Electro Hardware 1483M12F21-1032 Hex Standoff 10-32

Product Description

The ELECTRO HARDWARE 1483M12F21-1032 is a male-female hex circuit board standoff designed to create precise spacing between PCBs or between a board and a chassis in electronic assemblies. Machined from Grade 2 steel with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-S-633 standards, this standoff delivers corrosion resistance suitable for panel and enclosure environments. The 10-32 thread size, 2-3/8 inch overall length, and 1/4 inch hex width across flats make it a direct-fit hardware fastener for controlled-distance board mounting in HVAC control panels, electrical enclosures, and similar trade applications.

This standoff is used wherever a circuit board must be mounted with a fixed, measured gap from a substrate or stacked against a second board. Common install scenarios include HVAC control board assemblies, electrical panel sub-assemblies, and industrial enclosures requiring rigid, non-shorting board support. The male end threads into the mating board or standoff while the female end accepts the next fastener or board in the stack, allowing clean multi-board or board-to-chassis configurations.

Key Features

• Male-female hex configuration allows stackable board mounting in a single fastener
• 10-32 thread size with 3/8 inch thread length on the male end and 1/2 inch thread depth on the female end
• 2-3/8 inch overall length with a 2 inch hex body for consistent board standoff height
• Grade 2 steel construction with zinc-plated finish per ASTM B633 Type 1 and QQ-S-633
• 1/4 inch width across flats allows standard hex tooling for installation and removal
• Length tolerance of -0.005 to +0.005 inches for precise fit in tight board assemblies

Compatibility

Designed as an OEM-style replacement or service fastener for circuit board mounting applications requiring a 10-32 male-female hex standoff with a 2-3/8 inch overall length.

Installation Notes

Installation is typically performed by electricians or electronics technicians during control board service or panel assembly. Power down and de-energize the equipment fully before handling any circuit board or standoff hardware. Use an appropriately sized hex driver or wrench sized for 1/4 inch across flats to avoid rounding the hex body. Follow applicable NEC requirements for enclosure and control panel assembly when replacing standoff hardware in field installations.
