Electro Hardware 1467M06F16-440 Hex Standoff 4-40

Product Description

The ELECTRO HARDWARE 1467M06F16-440 is a male-female hex circuit board standoff designed to mount and space printed circuit boards within electronic enclosures, control panels, and equipment chassis. Machined from aluminum with an anodized finish, it meets QQ-A-225A Comp 2 specifications. The standoff features a 4-40 unified thread on both the male and female ends and measures 1.6875 inches in overall length with a 0.25-inch width across flats. Electronics assembly technicians, control board fabricators, and panel builders install this fastener during board mounting operations where precise, repeatable standoff height and electrical isolation are required.

This standoff suits residential and commercial control panel assemblies, HVAC equipment circuit boards, and general electronic enclosure applications where a secure male-to-female threaded connection is needed to elevate a PCB from a mounting surface. The hex body shape allows engagement with standard nut drivers or hex wrenches, making it straightforward to install in tight board layouts. It is sold individually, with a minimum order quantity of 5 units.

Key Features

• Male-female thread configuration allows stacking or direct board-to-chassis mounting
• 4-40 unified thread size compatible with standard machine screw hardware
• Hex body profile accepts standard nut drivers and hex wrenches for easy installation
• Anodized aluminum construction provides corrosion resistance and electrical isolation
• Meets QQ-A-225A Comp 2 fastener standard for material and dimensional compliance
• Tight length tolerance of plus or minus 0.005 inches ensures consistent standoff height

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit board mounting applications requiring a 4-40 male-female hex standoff with a 1.6875-inch overall length and 0.25-inch across-flats hex body.

Installation Notes

Install and remove this standoff using a nut driver or hex wrench sized for the 0.25-inch across-flats hex body. De-energize all equipment and discharge any capacitors before performing circuit board mounting or service work. Follow applicable electrical codes and the equipment manufacturer's torque guidance for 4-40 fasteners. Avoid overtightening, which can strip the aluminum threads or crack the PCB mounting holes.
