Electro Hardware 1325M06F16440 Hex Standoff 4-40 7/8 in

Product Description

The ELECTRO HARDWARE 1325M06F16440 is a male-female hex circuit board standoff used to create fixed spacing between stacked PCBs or between a circuit board and a chassis. The body is machined from aluminum to T3 material grade and meets the QQ-A-225A Comp 2 fastener standard. It features a 4-40 thread size, an overall body length of 0.875 inches, and a hex width across flats of 0.1875 inches. The bright, uncoated finish keeps the aluminum surface bare. Electronics assembly technicians and field service technicians install these standoffs during board mounting and enclosure integration work.

This standoff is suited for use in control boards, electronic enclosures, and PCB assemblies requiring precise vertical separation. The male thread on one end inserts into a mating female receiver, while the female threaded end accepts the next fastener or standoff in the stack. Common applications include HVAC control board mounting, industrial panel assembly, and general electronics enclosure work where a compact, lightweight aluminum spacer is required.

Key Features

• Male-female hex configuration allows stacking of multiple standoffs or direct fastener engagement
• 4-40 unified thread on both ends for broad PCB hardware compatibility
• Overall body length of 0.875 inches with a tight length tolerance of -0.005 to +0.005 inches
• 3/16 inch (0.1875 inches) hex width across flats for standard hex driver installation
• Aluminum construction with T3 material grade keeps weight low
• Meets QQ-A-225A Comp 2 fastener standard

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit board mounting applications using 4-40 threaded hardware in inch-measurement assemblies.

Installation Notes

Installation is performed by electronics assembly technicians or qualified service technicians. Always de-energize the equipment and discharge any capacitors before working inside an enclosure. Use a hex driver or nut driver sized for 3/16 inch flats to seat the standoff without overtightening, as aluminum threads can strip under excess torque. Verify mating thread engagement depth matches the 1/4 inch thread depth specification before finalizing the assembly.
