Product Overview:
Double arming bolts are specialized fasteners typically made from galvanized steel, designed to bridge and secure two separate clamp connections. The term ‘double’ refers to their ability to connect and stabilize two points simultaneously. These bolts feature equal thread lengths at both ends with a raised, unthreaded center section where equipment can hang. They are essential in ensuring the structural integrity and stability of utility poles and other structural applications.
