Electro Hardware MP1029M19F16M3 Hex Standoff M3x0.5

Product Description

The ELECTRO HARDWARE MP1029M19F16M3 is a female hex circuit board standoff designed to separate and support PCBs within electronic enclosures and control assemblies. Machined from nylon with a plain, uncoated finish, this standoff accepts an M3 x 0.5 thread and provides a full 15 mm thread depth across its 15 mm overall length. The hexagonal body measures 6 mm across flats, allowing a standard wrench or socket to seat it securely. With a tensile strength of 16,500 psi and compliance to MIL-P-17091B, it is suited for control board installations in HVAC, electrical, and industrial panel applications where non-conductive hardware is required.

This standoff is used wherever circuit boards must be mounted with electrical isolation between the board and the mounting surface or adjacent board. Common applications include residential and light commercial HVAC control boards, variable frequency drive panels, relay boards, and general electronics enclosures. The nylon construction eliminates the risk of shorting traces or ground planes on sensitive PCBs, making it the appropriate choice when metal standoffs are not suitable.

Key Features

• Female M3 x 0.5 thread, fully threaded to 15 mm depth for maximum engagement
• Nylon construction provides electrical isolation and corrosion resistance
• Hexagonal body, 6 mm across flats, compatible with standard metric wrenches
• Tensile strength of 16,500 psi for reliable mechanical retention
• Meets MIL-P-17091B fastener standard
• Plain, uncoated finish suitable for cleanroom and sensitive electronic environments

Compatibility

Designed as a direct-fit replacement or new-installation standoff for any circuit board assembly using M3 x 0.5 metric fasteners requiring a 15 mm standoff height with a non-conductive hex body.

Installation Notes

Installation is performed by electronics technicians and control board service professionals using a 6 mm metric wrench or nut driver. De-energize and discharge all capacitors in the control panel before handling circuit boards or replacing standoffs. Avoid over-torquing nylon hardware, as the material can crack or strip threads under excessive force. Follow applicable NEC or equipment manufacturer guidelines for PCB mounting clearances.
