Electro Hardware MP415M06F16M3 Hex Board Standoff M3

Product Description

The ELECTRO HARDWARE MP415M06F16M3 is a female hex circuit board standoff machined from aluminum alloy and designed to create precise spacing between PCBs, chassis panels, and mounting surfaces. The standoff features an M3 x 0.5 female thread that runs the full 8 mm thread depth, providing maximum thread engagement for reliable fastener retention. The hexagonal body profile measures 4.5 mm across flats, allowing standard hex tooling to seat and torque the standoff without slipping. With an overall length of 8 mm and a plain, bright uncoated finish, this part suits both prototype builds and production assemblies where anodized or plated surfaces are not required. Licensed electricians, electronics technicians, and field service engineers install these fasteners during control board mounting and enclosure assembly work.

This standoff is suited for metric-threaded circuit board mounting applications in residential and commercial control panels, industrial enclosures, and electronic equipment chassis. It is a common hardware item in HVAC control board assemblies, electrical panel builds, and instrumentation enclosures where M3 metric fasteners are specified. The compact 8 mm overall length and hex body make it well suited to tight board stacking configurations where controlled standoff height and easy installation with a nut driver or hex wrench are priorities.

Key Features

• M3 x 0.5 fully threaded female thread with 8 mm full-depth thread engagement
• Hexagonal body, 4.5 mm width across flats, compatible with standard metric hex tooling
• Aluminum construction, Material Grade T3, per QQ-A-225A Comp 2 specification
• Plain bright uncoated finish suitable for general indoor electronic assembly
• Overall length of 8 mm with a length tolerance of -0.13 to 0.13 mm for precise board spacing
• Lightweight at approximately 0.001 pounds per piece, minimizing added load on PCB assemblies

Compatibility

Designed as a metric M3 x 0.5 female hex standoff for use in circuit board mounting applications where an 8 mm overall length and aluminum construction are specified.

Installation Notes

Installation is typically performed by electronics technicians or licensed electricians during control board assembly or enclosure builds. Always de-energize and lock out the equipment before servicing any circuit board or panel assembly. Use an appropriately sized metric hex nut driver or wrench sized for 4.5 mm across flats to seat the standoff without deforming the hex body. Do not overtighten into threaded inserts or PCB mounting holes, as aluminum threads can be damaged by excessive torque.
