Electro Hardware MMF1341M06F16M3 Hex Standoff M3x0.5

Product Description

The ELECTRO HARDWARE MMF1341M06F16M3 is a male-female hex circuit board standoff designed to create fixed spacing between PCB layers or between a board and a mounting surface. Machined from aluminum alloy T3 stock to QQ-A-225A Comp 2 specification, it features a hexagonal body for wrench engagement and delivers reliable, repeatable standoff height in precision electronic assemblies. The overall length is 29.76 mm, the body length is 25.00 mm, and the width across the hex flats is 4.50 mm. The M3 x 0.5 thread on both ends accommodates standard metric hardware. Electronics assembly technicians and PCB integration specialists are the primary installers of this fastener.

This standoff is used in residential and commercial electronic control assemblies where circuit boards must be mounted with controlled clearance. Typical applications include HVAC control board assemblies, industrial electronics enclosures, and custom PCB stacking configurations. The male end threads into the board or chassis while the female end accepts a mating screw from the next layer, enabling clean stacked-board installations. The bright, uncoated aluminum finish is suited for indoor, low-corrosion environments where weight and conductivity are considerations.

Key Features

• M3 x 0.5 male-female thread configuration for stacked PCB or board-to-chassis mounting
• Hexagonal body profile allows wrench-driven installation and removal
• Overall length of 29.76 mm with a body length of 25.00 mm for consistent board spacing
• Aluminum T3 material meets QQ-A-225A Comp 2 specification for dimensional accuracy
• Bright, uncoated finish - no added coating thickness to affect fitment
• Length tolerance of -0.150 to 0.150 mm for repeatable stack-up control

Compatibility

Designed as an OEM-style metric standoff for PCB and electronic enclosure assemblies requiring M3 x 0.5 threaded hardware with a 4.50 mm hex body width.

Installation Notes

Installation is typically performed by electronics assembly technicians or field service technicians working on control board assemblies. De-energize all equipment fully before servicing any circuit board or its mounting hardware. Use a properly sized metric hex driver or wrench sized to the 4.50 mm flats to avoid rounding the body. Do not overtighten - aluminum threads are susceptible to galling and stripping if torqued beyond hand-tight plus minimal wrench engagement without lubrication.
