Choosing a Carriage Bolt Type

AFT is a trusted carriage bolt supplier for construction, OEM, and many other industries. Carriage bolts most commonly have a smooth, domed head with a square section underneath that pulls into the material to prevent spinning during installation. This feature allows for the bolt to be self-locking when installed through a square hole in a metal strap, or a round hole in most woods. It can be installed with a spanner or wrench. Shop AFT for a large selection of Metric and Inch carbon or stainless steel carriage bolts in sizes No. 10, 1/2", 1/4", 3/16", 3/4", 3/8", 5/16", 5/8" 7/16", 1 1/2". 

Depending on your application, we supply a wide array of materials and grades, such as hot dipped galvanized carriage bolts commonly used for outdoor furniture because of the thicker protective coating, Grade-5 and Grade-8 carriage bolts for greater load carrying capacity, or 316 stainless steel carriage bolts for greater corrosion resistance. When installing sheet metal, choose a round head, short neck carriage bolt as the standard size neck may create an obstruction. And, for soft, ductile metals, wood and plastics, the round head, ribbed neck carriage bolt may be your best option. As a carriage bolt supplier, AFT is always here to help, so if you don’t see the exact product or size you need, please contact us for assistance.
