HARDWARE DATA (continued)

Recommended Clamping on Bolted Connectors:

When installing a bolted connector, an appropriate sequence needs to be followed. INSTALLATION INSTRUCTIONS:

1. Nuts need to be tightened up to 30% of expected torque. 2. A check needs to be done to ensure the clamping elements are even.

3. Tightening has to follow a sequence (1-6) as shown below. As a general rule, the torque has to be applied to the nut. For ease of installation most connectors are designed for one wrench installation. A torque wrench is recommended when tightening the nut to ensure the proper torque is applied.

BURNDY offers three sizes of professional grade torque wrenches, catalog number BTW30150 to be used on connectors requiring 30-150 in-lbs., the BTW150750 , designed for 150-750 in-lbs., and the BTW1575F12 , designed for 15 - 75 ft-lbs. These micro adjustable “click-type” torque wrenches feature an easy-to-read scale that can be easily matched to the recommended torque of each of our mechanical connector products. Calibration traceable to N.I.S.T.
