Midwest Fasteners Zinc Plated Steel Coarse Thread Coupling Nut

Midwest Fasteners Zinc Plated Steel Coarse Thread Coupling Nut

Midwest Fasteners zinc plated steel coupling nuts join two lengths of threaded rod or all-thread into one continuous run, letting fabricators and maintenance techs extend rod length without re-cutting or re-threading. Machined from steel and finished in zinc plating for corrosion resistance on jobsite and shop applications, this coupling nut family carries a coarse (NC) thread pitch and is available in sizes from 1/4-20 through 3/4-10, including 3/8-16, 1/2-13, 5/8-11, 10-24, and reducing couplings such as 3/8-16 to 1/4 and 3/8-16 to 1/2, so the correct size can be matched to the threaded rod on hand. Each size features an elongated hex body that provides extra thread engagement on both ends compared to a standard hex nut, giving a secure, properly seated connection when splicing threaded rod runs for overhead support, equipment mounting, or structural bracing work.

Key Features

• Size Range: Available in 1/4-20, 3/8-16, 3/8-16 to 1/4, 3/8-16 to 1/2, 1/2-13, 5/8-11, 3/4-10, and 10-24 to match a wide range of threaded rod diameters.
• Material & Finish: Steel construction with a zinc plated finish for added corrosion resistance over bare steel.
• Thread: Coarse (NC) thread pitch for easy starting and general-purpose rod coupling.
• Type: Coupling nut design allows two pieces of threaded rod to be joined into one continuous length, including reducing options that join two different rod diameters.
• Hex Body: Extended hex length provides greater thread engagement than a standard hex nut for a more secure splice.

Why Midwest Fasteners?

Midwest Fasteners builds its coupling nuts from steel with a zinc plated finish for dependable corrosion resistance, and holds each NC thread size to consistent, accurate tolerances so every size mates cleanly with its matching threaded rod every time. That consistency in size, material and finish is what contractors and maintenance techs need when a threaded rod splice has to hold up on a jobsite or in an equipment room, whether joining two identical rod diameters or using a reducing coupling between two different sizes.
