Engineering Guide to Carriage Bolts
Carriage bolts feature a domed head and a square neck that prevents rotation, making them ideal for wood-to-metal connections.
Understanding the application
A carriage bolt has a rounded head and a square neck intended to engage a compatible opening.
Selection & technical considerations
The neck must seat correctly without damaging the mating part. Confirm available grip length, head clearance and washer arrangement.
Practical checks before use
Specify diameter, pitch, length, standard and finish. Installation should follow the joint specification rather than forcing an incorrect neck fit.
A complete enquiry includes
- Product type and reference standard or approved drawing
- Thread diameter, pitch, length and dimensional requirements
- Material, property class and specified surface finish
- Quantity, inspection documents and delivery destination
