timber joint connector

timber connector

One of a number of metal connectors used (with bolts) to join timber in heavy construction; usually the connector has a series of sharp teeth which dig into the wood as a bolt is tightened, thereby preventing lateral movement and decreasing the number of bolts required; another type employs a sharp round ring to perform this function.
