Electro Hardware P333M09F16440 Hex Standoff 4-40 7/8in Ss

Product Description

The ELECTRO HARDWARE P333M09F16440 is a female hex circuit board standoff designed to space and support printed circuit boards within electronic assemblies. Machined from 303 stainless steel with a plain bright finish, it provides corrosion resistance and reliable thread engagement in demanding environments. The standoff features a 4-40 female thread, an overall length of 0.875 inches, and a hex body width across flats of 0.1875 inches. Thread depth measures 0.25 inches, and the hex body shape allows installation and removal with standard hex drivers or wrenches. This fastener is manufactured to QQ-S-763 standards, making it suitable for applications where material and dimensional consistency are required.

This standoff is used in PCB mounting applications across HVAC control boards, electrical enclosures, industrial control panels, and similar assemblies where boards must be elevated and secured at a fixed standoff height. The female thread accepts a mating male screw from above, allowing the board to be fastened in place. The compact 3/16-inch hex profile suits installations where board spacing is tight. It is typically installed by electronics assemblers, electrical panel builders, and service technicians performing control board replacements or enclosure builds in commercial and residential equipment.

Compatibility

Designed as an OEM-style replacement or new-installation fastener for circuit board mounting applications requiring a 4-40 female hex standoff in the 7/8-inch overall length range.

Installation Notes

Installation is typically performed by qualified electronics assemblers or electricians working on control board assemblies. Always de-energize and lock out the equipment before servicing any circuit board or control enclosure. Use a correctly sized hex driver or wrench matched to the 3/16-inch width across flats to avoid rounding the hex body. Follow applicable electrical codes and equipment manufacturer guidelines when replacing or installing circuit board hardware.
