Electro Hardware MP1023M19F16M4 Hex Standoff M4x0.7 Nylon

Product Description

The ELECTRO HARDWARE MP1023M19F16M4 is a female hex circuit board standoff designed to create fixed spacing between PCBs, mounting plates, and enclosure panels in electronic assemblies. Machined from nylon with a plain (bright, uncoated) finish, this standoff carries a fully threaded female bore at M4 x 0.7 pitch with a thread depth of 12 mm matching its 12 mm overall length. The hexagonal body measures 6 mm across flats, allowing installation and removal with a standard wrench or hex driver. Tensile strength is rated at 16,500 psi, consistent with the MIL-P-17091B standard to which this part is manufactured. Electronics assembly technicians, panel builders, and field service engineers use this fastener in low-voltage control boards, HVAC circuit board assemblies, and general electronic equipment.

This standoff is suited for metric-thread PCB mounting applications in both residential and commercial equipment. Common uses include securing control boards inside HVAC air handlers, furnace control compartments, and industrial enclosures where nylon construction is preferred for electrical isolation and corrosion resistance. The plain finish makes it compatible with clean, dry interior environments. Length tolerance is held to -0.13 to 0.13 mm, keeping board-to-board spacing consistent across multi-board assemblies. Sold individually per package; minimum order quantity is 10 units.

Key Features

• Female hex body accepts M4 x 0.7 threaded fasteners on both ends for secure PCB standoff mounting
• 12 mm overall length with fully threaded 12 mm thread depth for maximum thread engagement
• 6 mm width across flats for easy installation with standard metric wrenches or nut drivers
• Nylon construction provides electrical isolation and eliminates galvanic corrosion concerns
• Manufactured to MIL-P-17091B fastener standard
• Tight length tolerance of -0.13 to 0.13 mm ensures consistent board spacing in multi-layer assemblies

Compatibility

Designed as an OEM-style metric standoff for M4 x 0.7 threaded PCB mounting applications in electronic and electrical equipment assemblies.

Installation Notes

Installation is performed by electronics assembly technicians or qualified field service personnel. Always de-energize and discharge any circuit board assembly before removing or installing standoffs to prevent damage to sensitive components. Use a metric wrench or nut driver sized for 6 mm across flats - do not overtighten nylon standoffs, as excessive torque can crack the body or strip the threads. Verify thread engagement depth against the mating fastener length before assembly to ensure the board is seated and secured correctly.
