Choosing the Right Carriage Bolt
If quality and longevity are important to you when it comes to carriage bolts, then it would be wise to purchase carriage bolts made out of stainless steel. These bolts will be corrosion-resistant, scratch-resistant, and strong. If the bolt is going to be used in exterior applications, then another good choice is hot dipped galvanized steel, which will also be extremely resistant to corrosion. Having said that, if the carriage bolt is going to be submerged in water, then the best choice is undoubtedly stainless steel.
FAQs on Carriage Bolts
Here are the answers to some of the most commonly asked questions about carriage bolts:
⑴Do carriage bolts have shear strength?
Yes. All carriage bolts have certain amount of both tensile and shear strength, depending on the grade and material of the fastener. Stainless steel carriage bolts usually have a shear strength of around 90,000psi.
⑵What is the difference between a lag bolt and a carriage bolt?
A carriage bolt has a flat end, while a lag bolt has a pointed tip. The top of a carriage bolt has a square neck that resists turning once the bolt is fastened. The flat end means that a washer and nut are used to secure a carriage bolt. Lag bolts have wide threads and are most often used with wood. They can be screwed directly into the wood and do not require nuts to complete the assembly.
⑶Do you use a washer with a carriage bolt?
Yes. It is important to use washers with carriage bolts, as they prevent damage when you use the nut to pull the bolt through the material.
⑷How do you measure a carriage bolt?
It is important to remember that carriage bolts are measure along their entire length, right from underneath the head, including the square neck. Don’t make the mistake of measuring from under the neck - this is a common error.
