✓Carriage Bolts are a robust and durable fastener solution. Carriage Bolts feature a square section underneath their head, which makes them self-locking when used within a square hole.
✓Precision forged, acid and alkali resistant, corrosion resistant and resistant to oxidation.The thread is smooth and flat, the squat is evenly stressed, and the screw teeth are stronger.
✓Carriage bolts are designed to fasten a wooden face to either wood or metal.Flat, smooth head eliminates the need for a washer.
✓Due to the head there is no groove type that can be used with a power assisting tool. It can also be hidden during actual use to prevent disassembly.
