Electro Hardware MP415M19F16M3 Female Hex Standoff M3x0.5

Product Description

The ELECTRO HARDWARE MP415M19F16M3 is a female hex circuit board standoff designed to create fixed spacing between printed circuit boards or between a board and a mounting surface. Manufactured from nylon with a plain uncoated finish, this standoff accepts an M3 x 0.5 thread and provides a full 8 mm thread depth for secure engagement. The hex body measures 4.5 mm across flats for wrench installation. Its nylon construction makes it suitable for applications where electrical isolation between fastener and board is required. Licensed electricians, PCB assembly technicians, and electronics maintenance professionals install these standoffs during board mounting and enclosure assembly work.

This standoff is used in residential and commercial electronic control assemblies, HVAC control boards, electrical enclosures, and general PCB mounting applications. The metric M3 x 0.5 thread size is common in low-voltage control circuitry and compact electronic assemblies. The fully threaded female design allows a male-threaded fastener to engage from one end while the hex body is secured from the opposite side, enabling stacked or elevated board configurations. Its lightweight nylon body adds negligible mass to sensitive assemblies.

Key Features

• Female hex body with M3 x 0.5 thread for metric PCB mounting applications
• Full 8 mm thread depth provides complete fastener engagement throughout the standoff length
• Nylon construction provides electrical isolation between the board and mounting hardware
• 4.5 mm width across flats allows installation and removal with standard hex tooling
• Plain uncoated finish with no metallic coating to interfere with nearby circuitry
• Meets MIL-P-17091B standard for nylon plastic fastener quality and dimensional consistency

Compatibility

Designed as an OEM-style replacement or new-installation standoff for PCBs and control assemblies using M3 x 0.5 metric thread fasteners.

Installation Notes

Installation is performed by electronics technicians and electricians during board assembly or service. Power down and de-energize all circuits before installing or removing circuit board hardware. Use a hex driver or wrench sized to 4.5 mm across flats to avoid stripping the nylon hex body. Nylon standoffs should not be overtightened, as the material is subject to deformation under excessive torque.
