Products Description
Rail bolts, also known as rail bolts or rail anchor bolts, are used to secure rails or base plates to sleepers. Rail bolts are bolts that are inserted into holes in the sleepers and have a funnel nut that bites into the underside of the sleeper.
Rail bolts are usually made of high-strength materials, such as carbon structural steel, alloy structural steel, etc. In order to meet different usage requirements, the strength grades of bolts are also different. Common ones are 8.8 grade and above high-strength bolts, and even higher strength bolts are used in key connection parts.
