Electro Hardware 1459M03F21-832 Hex Standoff 8-32

Product Description

The ELECTRO HARDWARE 1459M03F21-832 is a male-female hex circuit board standoff designed to create fixed spacing between PCBs, mounting surfaces, and chassis panels in electronic assemblies. Machined from brass with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff provides a corrosion-resistant, conductive connection point. The hex body measures 0.25 inches across flats, the overall length is 1.625 inches, and the body length is 1.25 inches. The male thread length is 0.375 inches and the female thread depth is 0.4375 inches, both cut to an 8-32 thread size. Installed by electronics technicians, assembly technicians, and field service pros working on control boards and panel assemblies.

This standoff is suited for use in residential and commercial electronic control assemblies, including HVAC control boards, relay panels, and general-purpose circuit board mounting applications. The male-female configuration allows boards to be stacked or mounted at a precise standoff height while passing a threaded connection through to the next layer. The hex body shape allows installation and removal with a standard hex wrench or nutdriver, making it practical in tight panel environments where finger-tightening is not feasible.

Key Features

• Male-female thread configuration for stackable or offset board mounting
• 8-32 thread size with 0.375-inch male thread length and 0.4375-inch female thread depth
• Brass construction with zinc-plated finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22
• Hex body profile across 0.25 inches for wrench or nutdriver installation
• Overall length of 1.625 inches with a body length of 1.25 inches for consistent board spacing
• Length tolerance held to plus or minus 0.005 inches for precise stacking assemblies

Compatibility

Designed as a standard inch-series male-female hex standoff for circuit board mounting applications requiring an 8-32 thread and 1.625-inch overall length.

Installation Notes

Installation and removal should be performed with the assembly de-energized and all power sources disconnected. Use a hex wrench or nutdriver sized to 0.25 inches across flats to avoid rounding the hex body. Thread engagement should be confirmed on both the male and female ends before final torque to prevent cross-threading. Follow applicable assembly standards and any relevant NEC or equipment manufacturer guidelines for control board mounting.
