Two-hole Lug Washer

August 6, 2015

The Bondwasher (BWUSA) for electrical bonding applications is available from Ingenuity Industries. The product features two holes in one continuous piece, designed to improve on the standard of using two separate washers with gaps between them. The product spreads the clamping force evenly between the lug and the ground bar, resulting in a uniform clamping force and a gas-tight seal. The clamping force is said to create an intimate electrical connection, resulting in the lowest-possible resistance between lug and ground bar. Low resistance and gas-tight seals also prevent corrosion between lug and bar. The product is designed to reduce the chances of passive intermodulation interference. It is made of 300-series stainless steel produced in conformance with the Defense Federal Acquisition Regulation Supplement. Using every hole in the ground bar allows the product to eliminate cutting or shaping of flat washers, and it also reduces the chances of flat washers rotating and loosening hardware over time. The product is approved by AT&T and Ericsson, among others. www.bondwasher.com
