FAQ

How to install a carriage bolt

Simply insert the carriage bolt through a pre-drilled hole. The square section underneath the head locks into place, preventing the bolt from spinning. Secure the bolt with a hex nut and washer (both not included) using just a single tool, such as a wrench or socket for quick and efficient installation.

How to remove a carriage bolt?

To remove a carriage bolt, start by loosening the nut with a wrench or pliers. If the bolt head isn’t visible, you can use a bolt extractor or saw to cut through it. For rusted bolts, applying penetrating oil may help ease the removal process.
