The GI Long Nut - DIN 6334, is a high-precision threaded coupling used for extending threaded rods or connecting bolts in tension applications. Its elongated hexagonal body ensures a stable grip for wrenches, while the galvanized finish provides basic corrosion protection for indoor and light outdoor use. This nut type is ideal for structural supports, conduit systems, rigging, and HVAC installations where threaded rod joining is required.
Made from galvanized iron, these long nuts are designed for medium-load applications where extended thread length is necessary. Commonly referred to as coupling nuts or extension nuts, they are essential in industrial, commercial, and mechanical applications where alignment or extended reach is needed.
- Used for joining two threaded rods in construction scaffolding and framing
- Ideal in electrical and HVAC installations for hanging threaded systems
- Frequently used in suspended support systems and bracing structures
- Also suitable for mechanical assemblies that require repositionable rod connections
- A popular choice for maintenance, repair, and extension tasks
