Electro Hardware 1435M03F21-1032 Hex Standoff 10-32

Product Description

The ELECTRO HARDWARE 1435M03F21-1032 is a male-female hex circuit board standoff used to create fixed spacing between printed circuit boards and mounting surfaces or between stacked boards in an enclosure. It features a 10-32 thread size with a male thread on one end and a female threaded bore on the other, allowing boards to be fastened at a precise, consistent height. The hex body measures 0.25 inches across flats, making it wrenchable for secure installation. Constructed from brass with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-B-626 Comp 22 standards, this standoff is suited for use in control panels, HVAC control boards, and industrial electronics assemblies.

This standoff is used in applications where circuit boards must be securely mounted and isolated from a chassis or secondary board. Common installation scenarios include HVAC control board assemblies, electrical enclosures, and industrial equipment panels. The 0.875 inch overall length, 0.5 inch body length, and 0.375 inch thread length make it appropriate for standard PCB mounting configurations requiring a defined standoff height. Electricians, HVAC controls technicians, and electronics assembly professionals typically install these fasteners during equipment build or field board replacement.

Key Features

• Male-female thread configuration allows stacking or chassis-mount applications with a single fastener
• 10-32 unified fine thread on both male and female ends for secure engagement
• Hex body shape at 0.25 inches across flats allows installation with standard open-end or box wrenches
• Brass construction with zinc-plated finish for corrosion resistance in control panel environments
• Meets ASTM B633 Type 1 and QQ-B-626 Comp 22 finish and material standards
• Length tolerance of -0.005 to 0.005 inches ensures consistent board standoff height

Compatibility

Designed as a standard 10-32 male-female hex standoff for use in circuit board mounting applications requiring an 0.875 inch overall standoff height with a 0.25 inch hex body.

Installation Notes

Installation is performed by electricians or controls technicians working on panel boards or PCB assemblies. De-energize all equipment and discharge any capacitors before handling circuit boards or fasteners in live enclosures. Use an appropriately sized open-end wrench on the hex body to avoid rounding; do not overtighten, as brass threads can be damaged by excessive torque. Follow applicable NEC guidelines for enclosure work when installing or replacing control boards in electrical panels.
