Electro Hardware S825-M07-F16-I Round Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S825-M07-F16-I is a round, female unthreaded circuit board spacer designed to maintain precise standoff clearance between PCBs and mounting surfaces. Machined from 18-8 303 stainless steel with an uncoated finish, it meets the QQ-S-763 fastener standard. The spacer measures 0.75 inches overall length with an outside diameter of 0.3125 inches and an inside diameter of 0.194 inches. It accepts a 10 screw size. Electricians, control board technicians, and electronics assembly professionals use this spacer wherever corrosion resistance and dimensional accuracy are required in panel and circuit board mounting applications.

This spacer is suited for residential and light commercial control panel assemblies, HVAC circuit board mounting, and industrial electronics installations where a 10 screw fastener is used. The stainless steel construction makes it appropriate for environments with elevated moisture exposure or where galvanic compatibility with stainless hardware is required. It installs in standard PCB mounting configurations that require a female unthreaded standoff at the 5/16 inch OD dimension class.

Key Features

• 18-8 303 stainless steel construction for corrosion resistance in demanding environments
• Female unthreaded bore sized at 0.194 inches ID to accept a 10 screw
• Overall length of 0.75 inches with a tight length tolerance of -0.005 to 0.005 inches
• Outside diameter of 0.3125 inches with inside diameter tolerance of 0.000 to 0.010 inches
• Uncoated finish per QQ-S-763 fastener standard
• Round body shape for consistent contact with PCB mounting pads

Compatibility

Designed as an OEM-style replacement or new-installation standoff for circuit board assemblies requiring a 10 screw size, female unthreaded, round spacer with a 0.3125 inch outside diameter and 0.75 inch overall length.

Installation Notes

Installation is performed by electricians or electronics technicians during control board assembly or replacement. Power down the equipment and discharge any capacitors before working on circuit board assemblies. Use appropriately sized 10 screws and avoid overtightening, which can crack PCB mounting pads or distort the spacer bore. Follow applicable NEC guidelines for panel and control board work.
