Electro Hardware MMF1319M06F16M3 Hex Standoff M3x0.5

Product Description

The ELECTRO HARDWARE MMF1319M06F16M3 is an aluminum male-female hex circuit board standoff designed to create precise spacing between PCBs, chassis panels, and mounting surfaces in electronic assemblies. It carries an M3 x 0.5 thread and measures 18.76 mm (0.739 inches) overall length with a hex body width across flats of 4.5 mm (0.177 inches). The standoff ships uncoated in a bright finish and meets the QQ-A-225A Comp 2 aluminum material standard. Electricians, electronics technicians, and panel builders use these fasteners when assembling control boards, relay panels, DIN-rail enclosures, and similar low-voltage equipment where repeatable PCB standoff height is required.

This standoff is suited for metric-threaded circuit board mounting applications in both commercial and industrial electronic assemblies. The male end threads into a tapped hole or nut on a mounting surface, while the female end accepts an M3 x 0.5 screw to secure the next board layer. Typical use cases include HVAC control board assemblies, electrical enclosure builds, and any panel layout requiring stacked or elevated PCB mounting. The T3 material grade aluminum construction keeps weight minimal while providing adequate strength for static-load fastening applications.

Key Features

• M3 x 0.5 thread on both male and female ends for standard metric PCB mounting
• Hex body profile at 4.5 mm width across flats allows torque with standard hex drivers or wrenches
• 18.76 mm overall length with a 14.00 mm hex body length provides consistent PCB standoff height
• Thread depth of 6.40 mm and thread length of 4.76 mm ensure adequate engagement on both ends
• Aluminum T3 grade construction, uncoated bright finish, meets QQ-A-225A Comp 2 material standard
• Length tolerance held to -0.150 to 0.150 mm for repeatable stack height in multi-board assemblies

Compatibility

Designed for use in any metric M3 x 0.5 threaded circuit board standoff application requiring a male-female hex configuration with a 4.5 mm hex body.

Installation Notes

Installation is performed by electronics technicians or panel builders. Always de-energize and discharge the assembly before installing or removing standoffs near live circuit boards. Use a hex driver or open-end wrench sized to 4.5 mm across flats to avoid rounding the hex body. Do not overtorque aluminum standoffs, as threads can strip; hand-tight plus a modest snug with a wrench is typically sufficient for static PCB mounting loads.
