B18.5 Carriage Gr2 5 8 Round Head Square Neck Bolts
Specification
Carriage bolts (round head with a square neck) are commonly used in wood connections. The square neck under the round head will seat into the hole in the wood to prevent the head from turning. Because they are used with wood, carriage bolts are rarely high strength and virtually always supplied in a standard ASTM A307 specification.
Manufacturing
QBH Bolt manufactures carriage bolts from 1/2″ diameter through 1-1/4″ diameter in most ASTM and SAE specifications. Special tooling can be created to produce nonstandard head dimensions, carriage bolts larger than 1″ in diameter, or bolt heads with your company’s name and/or logo.
