Electro Hardware MP1043M19F16M3 Hex Board Standoff M3

Product Description

The ELECTRO HARDWARE MP1043M19F16M3 is a female hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. Machined from nylon with a plain, uncoated finish, this standoff accepts M3 x 0.5 thread and runs fully threaded through its 22 mm overall length, giving the full thread depth for secure fastener engagement on both ends. The hexagonal body measures 6 mm across flats, allowing standard hex drivers for consistent installation torque. Licensed electronics technicians, control board assemblers, and field service techs working on HVAC controls, industrial panels, and similar low-voltage electronics will find this standoff a direct match for metric PCB mounting applications.

This standoff is suited for residential and commercial electronic control assemblies where nylon construction is required to provide electrical isolation between the board and chassis. Common applications include HVAC control board mounting, industrial relay panel assembly, and any metric PCB stack where a non-conductive, corrosion-resistant spacer is needed. The M3 x 0.5 thread size is a widely used metric fastener standard in printed circuit board hardware. Material grade 101 nylon meets MIL-P-17091B specifications, making it appropriate for assemblies requiring documented material compliance.

Key Features

• Fully threaded female design with 22 mm thread depth for maximum fastener engagement
• Nylon construction provides electrical isolation and corrosion resistance
• 6 mm hex body width across flats allows standard hex driver or wrench installation
• MIL-P-17091B compliant material grade 101 nylon for documented specification traceability
• Plain, uncoated bright finish suitable for non-conductive PCB spacer applications
• Length tolerance of -0.13 to 0.13 mm for consistent board standoff height in stacked assemblies

Compatibility

Designed as an OEM-style metric PCB standoff for use with M3 x 0.5 fasteners in circuit board mounting applications requiring a nylon, electrically isolating hex spacer.

Installation Notes

Installation is typically performed by electronics technicians or control board service professionals. Power down and de-energize all circuits before handling or replacing PCB hardware. Use an appropriately sized hex driver or nutdriver sized for 6 mm across flats to avoid deforming the nylon body. Do not over-torque nylon standoffs, as the material will crack or strip threads under excessive load.
