Product Description
A carriage bolt is a type of threaded fastener designed to be used with wood, although specialized versions can be used to fasten metal components. Also known as plow bolts or coach bolts, carriage bolts can be found in many hardware stores in an assortment of lengths, diameters, and thread pitches. They are usually made from various types of steel for strength and durability, though other materials can be used to make them as well.
Design
The design of a carriage bolt includes a large round, domed head with an externally threaded bolt projecting from it. The head is typically at least twice the diameter of the bolt shaft, and usually does not have slots for a screwdriver or other driving device. Underneath the head, there is a square fitting that grips the wood as the bolt is placed and fastened, keeping it from twisting or turning and otherwise maintaining a snug fit. In a variation on the basic carriage bolt, the square fitting under the rounded head is replaced with ribbing that holds the bolt in place when it is used with other metal components. The length of the bolt itself will vary according to its intended use, as will the diameter of the bolt and bolt head, regardless of the type of materials being fastened.
Our MEGATRO Carriage bolts as follow:
Diameter: 1/4" to M16
Finish: Zinc coated
Grade: A
Head: Round
Length: 3/8" to 200mm
Material: Steel, copper and stainless steel
Type: Carriage Bolt
System of Measurement: Imperial (Inch)
Notes: Carriage bolts are pushed into a hole the same size as the shank and then hammered in the rest of the way, where the square shoulder locks it firmly in place. Used whenever a smooth finish surface is needed so that nothing becomes snagged on the fastener. Zinc plating, retards the corrosion rate in a normal atmosphere.
