Is the sleeve anchor one piece or a combination of different hardware?
The sleeve anchor is made up of four parts: nut, washer, threaded stud and sleeve. The threaded stud is flared to a cone shape at one end and the rest of the stud is threaded. The sleeve is a tubular piece of steel that fits over the stud and expands when the stud is pulled up through it. These anchors come fully assembled and ready to use.
