Double Arming Bolts

Double arming bolt is also called double threaded bolt, double ended bolt, or DA bolt. According to the length of the thread, the double arming bolts include all thread bolts and double threaded bolts.

The double ended bolts are widely used on the pole line and cross arm construction. As all thread bolts go through the pole, the two ends of the double arming bolt will be locked and secured by nuts and washers. At the same time, one end of the double arming bolt will connect with eye nuts for dead-end application.

Each double arming bolt is assembled with four square nuts or hex nuts according to the requirements of the customer. All the double ended bolts have semi-cone points or chamfered round end. The cone points at both ends of the double arming bolt help to drive and remove it from the pole easily without damage to the thread. The double arming bolt length is measured from the last thread, end to end without the length of the cone. The widely used double arming bolt diameter is 5/8, 3/4 and 1/2 inch with different lengths

They are Hot Dip Galvanized with full rolled threads. Each bolt is furnished with Four Square Nuts.
