Electro Hardware P341M09F16440 Hex Standoff 4-40 1in Ss

Product Description

The ELECTRO HARDWARE P341M09F16440 is a female hex circuit board standoff designed to space and support PCBs within electronic enclosures, control panels, and electrical assemblies. Machined from 303 stainless steel with a plain, bright uncoated finish, this standoff meets the QQ-S-763 fastener standard. It measures 1 inch overall length with a 3/16 inch hex body width across flats and accepts 4-40 threaded fasteners. The fully threaded female interior provides a 1/4 inch thread depth on the receiving end. Licensed electricians, electronics technicians, and panel builders typically install these fasteners during PCB mounting and chassis assembly work.

This standoff is used wherever a 4-40 female hex spacer is required to elevate or isolate a circuit board from a mounting surface. Common applications include residential and commercial control panels, HVAC control boards, electrical enclosures, and industrial PCB assemblies. The stainless steel construction makes it suitable for environments where corrosion resistance is a priority. Its inch-system sizing and standard 4-40 thread make it compatible with a wide range of PCB mounting hardware commonly found in trade and OEM applications.

Compatibility

Designed as a standard 4-40 female hex circuit board standoff for use in PCB mounting, control panel assembly, and electronic enclosure applications requiring inch-system fasteners.

Installation Notes

Installation is typically performed by electronics technicians, panel builders, or licensed electricians during PCB mounting or control panel assembly. Power down and de-energize all circuits before installing or removing standoffs in live panels. Use an appropriately sized hex driver or wrench on the 3/16 inch flats to avoid deforming the body. Do not overtighten mating screws into the female threads, as this can strip the 4-40 thread engagement in the 1/4 inch depth.
