Electro Hardware MP411M09F16M2.5 Hex Board Standoff M2.5

Product Description

The ELECTRO HARDWARE MP411M09F16M2.5 is a female hex circuit board standoff designed to create fixed spacing between a PCB and a mounting surface or a second board. Machined from 303 stainless steel with a plain, bright, uncoated finish, this standoff uses a fully threaded M2.5 x 0.45 female thread with a 6 mm thread depth. The hexagonal body measures 4.5 mm across flats, making it compatible with standard hex drivers. With a 6 mm overall length, it suits compact PCB assemblies where precise, repeatable standoff height is required. Licensed electricians, electronics technicians, and OEM assembly technicians typically install this hardware during board mounting operations.

This standoff is suited for metric PCB mounting applications in residential and commercial electronic control assemblies, including HVAC control boards, electrical enclosures, and industrial equipment panels. The M2.5 x 0.45 thread size is common in compact control modules and low-voltage circuit board assemblies. The stainless steel construction provides corrosion resistance in environments where moisture or humidity may be a concern. The plain finish keeps the mating thread engagement clean and predictable without added coating thickness affecting fit.

Key Features

• Female M2.5 x 0.45 thread, fully threaded with 6 mm thread depth
• 303 stainless steel construction meets QQ-S-763 fastener standard
• Hexagonal body at 4.5 mm across flats allows wrench or hex driver installation
• 6 mm overall length with length tolerance of -0.13 to 0.13 mm for consistent board spacing
• Plain, uncoated bright finish — no coating buildup affecting thread fit
• Metric system measurement; UNSPSC Code 31161816

Compatibility

Designed for use in metric PCB mounting applications requiring M2.5 x 0.45 female threaded standoffs with a 6 mm hex body profile.

Installation Notes

Install using a hex driver or small wrench sized to the 4.5 mm across-flats dimension. De-energize and discharge any circuit board assembly fully before installing or removing standoffs. Avoid over-torquing the small M2.5 thread, as stainless-to-stainless fasteners can gall if driven without care. Follow applicable IPC assembly standards and equipment manufacturer documentation for board mounting procedures.
