Insulated Ring Terminals
Standard Ring Terminals—Straight
A plastic cover insulates the barrel to prevent short-circuiting with nearby wire. Mount these terminals on a threaded screw or stud for a more secure connection than spade and hook terminals. Use a crimper (not included) to install wire.
Nylon-insulated terminals are more durable and resist chemicals better than vinyl-insulated terminals.

Insulated High-Temperature Ring Terminals
With a heat-resistant PVDF cover on the barrel, these terminals are best for high-temperature applications where you want to prevent short-circuiting with nearby wire. Mount them on a threaded screw or stud for a more secure connection than spade and hook terminals. Use a crimper (not included) to install wire.

Compression Lugs
1 Hole—90° Elbow
Use a compression tool to attach lugs to wire. Mount them to a screw.
Copper lugs can be used in large power distribution systems, motors, and generators.
90° elbow lugs connect to wire at a right angle, so they fit in tight spaces.
