1/2''-13 Zinc-Plated Coupling Nuts
These 50-piece coupling nuts suit maintenance crews and fabricators who need to join threaded rod or extend studs on the job site. The coarse 13 threads per inch match standard UNC hardware so the nuts thread on quickly with common tools. Zinc plating adds a layer of corrosion resistance for indoor and sheltered outdoor assemblies.
Bulk pack reduces reorder frequency
The 50-count box keeps a ready supply at the bench or in the service truck so technicians avoid mid-job trips to the supply house. Manufacturer-direct shipment on qualifying orders means the stock arrives in original packaging without extra handling. Having the full quantity on hand speeds repetitive coupling tasks across multiple workstations.
1-1/4 inch length sets the engagement window
Each nut provides a fixed 1-1/4 inch thread depth that determines how much rod or stud can be joined in a single connection. Builders who need longer engagement must select a different coupling nut length. The dimension is fixed by the RC3 specification and cannot be altered in the field.

Questions about this item
How often will the zinc plating on these 1/2''-13 steel coupling nuts need inspection or replacement?
The zinc plating resists corrosion under normal conditions; inspect periodically for white rust or red rust and replace any nuts showing significant coating loss.
What is the first limit reached when these coupling nuts are used continuously in a vibrating assembly?
The 1/2''-13 thread engagement and zinc coating integrity are the primary limits; sustained vibration can loosen threads or accelerate plating wear before the steel yields.
How much heat do these 50 coupling nuts generate when installed in a system running all day?
These are passive steel fasteners; they generate no measurable heat during operation regardless of how long the system runs.
