Electro Hardware S1095-M04-F16-I Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1095-M04-F16-I is a round, female unthreaded aluminum circuit board spacer designed to maintain precise board-to-board or board-to-chassis clearance in electronic assemblies. It measures 0.75 inches in overall length with an outside diameter of 0.375 inches and an inside diameter of 0.194 inches, sized for a 10 screw. Machined from aluminum grade T-3 to fastener standard QQ-A-225A Comp 2, this spacer ships uncoated and provides a lightweight, non-threaded standoff solution. It is installed by electronics assembly technicians and field service professionals in control board applications across HVAC, electrical, and industrial equipment.

This spacer is suited for use in printed circuit board assemblies where a fixed, unthreaded standoff is required to separate boards from mounting surfaces or from one another. Its compact 0.375-inch outside diameter and 0.75-inch length make it appropriate for densely packed control enclosures and equipment panels. The female unthreaded bore accepts a 10 screw passed through from the mating component. Typical applications include PCB mounting in residential and commercial HVAC control boards, electrical panel components, and general electronic equipment assemblies.

Key Features

• Female unthreaded bore accepts a 10 screw for pass-through fastening
• 0.75-inch overall length with a tight length tolerance of -0.005 to 0.005 inches
• 0.194-inch inside diameter with an inside diameter tolerance of 0.000 to 0.010 inches
• 0.375-inch outside diameter, round body profile
• Aluminum grade T-3, uncoated finish, compliant with QQ-A-225A Comp 2
• Lightweight construction suitable for space-constrained PCB assemblies

Compatibility

Designed as an OEM-style round circuit board spacer for use with 10 screw fasteners in standard PCB standoff applications across electronic and electromechanical assemblies.

Installation Notes

Installation is typically performed by electronics technicians or qualified service personnel during PCB assembly or control board replacement. Power down and de-energize all circuits before handling circuit board components. Use care not to overtighten the mating screw through the unthreaded bore, as this spacer is not internally threaded and relies on the fastener for clamping force. Follow applicable equipment manufacturer assembly guidelines and relevant electrical codes when servicing control board enclosures.
