With no predrilled mounting holes, these lugs are your go-to if you don’t know your screw distances yet, or if you’re using nonstandard screw sizes. Just drill holes where you need them and install with whatever screws work best for your application. Squeeze the barrel onto the wire with a compression tool for a permanent connection that stands up to heavy vibration, sudden shocks, and daily wear and tear. Compression lugs are a step up from set screw lugs when you need a physically strong connection, though set screw lugs attach to even larger wire.

The plastic insulation shrinks when heated to grip and seal the wire more tightly than other locking spade terminals. In addition to sealing out contaminants, the heat shrink distributes strain when the wire is pulled or under tension for long periods.

Flanged spade terminals are the easiest spade terminals to connect. The two forks slide past the screw then snap onto the shank, keeping the terminal aligned and secure without your help during installation. Attach your wire with a crimping tool to avoid a damaged barrel and loose connection.

Flanged spade terminals resist slipping and falling from control panels and other vertical surfaces. Even if the screw loosens, the flanges hang onto the screw head to maintain the connection. Attach your wire with a crimping tool to avoid a damaged barrel and loose connection.
