Electro Hardware ESO-832-12ZI Hex Standoff 8-32 3/8in 25-pack

Product Description

The ELECTRO HARDWARE ESO-832-12ZI is a female hex circuit board standoff designed to create precise vertical spacing between PCBs and mounting surfaces in electronic assemblies. Manufactured from steel with a zinc-plated finish, this standoff features an 8-32 thread size, an overall length of 0.375 inches, and a hex body width across flats of 0.312 inches. It uses a self-clinching with through-hole fastening method, allowing secure, vibration-resistant mounting in panel and chassis applications. Licensed electricians, electronics assembly technicians, and field service professionals install these fasteners during control board replacement and panel builds.

This standoff is well suited for residential and commercial electronic control assemblies, including HVAC control boards, industrial automation panels, and general PCB mounting applications. The hex body profile allows standard hex drivers or nut drivers to apply consistent torque during installation. Sold in a package quantity of 25 units, it is appropriate for service shops, production runs, or field technicians who need a ready supply of matching standoffs for multi-board assemblies.

Key Features

• Female 8-32 thread accepts standard machine screws for secure PCB-to-standoff fastening
• Hex body shape allows positive grip with a nut driver or open-end wrench
• Zinc-plated steel construction provides corrosion resistance in typical indoor panel environments
• Self-clinching with through-hole fastening method for reliable, tool-installed mounting
• Overall length of 0.375 inches provides consistent board-to-surface standoff clearance
• Package of 25 supports multi-board assemblies and stock replenishment

Compatibility

Designed as an OEM-style replacement or maintenance supply standoff for circuit board assemblies requiring an 8-32 female hex standoff with a 0.375-inch overall length in inch-standard fastener systems.

Installation Notes

Installation is typically performed by licensed electricians or electronics assembly technicians. De-energize all circuits and discharge any stored capacitance before removing or installing control boards. A hex driver or open-end wrench sized to the 0.312-inch width across flats should be used to seat the standoff without stripping the hex body. Follow NEC guidelines and equipment manufacturer documentation when reinstalling control boards in electrical enclosures.
