Electro Hardware MP419M03F21M2.5 Female Hex Standoff M3x0.5

Product Description

The ELECTRO HARDWARE MP419M03F21M2.5 is a female hex circuit board standoff designed to create fixed spacing between PCBs and mounting surfaces in electronic assemblies. Machined from brass with a clear zinc chromate (zinc-plated) finish per ASTM B633 Type 1 and QQ-B-626 Comp 22, this standoff features an M3 x 0.5 fully threaded female thread running the full 10 mm thread depth. The hex body measures 6 mm across flats for clean wrench engagement. At 10 mm overall length with a 4 mm body length, it suits compact board-to-board and board-to-chassis stacking applications. Electronics assembly technicians, PCB service techs, and industrial maintenance professionals install these in control panels, HVAC control boards, and similar enclosures.

This standoff is suited for metric-fastened circuit board assemblies in residential and commercial equipment including HVAC control boards, electrical enclosures, industrial automation panels, and consumer electronics chassis. The M3 x 0.5 metric thread is a standard pitch widely used in PCB mounting hardware across these applications. The hex profile allows installation with a standard hex wrench or nut driver without slippage during torquing. Minimum order quantity is 10 pieces per order.

Key Features

• Fully threaded female M3 x 0.5 thread with 10 mm thread depth for secure fastener engagement
• Brass construction provides corrosion resistance and reliable electrical grounding continuity
• Clear zinc chromate finish meets ASTM B633 Type 1 and QQ-B-626 Comp 22 standards
• 6 mm hex body width across flats allows wrench or nut driver installation
• 10 mm overall length with 4 mm body length suits compact PCB stacking configurations
• Length tolerance of -0.13 to 0.13 mm ensures consistent board spacing across assemblies

Compatibility

Designed for use as a metric circuit board standoff in any PCB mounting application requiring an M3 x 0.5 female threaded hex standoff.

Installation Notes

De-energize all equipment and discharge any capacitors before installing or removing circuit board standoffs. Use a properly sized hex wrench or nut driver matched to the 6 mm across-flats dimension to avoid rounding the hex body. Do not over-torque; brass hardware is susceptible to thread stripping if excessive force is applied. Follow applicable assembly documentation and any relevant IPC standards for PCB mounting hardware installation.
