Electro Hardware MP1041M19F16M4 Female Hex Standoff M4

Product Description

The ELECTRO HARDWARE MP1041M19F16M4 is a female hex circuit board standoff designed to create precise spacing between PCBs and mounting surfaces in electronic assemblies. Made from nylon with a plain, uncoated finish, this standoff features a fully threaded M4 x 0.7 metric thread with a 21 mm thread depth equal to its overall length. The hex body measures 6 mm across the flats, allowing installation and removal with standard nut drivers or hex wrenches. With a tensile strength rated at 16,500 psi, this fastener meets the MIL-P-17091B military specification for plastic fasteners. It is suited for electronics technicians, PCB assembly technicians, and enclosure builders working in both commercial and industrial environments.

This standoff is used in circuit board mounting applications where metal-to-board contact must be avoided or where electrical isolation between the board and chassis is required. The nylon construction makes it appropriate for environments sensitive to corrosion or where non-conductive fasteners are specified by design. Typical install scenarios include control board assemblies, panel enclosures, and rack-mounted electronics in HVAC controls, industrial controls, and general electronic equipment.

Key Features

• M4 x 0.7 fully threaded female hex standoff with 21 mm overall length and 21 mm thread depth
• Nylon construction provides electrical isolation and corrosion resistance
• 6 mm width across flats allows use with standard nut drivers and hex wrenches
• Plain, uncoated finish - no added coating that could affect dielectric properties
• Meets MIL-P-17091B fastener standard for plastic hardware
• Length tolerance of -0.13 to 0.13 mm supports precise board spacing

Compatibility

Designed for use in M4-threaded circuit board mounting applications requiring nylon hex standoffs with a 21 mm OAL and 6 mm hex body width, conforming to MIL-P-17091B.

Installation Notes

Installation is performed by electronics technicians or enclosure assembly personnel. Power down and de-energize all circuits before installing or removing standoffs from a live board assembly. Use a nut driver or hex wrench sized to 6 mm across the flats - avoid over-torquing nylon hardware, as it is subject to thread stripping at excessive force. Mating screws or standoffs must be M4 x 0.7 metric thread to ensure proper engagement.
