  Carriage Bolts   A307A F1554 A449 A354 F593 SAE J429   Carriage Bolts (round head with 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   Jinrui mufactures carriage bolts from 1/2" diameter through 1-1/4" diameter in most ASTM, AASHTO, 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.   Standard Thread Length   Bolt lengths ≤ 6": Thread length = (2 X diameter) + 1/4"
Bolt lengths > 6": Thread length = (2 X diameter) + 1/2"   Note: Most stock carriage bolts have extended thread length.   Stock   Diameters: 3/8" - 3/4"
Lengths: 18" maximum
Origin: Import
Finish: Black and hot-dip galvanized   Dimensions
