Clamp-On Wire Splicing Connectors
Press down on the clamp to connect wires and pull it up to disconnect.
Clear connectors let you see that the wire is inserted properly and stripped to the correct length. They have two test slots—one on the front and one on the back—to test voltage even after the connectors are installed. Use a DIN rail adapter (sold separately) to mount these connectors to a 35 mm DIN rail.

Handle Nuts
Use these handles for quick assembly and disassembly. Their offset grip provides leverage, making them a good alternative to wing nuts. Long shafts can thread through these handles for mounting versatility.
Iron handle nuts with a zinc-plated finish have corrosion resistance.
Steel handle nuts are stronger than iron.
Stainless steel handle nuts have excellent corrosion resistance, making them the best choice for harsh environments. They also have good chemical resistance.

Acme Lead Screws and Nuts
Found in hand-powered clamps, vises, grates, doors, and work tables, lead screws and nuts have broad, square threads that are well suited for quick assembly, high clamping forces, and lifting and lowering heavy objects. To ensure compatibility, please select components that have the same thread direction and size.
Cast iron components have good machinability and high strength.
Travel distance per turn, also known as screw lead, is the distance a nut or handle moves with one revolution of the lead screw.
For technical drawings and 3-D models, click on a part number.
Thumb nuts fasten and position lead screw components. Thumb nuts are easy to grip and tighten by hand for quick assembly and disassembly.
Handles fasten and position lead screw components. Handles are easy to grip and tighten by hand for quick assembly and disassembly.
