Electro Hardware MP1039M19F16M4 Hex Standoff M4 Nylon

Product Description

The ELECTRO HARDWARE MP1039M19F16M4 is a female hex circuit board standoff designed to create precise spacing between PCBs, mounting plates, and enclosure panels. Machined from nylon with a plain uncoated finish, this standoff features a fully threaded interior with an M4 x 0.7 thread size and a 20 mm thread depth, providing reliable engagement across the full length of the fastener. The hex body measures 6 mm across flats, allowing standard hex drivers to seat and torque the standoff without slippage. At 20 mm overall length, it is suited to applications requiring a consistent, electrically non-conductive standoff in control boards, PCB assemblies, and electronic enclosures. Electronics assembly technicians and field service technicians commonly install this type of hardware during board mounting and panel fabrication work.

This standoff is used in metric PCB mounting applications where electrical isolation between the board and the mounting surface is required. Its nylon construction makes it appropriate for residential and commercial electronic equipment, control panel assemblies, HVAC control boards, and industrial enclosures. The plain finish and MIL-P-17091B rating indicate conformance to established military and commercial fastener standards, making it a recognized choice for both OEM manufacturing and field replacement work.

Key Features

• M4 x 0.7 female thread, fully threaded to 20 mm depth for maximum engagement
• Hexagonal body at 6 mm across flats for wrench or hex driver installation
• Nylon construction provides electrical isolation between the PCB and mounting surface
• Plain uncoated finish resists interference with sensitive electronic components
• Meets MIL-P-17091B fastener standard
• Tensile strength rated at 16,500 psi for structural integrity under normal board-mounting loads

Compatibility

Designed as an OEM-style replacement or new-installation standoff for metric M4 threaded PCB mounting applications requiring a nylon hex spacer.

Installation Notes

Installation is performed by electronics assembly technicians or qualified service personnel. Power down and de-energize all circuits before handling PCBs or replacing standoffs in live enclosures. Use a hex driver or open-end wrench sized for 6 mm across flats. Avoid over-tightening nylon hardware, as nylon threads can deform under excessive torque; snug to contact and confirm seating without stressing the PCB.
