Electro Hardware MMX1415M09-MSC Hex Standoff M3 X 0.5

Product Description

The ELECTRO HARDWARE MMX1415M09-MSC is a male-male hex circuit board standoff designed to create fixed spacing between PCBs, mounting panels, and enclosure surfaces. Threaded M3 x 0.5 on both ends, this standoff accepts standard M3 fasteners for secure, tool-assisted assembly. The hex body measures 5 mm across flats, providing positive wrench engagement during installation. Overall length is 10 mm, with a body length of 10 mm and thread lengths of 5 mm and 6 mm on opposing ends. Manufactured from Grade 18-8 303 stainless steel with a passivated finish, the part meets QQ-S-763 specification requirements. Electronics assemblers, panel builders, and field service technicians install these standoffs in control boards, enclosures, and rack-mount assemblies.

This standoff is suited for metric-threaded circuit board mounting applications in electronic enclosures, industrial control panels, HVAC control boards, and similar equipment requiring precise board-to-surface clearance. The M3 x 0.5 thread size is widely used in compact electronic assemblies. The passivated stainless steel construction resists corrosion in light-moisture and general-purpose indoor environments, making it appropriate for both OEM manufacturing and field repair work where a durable, corrosion-resistant fastener is required.

Key Features

• Male-male threaded ends, M3 x 0.5, accept standard M3 hardware on both sides
• Hex body shape, 5 mm across flats, allows positive wrench or nut-driver engagement
• Grade 18-8 303 stainless steel construction for corrosion resistance and mechanical strength
• Passivated finish per QQ-S-763 specification for enhanced surface protection
• 10 mm overall length with thread lengths of 5 mm and 6 mm on opposing ends
• Metric measurement system — direct fit for M3-threaded PCB and panel assemblies

Compatibility

Designed as an OEM-style replacement or service standoff for metric M3 x 0.5 threaded circuit board mounting applications in electronic control assemblies and panel enclosures.

Installation Notes

Installation is typically performed by electronics assemblers, panel builders, or field service technicians. Power down and de-energize all control boards and enclosures fully before removing or installing standoffs. Use an appropriately sized metric hex driver or wrench on the 5 mm across-flats body to avoid deforming the hex. Avoid over-torquing stainless steel fasteners, as galling can occur — apply consistent hand-tight force with a tool rather than power-driving.
