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.

These terminals grip the wire more tightly and are easier to install than other locking spade terminals. A combination of crimping, heat shrink, and solder makes the wire extra rigid and secure. First, squeeze the barrel onto the wire so it stays put when tugged, vibrated, or under tension for long periods. (Use a crimping tool to avoid a damaged barrel and loose connection.) When you apply heat, the plastic seals and grips the stranded wire while the enclosed solder melts it into a solid, rigid wire that's even tougher to twist or bend.

Spade terminals are faster to install than ring terminals because they don't require you to remove the screw from the terminal block or other connection point.
