Electro Hardware MP409M09F16M3 Hex Standoff M3x0.5

Product Description

The ELECTRO HARDWARE MP409M09F16M3 is a female hex circuit board standoff designed to create fixed spacing between printed circuit boards and mounting surfaces in electronic assemblies. Machined from 303 stainless steel with a plain bright finish, this standoff features a fully threaded female interior with an M3 x 0.5 thread size and a 5 mm thread depth. The overall length is 5 mm and the hex body measures 4.5 mm across flats. It meets QQ-S-763 stainless steel material standards. Licensed electricians, electronics technicians, and panel builders install these fasteners in control boards, instrumentation enclosures, and industrial equipment assemblies.

This standoff is suited for metric-threaded circuit board mounting applications in both commercial and industrial settings. The fully threaded female hex body allows a machine screw to pass through from each end, securing PCBs at a consistent standoff height. The compact 5 mm overall length makes it appropriate for tight board-to-board or board-to-chassis spacing in control panels and electrical enclosures.

Key Features

• Female hex body with fully threaded M3 x 0.5 interior through 5 mm thread depth
• 5 mm overall length with a length tolerance of -0.13 to 0.13 mm
• 4.5 mm width across flats for standard hex driver installation
• 303 stainless steel construction meeting QQ-S-763 fastener standard
• Plain bright uncoated finish suitable for corrosion-resistant applications

Compatibility

Designed as an OEM-style metric standoff for circuit board mounting applications requiring M3 x 0.5 female threaded hex standoffs.

Installation Notes

This standoff is installed by electronics technicians and licensed electricians working on control boards or panel assemblies. De-energize the assembly completely before installing or removing circuit board hardware. A standard hex driver or nut driver sized for 4.5 mm across flats should be used to seat the standoff without over-torquing the threaded body. Minimum order quantity is 10 units.
