• How do Carriage Bolts compare to other types of bolts?

  Carriage bolts have unique characteristics that distinguish them from other types of bolts, making them suitable for specific applications.

• Understanding Carriage Bolt Sizes

  Carriage bolt sizes refer to the diameter, length, and thread pitch of the bolt. The size needed depends on the thickness of the materials being fastened and the strength requirements of the joint.

• Carriage Bolt ‘Pitch’ or ‘Threads per Inch’

  The pitch or threads per inch (TPI) of a carriage bolt refers to the number of threads along a one-inch length of the bolt. This affects how the bolt engages with the nut and the material, impacting its suitability for different materials and strength requirements.

• Installation Guide for Carriage Bolts

  To install a carriage bolt, a hole is drilled through the materials to be fastened. The bolt is then inserted from the smooth head side, with a washer and nut on the other side. Tightening the nut pulls the square shank into the material, preventing the bolt from turning.

• Removing Carriage Bolts

  To remove a carriage bolt, you typically loosen and remove the nut from the opposite side. If the bolt is stuck or the head is damaged, specialized tools like vise grips or a bolt extractor may be required.

• Advantages of Carriage Bolts

  Carriage bolts offer a neat finish with their smooth, rounded heads, and the square shank under the head prevents the bolt from turning during tightening. They are easy to install and provide a measure of security due to their tamper-resistant head design.
