Electro Hardware P293M09F16440 Hex Standoff 4-40 1/4in

Product Description

The ELECTRO HARDWARE P293M09F16440 is a female hex circuit board standoff designed to create precise spacing between PCBs, chassis panels, and mounting surfaces in electronic assemblies. Machined from 303 stainless steel with a plain bright finish, this standoff accepts a 4-40 threaded fastener and provides a fully threaded interior through its 1/4-inch overall length. The hex body measures 3/16 inches across flats, allowing for standard hex driver or nut driver installation. It meets QQ-S-763 stainless steel fastener specifications and is suited for applications where corrosion resistance and dimensional accuracy are required.

This standoff is used in residential and commercial electronic control board assemblies, HVAC control panels, terminal boards, and general electronics enclosures where secure board-to-surface spacing is needed. Electricians, electronics technicians, and control board service professionals install these as OEM-style hardware components during board mounting, replacement, or panel fabrication. The compact 1/4-inch length is typical for tight-clearance PCB stacking applications.

Key Features

• Female 4-40 thread accepts standard 4-40 machine screws for secure board attachment
• Fully threaded interior with 1/4-inch thread depth for maximum thread engagement
• 303 stainless steel construction meets QQ-S-763 specification for corrosion resistance
• Hex body profile at 3/16 inches across flats allows positive torque with standard tooling
• Plain bright finish with no coating to interfere with electrical grounding contact
• Compact 1/4-inch overall length suited for tight PCB spacing and shallow standoff applications

Compatibility

Designed as a standard 4-40 female hex standoff for use in PCB mounting, electronic enclosures, and control panel assemblies requiring a 1/4-inch overall length hex standoff with stainless steel construction.

Installation Notes

Installation is performed by electricians or electronics technicians during control board mounting or panel assembly work. De-energize all circuits and discharge any capacitors before handling PCBs or control boards. Use a correctly sized hex driver or nut driver matching the 3/16-inch across-flats dimension to avoid rounding the hex body. Do not over-torque the standoff into tapped holes, as stainless steel fasteners in aluminum panels are susceptible to galling.
