Electro Hardware MP441M06F16M2.5 Female Hex Standoff M2.5

Product Description

The ELECTRO HARDWARE MP441M06F16M2.5 is a female hex circuit board standoff designed to mount and space printed circuit boards within electronic assemblies and enclosures. Machined from aluminum alloy T3 to the QQ-A-225A Comp 2 fastener standard, this standoff features an M2.5 x 0.45 female thread with a 4.8 mm thread depth, a 21 mm overall body length, and a 4.5 mm hex width across flats. The plain, bright uncoated finish suits general-purpose electronic mounting applications. Electrical and electronics technicians, control panel builders, and board-level assembly techs install this hardware when building or servicing PCB assemblies that require defined board-to-chassis or board-to-board spacing.

This standoff is suited for residential and commercial control panel assemblies, HVAC control board mounting, and any application requiring metric M2.5 threaded spacers in aluminum. The hex body profile allows installation and removal with a standard wrench or hex driver, making it practical in tight enclosure layouts where hand-tightening alone is insufficient. Minimum order quantity for this item is 10 pieces per order, with individual package quantity of 1.

Key Features

• M2.5 x 0.45 female thread with 4.8 mm thread depth for secure board attachment
• 21 mm overall length provides consistent board standoff spacing
• 4.5 mm hex width across flats allows wrench or driver installation
• Aluminum T3 material — lightweight and corrosion-resistant for electronics enclosures
• Plain bright uncoated finish meets QQ-A-225A Comp 2 fastener standard
• Length tolerance of -0.13 to 0.13 mm for precise stacking and spacing

Compatibility

Designed as an OEM-style metric standoff for circuit board mounting applications requiring M2.5 x 0.45 female threaded hardware in aluminum construction.

Installation Notes

Install and remove using an appropriately sized hex wrench or nut driver sized for 4.5 mm across flats. De-energize all circuits and discharge any stored voltage before working on or near circuit boards. Avoid overtightening, which can strip the aluminum threads or stress the PCB mounting holes. Follow applicable electrical codes and the PCB assembly manufacturer guidelines for torque and mounting sequence.
