Stainless Steel A4 - 70 Plain Color 1/2 " Coulping Hex Head Nuts for Agricultural Electronics

1. Product Description

Hex coupling nuts or extension nuts as they are often referred offer an extended female threaded nut to allow two male threaded screws to be joined together.

Materials include: Chemically blacked steel and 316 stainless steel

Coupling nut dimensions are described by the Industrial Fasteners Institute in standard IFI-128. Chemical and mechanical properties are controlled in conformance with ASTM and SAE nut specifications (ASTM A563, ASTM A194 and SAE J995).

Standard threads are UNC 2B, RH, with other thread series and profiles available by special order. Hot dip galvanized coupling nuts are normally tapped oversize after galvanizing to accommodate the zinc coating on the rod threads. Coupling nuts up to 1-1/2" thread size are tapped all the way through from one end, allowing them to be completely threaded on to one of the members which are to be coupled, a feature that is required for certain assembly situations. Coupling nuts larger than 1-1/2" thread size cannot be tapped all the way through without special extended length taps and are therefore furnished with RH/RH threads (tapped to a depth of L/2 from each end) unless specifically ordered as 'threaded all the way through'.

Coupling nuts can also be threaded with two different thread sizes or profiles. These parts are normally identified as 'reducing coupling nuts'.

Refer to the coupling nut table for dimensions. Some of the sizes listed in this table have an 'Across Flats Size' slightly larger than that called for by IF-128 due to commercial availability of hexagon bar stock. Because of limited availability of hex stock larger than 3-1/2", coupling nuts with thread sizes 2-1/2" and larger are usually made from round bar. These larger parts can be provided with milled wrench flats or a milled hes.

3.Application

These are used to make up long rod assemblies from shorter lengths of rods. The rods are threaded into the coupling nut for a certain distance. It is given a plain finish.

Coupling nuts can be used to tighten a rod assembly inward or to press a rod assembly outward.

Coupling nuts are used to make up long tie rod assemblies from shorter lengths of rod and to facilitate assembly of two fasteners or fittings which each have external threads.
