Electro Hardware P301M06F16440 Hex Standoff 4-40 3/8in

Product Description

The ELECTRO HARDWARE P301M06F16440 is a female hex circuit board standoff designed to create precise spacing between printed circuit boards and mounting surfaces. Machined from aluminum alloy to T3 temper grade and left with a bright, uncoated plain finish, this standoff uses a 4-40 female thread on a fully threaded body. The overall length is 0.375 inches, with a thread depth matching that full 0.375-inch body length. The hexagonal body measures 0.1875 inches across the flats, allowing standard hex tooling to seat and torque the fastener without slipping. This hardware is typically installed by electronics assembly technicians, PCB board-level service technicians, and industrial maintenance electricians.

This standoff is suited for use in control board assemblies, HVAC control panels, electronic enclosures, and similar applications where a threaded female receiver is needed to accept a machine screw from a mating board or panel. The inch-system threading and compact 3/8-inch profile make it a common fit in residential and light commercial electronic control assemblies. The aluminum construction keeps weight low while providing adequate mechanical integrity for low-vibration environments. Minimum order quantity is 25 pieces; each package ships as a single unit.

Key Features

• Female 4-40 fully threaded hex body with 0.375-inch thread depth for a secure mating screw engagement
• Hexagonal body shape at 0.1875 inches across flats allows standard hex wrench or nut driver installation
• Aluminum T3 material grade — lightweight and corrosion-resistant for control board environments
• Plain bright uncoated finish — no added coating to interfere with dimensional tolerances
• Meets QQ-A-225A Comp 2 aluminum bar and rod specification
• Length tolerance held to plus or minus 0.005 inches for consistent board-to-board spacing

Compatibility

Designed as an OEM-style replacement or assembly-build standoff for circuit boards and control panels using 4-40 inch-series machine screws with inch-system hex standoff hardware.

Installation Notes

Installation is performed with a hex wrench or nut driver sized for 3/16-inch across-flats hex hardware. Always de-energize the control board or panel assembly before installing or removing standoffs to prevent electrostatic discharge damage to sensitive components. Avoid over-torquing aluminum standoffs, as the material can strip or crack under excessive load. Follow applicable assembly standards and IPC guidelines for PCB mechanical mounting when using these fasteners in production or service applications.
