Fastener Solutions offers high-quality hanger bolts threaded at both ends: a lag screw thread at one end and machine screw thread on the other. They are designed for insertion into a pre-drilled hole and are ideal for overhead applications, such as suspending electrical wiring or sheet metal from wooden structures. To save both time and money, purchase these general-use bolts online before you get started on your next commercial or industrial project. Choose from our full line of bolts below.
