Electro Hardware 1451M12F21-1032 Hex Standoff 10-32

Product Description

The ELECTRO HARDWARE 1451M12F21-1032 is a male-female hex circuit board standoff designed to space and secure printed circuit boards within electronic enclosures and control panels. Machined from steel with a zinc-plated finish meeting ASTM B633 Type 1 and QQ-S-633 standards, this standoff provides reliable electrical isolation and mechanical separation between boards or between a board and a mounting surface. It measures 1.375 inches in overall length with a 1-inch hex body and a 0.25-inch width across flats. The 10-32 male thread on one end and 10-32 female thread on the other end allow stacking and secure fastening in standard PCB mounting patterns.

This standoff is used in residential and commercial control panel assemblies, HVAC circuit board mounting applications, and general electronic enclosure builds where precise board-to-board or board-to-chassis spacing is required. Electricians, controls technicians, and electronics assemblers install this type of hardware when building or servicing control boards that require rigid, repeatable standoff heights. The hex body allows wrench engagement for consistent torque application across multiple fastening points.

Key Features

• Male 10-32 external thread on one end, female 10-32 internal thread on the other end for stacking capability
• 1.375 inches overall length with 1-inch hex body length
• 0.25-inch width across flats for standard hex tool engagement
• Steel construction with zinc plating to ASTM B633 Type 1 and QQ-S-633 standards
• Length tolerance of -0.005 to 0.005 inches for consistent board spacing
• 3/8-inch thread length on male end, 1/2-inch thread depth on female end

Compatibility

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

Installation Notes

Installation is performed by electronics assemblers, electricians, or controls technicians working on circuit board mounting and enclosure builds. De-energize all equipment and discharge any stored energy before working inside control panels or enclosures. Use an appropriately sized hex wrench or nut driver on the 0.25-inch flats to seat the standoff without over-tightening, which can crack PCB mounting holes. Follow applicable NEC requirements when installing standoffs within listed electrical enclosures.
