Electro Hardware MMX1545M06-MSC Hex Standoff M3 X 0.5

Product Description

The ELECTRO HARDWARE MMX1545M06-MSC is a male-male hex circuit board standoff designed to create fixed spacing between PCBs, panels, and enclosures in electronic assemblies. Machined from Grade T-3 aluminum with a clear finish, this standoff features M3 x 0.5 threading on both ends and a hexagonal body that measures 6 mm across flats. The 25 mm overall length accommodates standard board-to-board stacking requirements. Thread length ranges from 8.5 mm to 9.5 mm. The lightweight aluminum construction keeps system weight low while providing reliable mechanical support in control boards, electronics enclosures, and instrumentation panels.

This standoff is suited for use in electronic and electrical control assemblies where metric hardware is specified. Common applications include mounting printed circuit boards inside HVAC control enclosures, electrical panels, and industrial equipment housings. The hexagonal body allows for wrench engagement during installation and removal, making it well-suited for service environments where standoff replacement or board repositioning is routine. Its aluminum construction is appropriate for indoor, non-corrosive environments.

Key Features

• Male-male thread configuration — M3 x 0.5 on both ends for through-stacking assemblies
• Hexagonal body, 6 mm width across flats, allowing standard hex tool engagement
• 25 mm overall length with thread length ranging from 8.5 mm to 9.5 mm
• Grade T-3 aluminum construction with clear finish
• Meets QQ-A-225A Comp 2 fastener standard
• Length tolerance held to -0.150 mm to 0.150 mm for precise board spacing

Compatibility

Designed as an OEM-style metric standoff replacement for circuit board assemblies requiring M3 x 0.5 male-male hex standoffs with a 25 mm overall length.

Installation Notes

Installation is typically performed by electronics technicians or electricians during control board assembly or field service. Power down and de-energize all circuits before working inside any enclosure. Use an appropriately sized hex wrench or nut driver to seat the standoff without over-torquing, as aluminum threads can be damaged by excess force. Follow applicable NEC guidelines when installing hardware inside electrical enclosures.
