc finish, and in 18-8 stainless steel.

.

Short Neck Carriage Bolts have the same features as standard carriage bolts, except that the neck under the head is shorter. They are commonly used in sheet metal where a standard sized neck would be too large and would potentially create an obstruction.

All of our short neck carriage bolts are fully threaded and are made of steel with a zinc finish.

We also carry a selection of timber bolts & track bolts.
