Introduction
COACH BOLT As per DIN - 603 / IS-2609
A carriage bolt is a type of fastener that has a rounded head and a square neck under the head. It is designed to be inserted through a hole in one piece of material and tightened into place using a nut. The square neck of the carriage bolt helps to prevent the bolt from turning when the nut is tightened. Carriage bolts are commonly used in woodworking and construction applications to secure two pieces of wood or other materials together. They are available in a variety of materials, including steel, stainless steel, and brass, and in a range of sizes and grades to meet different strength and corrosion resistance requirements. Carriage bolts are often used in conjunction with a washer and a nut to provide additional support and to distribute the load evenly.
