Electro Hardware 1467M03F21-440 Hex Standoff 4-40

Product Description

The ELECTRO HARDWARE 1467M03F21-440 is a male-female hex circuit board standoff designed to create fixed spacing between PCBs, panels, and chassis in electronic and control system assemblies. Machined from brass with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff provides corrosion resistance and reliable thread engagement in demanding environments. It features a 4-40 thread size, a 1/4-inch hex width across flats, an overall length of 1-11/16 inches (1.6875 inches), a body length of 1-1/2 inches, and a thread length of 3/16 inch on the male end with a 1/4-inch thread depth on the female end. The hex profile allows standard wrench or nut driver installation without slippage.

This standoff is suited for use in HVAC control boards, electrical enclosures, industrial control panels, and general PCB mounting applications. Electricians and electronics technicians install these fasteners when stacking or mounting circuit boards within equipment cabinets, replacing worn or stripped standoffs during board-level service, or assembling new control panel builds. The inch-system sizing and 4-40 thread make it a standard fit across a wide range of light-duty electronic hardware applications.

Key Features

• Male-female hex design allows stacking or panel-mount configurations
• Brass construction with zinc-plated finish per ASTM B633 Type 1 and QQ-B-626 Comp 22
• 4-40 thread size for compatibility with standard #4 hardware
• 1/4-inch hex width across flats accepts standard nut drivers and wrenches
• Overall length of 1.6875 inches with a 1-1/2-inch body length for defined board spacing
• Length tolerance of -0.005 to 0.005 inches for precise fitment

Compatibility

Designed as a standard inch-system male-female hex standoff for circuit board and panel mounting applications using 4-40 threaded hardware.

Installation Notes

Install and remove using a nut driver or open-end wrench sized to 1/4-inch across flats. Always de-energize and discharge any board or assembly before servicing electronic hardware. Avoid over-torquing brass standoffs, as the material is softer than steel and threads can be damaged by excessive force. Follow applicable NEC guidelines and equipment manufacturer service procedures when working inside energized enclosures.
