Electro Hardware 1459M06F16-440 Hex Standoff 4-40

Product Description

The ELECTRO HARDWARE 1459M06F16-440 is a male-female hex circuit board standoff designed to create precise spacing between PCBs or mount circuit boards to a chassis. It is machined from 6061-series aluminum (T-3 material grade) with an anodized finish for corrosion resistance and surface durability. The threaded configuration features a 4-40 male thread on one end and a 4-40 female thread on the other, with an overall length of 1.4375 inches and a hex body width across flats of 0.25 inches. Electronics assembly technicians and electrical panel builders install this standoff using standard hex drivers or wrenches during PCB stackup and enclosure mounting operations.

This standoff is suited for use in electronic enclosures, control panels, and PCB assemblies across commercial and industrial applications. The 1-7/16 inch overall length and 1-1/4 inch body length provide clearance for component clearance or stacking multiple boards. The anodized aluminum construction makes it appropriate for environments where weight savings and conductivity isolation are priorities. It is commonly installed by electrical or electronics assembly technicians working on control systems, automation panels, or general electronics packaging.

Compatibility

Designed as an OEM-style replacement or new-installation standoff for 4-40 threaded PCB mounting applications in electronic assemblies and control enclosures.

Installation Notes

Installation requires a hex driver or wrench sized for 1/4 inch width across flats. Ensure the mating board holes are properly aligned before torquing to avoid thread cross-loading. De-energize all circuits and discharge any stored energy before working inside panels or enclosures. Follow applicable NEC requirements when installing standoffs inside electrical enclosures.
