Hillman Steelworks N182-675 Coupling Nut, Zinc, 5/16 In.-18 Unc

A coupling nut is a threaded fastener designed to join two pieces of threaded rod end-to-end. This zinc-plated steel coupling nut connects threaded rods securely in a wide range of fastening applications, from wagon axles and carts to general do-it-yourself projects. The zinc coating provides protection against rust and wear.

The 5/16 In.-18 UNC coarse thread sizing makes this coupling nut compatible with standard threaded rod. The design includes visible witness holes that allow you to confirm both rods are fully engaged and threaded together completely before final tightening. This coupling nut works equally well in vertical, horizontal, left or right hand applications, making it highly adaptable to different assembly orientations and project requirements.
