Product Description
The Hillman 881654 is a high-strength industrial fastener designed to extend threaded rod assemblies or join two male-threaded components. This elongated hexagonal nut acts as a bridge, allowing you to connect multiple 5/8-inch coarse threaded rods into a single, continuous length for structural supports, hanging fixtures, or mechanical repairs.
Engineered for durability, this coupler features a zinc-plated finish that provides moderate corrosion resistance, making it suitable for interior projects or protected exterior applications. Its standard hex geometry ensures a secure grip for wrenches during high-torque installations.
