Electro Hardware P529M12F21-832 Female Hex Standoff 8-32

Product Description

The ELECTRO HARDWARE P529M12F21-832 is a female hex circuit board standoff designed to mount and space printed circuit boards within enclosures, control panels, and electronic assemblies. Machined from Grade 2 steel with a zinc-plated clear chromate finish, this standoff meets ASTM B633 Type 1 and QQ-S-633 finish standards. The internal thread accepts an 8-32 fastener, and the hex body measures 0.25 inches across flats for easy wrench engagement. Overall length is 0.5 inches. It is sized for close-clearance board mounting where a compact standoff is required.

This standoff is suited for use in residential and commercial control board assemblies, HVAC equipment panels, electrical enclosures, and light industrial electronics. Electricians, controls technicians, and electronics assembly professionals install these standoffs when securing circuit boards to chassis or sub-panels. The hex body profile allows installation and removal with standard hex drivers or nut drivers without slipping on the fastener flats.

Key Features

• Female 8-32 internal thread accepts standard machine screws for board attachment
• Hex body shape with 0.25-inch width across flats for wrench or nut driver engagement
• 0.5-inch overall length provides consistent board-to-chassis clearance
• Grade 2 steel construction for reliable mechanical strength in panel applications
• Zinc-plated clear chromate finish per ASTM B633 Type 1 and QQ-S-633 for corrosion resistance
• Length tolerance of -0.005 to 0.005 inches for consistent stacking height

Compatibility

Designed as a standard 8-32 female hex circuit board standoff for use in electronic assemblies, control panels, and enclosures requiring inch-system fasteners and a 0.5-inch board standoff height.

Installation Notes

Installation is typically performed by electricians or controls technicians during panel assembly or circuit board replacement. Power down and de-energize the enclosure before installing or removing standoffs near live circuit boards. Use a properly sized nut driver or hex wrench matched to the 0.25-inch flats to avoid rounding the hex body. Follow applicable NEC guidelines for enclosure assembly and board mounting practices.
