Electro Hardware MP409M06F16M3 Female Hex Standoff M3

Product Description

The ELECTRO HARDWARE MP409M06F16M3 is a female hex circuit board standoff designed to create fixed spacing between a PCB and a mounting surface or between stacked boards. Machined from aluminum alloy to material grade T3, this fully threaded standoff accepts an M3 x 0.5 thread and provides a 5 mm thread depth throughout its 5 mm overall length. The hexagonal body measures 4.5 mm across flats, allowing a standard wrench or socket to torque the fastener precisely into position. The plain, bright uncoated finish is appropriate for applications where corrosion exposure is minimal. Electronics assembly technicians and PCB mounting professionals install these standoffs during board-level assembly in control panels, HVAC control boards, and industrial enclosures.

This standoff is suited for metric PCB mounting applications in residential and light commercial electronic assemblies. The M3 x 0.5 thread size is common across a wide range of control boards and enclosure hardware found in HVAC systems, electrical panels, and equipment requiring secure board-to-chassis separation. The compact 5 mm overall length makes it appropriate for tight board-stack configurations where minimal height clearance is required. Installation is typically performed during bench assembly or field replacement of control board assemblies.

Key Features

• Female hex body with M3 x 0.5 thread for precise metric PCB mounting
• 5 mm overall length with fully threaded 5 mm thread depth
• 4.5 mm hex width across flats for standard wrench engagement
• Aluminum construction, material grade T3, for lightweight rigidity
• Plain bright uncoated finish per QQ-A-225A Comp 2 material standard
• Compact form factor suited for tight board-stack and panel installations

Compatibility

Designed as an OEM-style metric standoff for PCB mounting applications requiring an M3 x 0.5 female threaded hex spacer with a 5 mm overall length.

Installation Notes

Installation is performed by electronics technicians or field service professionals during PCB assembly or control board replacement. Power down and de-energize the equipment fully before handling any circuit board hardware. Use a wrench or socket sized to 4.5 mm across flats to seat the standoff without over-torquing, which can strip the aluminum threads. Verify thread engagement depth and board clearance before final assembly.
