Compression Lugs

Available148 products

Compression lugs create permanent connections between industrial cables and connection points using bolts and nuts. Also known as compression connectors, they're used to supply power or ground in applications where reliability or continuous vibration are a concern, such as automobiles, transformers, appliances, and electrical panels. They have barrel-shaped bodies that compress the conductor to create a tight bond and flat or angled tongues (or pads) with mounting holes that fasten around threaded studs or bolts. One-hole compression lugs have a single mounting hole, while two-hole compression lugs have two mounting holes to prevent the lug from turning if the connection becomes loose. Their bodies have color-coded bands and markings that identify where to compress and which die component and tool are necessary to create a solid, uniform bond between the cable and connector.
