Electro Hardware MMX1445M06-MSC Hex Standoff M3x0.5 25mm

Product Description

The ELECTRO HARDWARE MMX1445M06-MSC is a male-male hex circuit board standoff designed to create precise spacing between PCBs, panels, and chassis surfaces. Machined from aluminum alloy to Grade T-3, this standoff features an M3 x 0.5 thread on both ends and a hexagonal body that allows installation and removal with standard hex tooling. The overall length is 25 mm (approximately 0.984 inches), the body length is 25 mm, and the width across flats measures 5 mm (approximately 0.197 inches). A clear finish protects the aluminum surface. Electronics technicians, panel builders, and field service pros use this type of hardware in control board assemblies, enclosure builds, and rack-mounted equipment.

This standoff is suited for metric fastener applications requiring M3 x 0.5 male threading on both ends. Typical installations include mounting circuit boards inside HVAC control enclosures, electrical panels, and industrial equipment chassis. The hex body profile seats flush with standard wrenches or nut drivers, making it practical in tight board-level assemblies. Thread length is 5 mm on one end and 6 mm on the other, providing slight length variation that accommodates different mating-board thicknesses within the same assembly.

Key Features

• Male-male configuration with M3 x 0.5 threads on both ends for through-board standoff stacking
• Hexagonal body (5 mm width across flats) accepts standard hex wrenches and nut drivers
• Overall length of 25 mm with a length tolerance of -0.150 to 0.150 mm for precise board spacing
• Aluminum Grade T-3 construction — lightweight and corrosion-resistant
• Clear finish meets QQ-A-225A Comp 2 fastener standard
• Dual thread lengths (5 mm and 6 mm) to suit varied mating-surface depths

Compatibility

Designed as a metric M3 x 0.5 male-male hex standoff for use in circuit board assemblies, electrical enclosures, and panel-mounting applications where aluminum metric hardware is specified.

Installation Notes

Installation is typically performed by electronics technicians or panel builders. Power down all circuits and discharge any capacitors before working inside a control enclosure. Use a nut driver or hex wrench sized to the 5 mm across-flats dimension to avoid rounding the hex body. Do not overtighten — aluminum threads are susceptible to galling; hand-snug plus a quarter turn is standard practice for board-mount standoffs of this size class.
