Electro Hardware 1431M12F21-632 Hex Standoff 6-32 5/8 in

Product Description

The ELECTRO HARDWARE 1431M12F21-632 is a male-female hex circuit board standoff designed to space and support printed circuit boards within enclosures, control panels, and electronic assemblies. It features a 6-32 thread size, an overall length of 0.625 inches, and a hex body shape that allows tightening with a standard wrench or nut driver. The standoff is machined from Grade 2 steel with a zinc-plated finish that meets ASTM B633 Type 1 and QQ-S-633 standards. The male end threads into the mounting surface while the female end accepts the next standoff or fastener, making it suitable for stacking PCB layers or securing boards at a fixed height.

This standoff is used in residential and commercial control board assemblies, HVAC control panel repairs, and general electronic equipment servicing. It is appropriate wherever a fixed board-to-surface or board-to-board spacing of 0.625 inches is required. The 0.25-inch width across flats allows installation in tight board layouts. Licensed electricians, HVAC technicians, and electronics technicians commonly use this hardware when assembling or replacing control boards in equipment enclosures.

Key Features

• Male-female hex configuration for stacking or single-layer PCB mounting
• 6-32 thread size with 0.25-inch width across flats for compact board layouts
• Overall length of 0.625 inches with a body length of 0.375 inches and thread length of 0.25 inches
• Grade 2 steel construction with zinc-plated finish for corrosion resistance
• Meets ASTM B633 Type 1 and QQ-S-633 standards
• Length tolerance of -0.005 to 0.005 inches for consistent board spacing

Compatibility

Designed as an OEM-style replacement or service hardware for circuit board assemblies requiring 6-32 threaded male-female hex standoffs with a 0.625-inch overall length.

Installation Notes

Power down and de-energize all equipment before servicing circuit boards or replacing standoffs. A nut driver or small open-end wrench sized for a 0.25-inch hex body is recommended for installation. Hand-tighten first to avoid cross-threading, then snug with the tool. Follow applicable NEC guidelines and manufacturer torque recommendations when reassembling control enclosures.
