Coupling Nut 1/2"-13

The MIDWEST FASTENER CORP 03495 is a steel coupling nut with a zinc-plated finish. It features a 1/2"-13 thread size and an overall length of 1-3/4 inches. The nut is tapped from both ends to meet in the centre. It is designed to join two threaded rods or studs securely.

Zinc-Plated Steel Finish

The zinc plating provides a layer of corrosion resistance for the steel body. This helps protect the fastener in environments where moisture or humidity may be present. The coating maintains the thread integrity during assembly and use. No additional lubricants or coatings are included with the hardware.

For Rod Extension Jobs

This coupling nut suits maintenance crews, fabricators and DIYers needing to extend threaded rod assemblies. It works where a standard hex nut cannot bridge the gap between two male threads. Buyers requiring a through-hole nut or a different thread pitch should select another fastener. Applications needing stainless steel or higher-grade alloy strength are not served by this item.

Highlights

Questions about this item

Will the zinc plating on this 1/2"-13 coupling nut need replacement if used outdoors?

The zinc plating provides corrosion resistance for general use; in harsh outdoor environments it may eventually wear and require the nut to be replaced.

What is the first limit reached when this coupling nut joins two threaded rods under continuous load?

The limiting factor is the tensile strength of the steel nut and the mating 1/2"-13 threads, which will yield or strip before the 1-3/4 in length becomes an issue.

Does this steel coupling nut generate heat or noise when the connected rods vibrate all day?

The nut itself is a passive fastener; it produces no heat or noise, though vibration in the assembled rods may create sound at the joint.
