Electro Hardware MMX1545M09MSC-1 Hex Standoff M5x0.8

Product Description

The ELECTRO HARDWARE MMX1545M09MSC-1 is a male-male hex circuit board standoff designed to create fixed spacing between PCBs, chassis panels, and electronic assemblies. Machined from Grade 18-8 303 stainless steel with a passivated finish, this standoff resists corrosion and maintains dimensional stability in both indoor and controlled-environment applications. The metric M5 x 0.8 thread runs on both ends, with a 25 mm overall length and a 6 mm hex body for wrench engagement. Thread length measures 10 mm on one end and 9 mm on the other (nominal 9.5 mm). It meets QQ-S-763 fastener standards. Electricians, electronics technicians, and panel builders use this hardware when assembling control boards, enclosures, and rack-mount equipment.

This standoff is suited for metric PCB mounting applications in residential and commercial control panels, electrical enclosures, and equipment racks. The hex profile allows standard wrench or socket installation in tight board-to-board or board-to-chassis configurations. Its stainless steel construction makes it appropriate for environments where mild moisture or chemical exposure is a concern, such as HVAC control cabinets or poolside equipment enclosures. Sold individually with a minimum order quantity of one.

Key Features

• Male-male configuration accepts mating female standoffs or hex nuts on both ends
• M5 x 0.8 metric thread on both ends for consistent metric assembly
• 6 mm hex body width allows wrench or socket installation
• Grade 18-8 303 stainless steel construction with passivated finish for corrosion resistance
• Meets QQ-S-763 fastener standard
• Length tolerance of -0.15 mm to 0.15 mm for precise stack height control

Compatibility

Designed for metric PCB and chassis mounting applications requiring M5 x 0.8 male-male hex standoffs with a 25 mm overall length.

Installation Notes

Install using a 6 mm wrench or socket; do not over-torque, as stainless fasteners are susceptible to galling if driven too aggressively. Power down and de-energize any control board or panel before installing or removing standoffs. Follow applicable electrical enclosure assembly practices per NEC guidelines when mounting control boards inside energized cabinets.
