Electro Hardware 1443M12F21-1032 Hex Standoff 10-32

Product Description

The ELECTRO HARDWARE 1443M12F21-1032 is a male-female hex circuit board standoff designed to create precise spacing between PCBs, chassis panels, and mounting surfaces in electronic assemblies. The standoff features a 10-32 threaded male end and a 10-32 threaded female end, allowing boards to be stacked or secured at a fixed distance. The hex body measures 0.25 inches across flats, giving technicians a clean grip surface for installation with a standard wrench or socket. Overall length is 1.125 inches, with a body length of 0.75 inches and a thread depth of 0.5 inches. Fabricated from Grade 2 steel with a zinc-plated finish, it meets ASTM B633 Type 1 and QQ-S-633 standards for corrosion resistance and mechanical durability.

This standoff is used in residential and commercial electronic enclosures, control panels, HVAC control boards, and industrial PCB assemblies wherever a fixed, rigid spacer between board layers or mounting surfaces is required. It suits applications calling for a standard inch-series 10-32 fastener pattern. Electricians, electronics technicians, and HVAC controls installers commonly use this type of hardware when mounting or replacing control boards inside equipment enclosures.

Key Features

• Male-female hex configuration allows board stacking with a single fastener pass-through
• 10-32 thread size on both ends for compatibility with standard inch-series hardware
• Overall length of 1.125 inches with 0.75-inch hex body length for consistent PCB standoff spacing
• Grade 2 steel construction with zinc-plated finish meets ASTM B633 Type 1 and QQ-S-633 standards
• 0.25-inch hex width across flats allows installation with a standard wrench or nutdriver
• Length tolerance of -0.005 to 0.005 inches for precise board-to-board spacing

Compatibility

Designed as a standard inch-series male-female hex standoff for circuit board mounting applications using 10-32 threaded hardware in electronic enclosures and control panel assemblies.

Installation Notes

Installation is performed by electronics technicians or electricians working on control board assemblies. De-energize the equipment fully and discharge any capacitors before handling PCBs or mounting hardware. Use an appropriately sized wrench or nutdriver on the hex body to avoid rounding the flats. Do not overtighten, as excess torque can crack PCB mounting pads or distort the standoff threads.
