Electro Hardware P577M09F16-632 Hex Standoff 6-32

Product Description

The ELECTRO HARDWARE P577M09F16-632 is a female hex circuit board standoff designed to create precise spacing between PCBs and enclosure panels or stacked boards in electronic assemblies. The standoff features a 6-32 female thread, an overall length of 1.25 inches, and a hex body width across flats of 0.25 inches. Manufactured from 18-8 and Grade 303 stainless steel with an anodized bright finish, it delivers corrosion resistance suitable for both indoor and industrial enclosure environments. Electricians and control panel technicians reach for this style of fastener when building or servicing motor control centers, HVAC control boards, and similar electrical assemblies.

This standoff is used in commercial and industrial applications where printed circuit boards must be securely mounted with controlled standoff height. Typical install scenarios include control panel builds, PCB stack assemblies, and service replacement of damaged or corroded mounting hardware in HVAC units, variable frequency drives, and other enclosure-based electronics. The inch-system thread sizing and standard hex profile make it compatible with common installation tooling across trade environments.

Key Features

• Female 6-32 thread accepts standard machine screws for secure PCB mounting
• 1.25 inches overall length provides consistent board-to-board or board-to-panel spacing
• Hex body at 0.25 inches width across flats allows wrench or socket installation and removal
• 18-8 and Grade 303 stainless steel construction resists corrosion in enclosure environments
• Anodized bright finish meets QQ-S-763 fastener standard
• Length tolerance of -0.005 to 0.005 inches ensures consistent stack height across multi-board assemblies

Compatibility

Designed as an OEM-style replacement or new-installation standoff for printed circuit board assemblies using inch-system 6-32 threaded hardware in standard hex standoff configurations.

Installation Notes

Installation is performed by electricians or electronics technicians during control panel assembly or PCB service. De-energize all circuits and follow LOTO procedures before working inside any electrical enclosure. Use a wrench sized to 0.25 inches across flats to seat the standoff without over-torquing, which can crack PCB mounting pads. Verify thread engagement on both the standoff and the mating fastener before applying any load to the board.
