Electro Hardware P521M09F16-832 Hex Board Standoff 8-32

Product Description

The ELECTRO HARDWARE P521M09F16-832 is a female hex circuit board standoff designed to create a fixed, threaded separation between a PCB and a mounting surface or between stacked boards. Machined from 18-8 and Grade 303 stainless steel with an anodized bright finish, this standoff accepts an 8-32 thread and measures 0.375 inches overall length with a hex body width across flats of 0.25 inches. The hex profile allows installation and removal with standard hex drivers or wrenches. Electronics assembly technicians and field service pros working with control boards in HVAC, electrical, or industrial enclosures will encounter this hardware on a regular basis.

This standoff is suited for circuit board mounting applications where corrosion resistance and dimensional consistency are required. The stainless steel construction makes it appropriate for environments with moisture exposure or where longevity of the fastener is a factor. It is commonly used during PCB assembly, control board replacement, and panel fabrication in residential and commercial equipment. The 8-32 thread size is a widely used standard pitch in electronics and control board hardware, making this standoff compatible with many existing threaded holes in metal enclosures and PCB mounting pads.

Key Features

• Female 8-32 threaded hex standoff for PCB-to-surface or board-to-board mounting
• 18-8 and Grade 303 stainless steel construction for corrosion resistance
• Anodized bright finish for surface protection
• Hex body profile for installation with standard drivers or wrenches
• Meets QQ-S-763 fastener standard
• Length tolerance of -0.005 to 0.005 inches for precise stack height control

Compatibility

Designed as an OEM-style replacement or standard-use hex standoff for circuit board mounting applications requiring an 8-32 female thread and 0.375 inch overall length in inch-measurement systems.

Installation Notes

Installation is typically performed by electronics assembly technicians or field service professionals. Power down and de-energize the equipment fully before handling or replacing any circuit board hardware. Use an appropriately sized hex driver or nut driver matching the 0.25 inch width across flats to avoid rounding the hex body. Avoid over-torquing, as stainless steel fasteners in threaded PCB standoff holes can gall or damage the board mounting pad.
