Electro Hardware 1317M09F16440 Hex Standoff 4-40 Ss

Product Description

The ELECTRO HARDWARE 1317M09F16440 is a male-female hex circuit board standoff used to create fixed spacing between PCBs and mounting surfaces in electronic assemblies. Machined from 303 stainless steel with a passivated finish, it meets QQ-S-763 standards for corrosion resistance. The standoff features a 4-40 threaded male end on one side and a 4-40 threaded female end on the other, allowing boards to be stacked or elevated at a consistent height. Overall body length is 0.625 inches with a width across flats of 0.1875 inches. Electronics assemblers, control board technicians, and HVAC service technicians working with control assemblies use this hardware for secure, repeatable board mounting.

This standoff is suited for PCB mounting applications in HVAC control panels, electrical enclosures, and commercial or residential electronic assemblies where a 4-40 thread pattern and 5/8-inch standoff height are required. The hex body profile allows installation and removal with standard hex drivers or wrenches without slipping. The passivated stainless steel construction makes it appropriate for environments where mild corrosion resistance is needed. It is sold individually, with a minimum order quantity of 5 units.

Compatibility

Designed as a standard 4-40 hex circuit board standoff for use in PCB mounting applications requiring a 5/8-inch standoff height and a hex body style in the inch measurement system.

Installation Notes

Installation is typically performed by electronics technicians or control board service personnel. Power down all equipment and discharge any stored energy before servicing circuit boards or control assemblies. Use an appropriately sized hex driver or nut driver matching the 0.1875-inch across-flats dimension to avoid rounding the hex body. Do not overtighten — follow the torque requirements of the mating board or chassis specification, as no product-specific torque value is provided.
