Electro Hardware P577M09F16-832 Hex Standoff 8-32

Product Description

The ELECTRO HARDWARE P577M09F16-832 is a female hex circuit board standoff designed to create fixed spacing between PCBs and mounting surfaces in electronic enclosures and control panels. It features 8-32 female threading, a 1.25-inch overall length, and a hex body measuring 0.25 inches across flats. Manufactured from 18-8 and Grade 303 stainless steel with an anodized bright finish, it meets the QQ-S-763 federal specification for corrosion resistance and dimensional consistency. This standoff suits HVAC control boards, electrical panel assemblies, and similar low-voltage circuit board mounting applications where reliable mechanical spacing is required.

This standoff is used in residential and light commercial applications wherever circuit boards must be secured at a fixed standoff height within an enclosure. Typical installations include HVAC control board assemblies, variable frequency drive enclosures, and industrial electrical panels. Electricians and electronics technicians use these fasteners when building or servicing control panel assemblies that require precise, secure PCB mounting. The 8-32 thread size is a common standard in North American control board hardware, making this a widely applicable standoff for panel assembly work.

Key Features

• Female 8-32 thread accepts standard 8-32 machine screws for secure PCB attachment
• 1.25-inch overall length (plus or minus 0.005 inches tolerance) provides consistent board spacing
• Hex body shape (0.25 inches across flats) allows torque application with standard hex wrenches or nut drivers
• 18-8 and Grade 303 stainless steel construction resists corrosion in humid or harsh enclosure environments
• Anodized bright finish meets QQ-S-763 federal fastener specification

Compatibility

Designed as an OEM-style replacement or new-installation hex standoff for any application requiring an 8-32 female threaded hex spacer with a 1.25-inch overall length and 0.25-inch hex body width.

Installation Notes

Installation is typically performed by licensed electricians or electronics technicians during control panel assembly or board replacement. De-energize the equipment completely before handling circuit boards or replacing standoffs. Use an appropriately sized nut driver or hex wrench sized to 0.25 inches across flats to avoid rounding the hex body. Follow applicable NEC guidelines when working inside electrical enclosures.
