Electro Hardware P537M09F16-632 Hex Standoff 6-32 5/8 in

Product Description

The ELECTRO HARDWARE P537M09F16-632 is a female hex circuit board standoff machined from 18-8 and Grade 303 stainless steel with an anodized bright finish. It accepts a 6-32 female thread and measures 0.625 inches overall length with a 0.25-inch width across flats on its hex body. Standoffs like this one are used to create a fixed, electrically isolated gap between a printed circuit board and a mounting surface, panel, or second PCB. Installation is typically performed by electronics assemblers, field service technicians, and control panel builders working in HVAC, industrial, or electrical enclosure applications where board-level hardware must be securely and repeatably positioned.

This standoff is sized for light-duty PCB mounting applications where a 6-32 thread pitch is specified. The hex body allows tightening with standard hex drivers or a wrench without marring the fastener. Its stainless steel construction makes it suitable for environments where mild corrosion resistance is needed, including control panels in HVAC equipment, electrical enclosures, and instrumentation assemblies. The anodized bright finish provides additional surface protection. Sold individually, this part suits low-quantity repair, replacement, or prototype builds.

Key Features

• Female 6-32 thread accepts machine screws for board-to-standoff fastening
• 0.625-inch overall length with tight length tolerance of -0.005 to 0.005 inches
• 0.25-inch hex width across flats for wrench or hex driver installation
• 18-8 and Grade 303 stainless steel construction for corrosion resistance
• Anodized bright finish for added surface protection
• Meets QQ-S-763 fastener standard

Compatibility

Designed as a standard 6-32 female hex circuit board standoff for use in PCB mounting applications requiring inch-series hardware with a hex body profile.

Installation Notes

Always de-energize and discharge any control board or panel before installing or removing standoffs. Use a correctly sized hex driver or open-end wrench matched to the 0.25-inch width across flats to avoid rounding the hex body. Do not overtighten, as stainless fasteners are subject to galling if driven with excessive force. Follow applicable electrical enclosure and control panel assembly standards when securing circuit boards in equipment.
