Electro Hardware S1087-M04-F16-H Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1087-M04-F16-H is a round, female unthreaded circuit board spacer machined from aluminum alloy grade T-3 and left uncoated. It measures 0.625 inches overall length with a 0.375 inch outside diameter and a 0.171 inch inside diameter sized to accept a No. 8 screw. This spacer is used to create a fixed standoff gap between a printed circuit board and a mounting surface, providing electrical isolation and mechanical clearance. It conforms to fastener standard QQ-A-225A Comp 2. Electricians, electronics technicians, and HVAC control board installers commonly use spacers of this type during panel assembly and board replacement work.

This spacer is suited for residential and light commercial applications wherever a circuit board requires precise standoff spacing from a chassis or enclosure. Typical installation scenarios include control board mounting in HVAC air handlers, furnace control panels, and electrical enclosures. The No. 8 screw sizing fits widely used mounting hardware in standard control board assemblies. Its aluminum construction keeps weight low while offering adequate rigidity for vibration-prone equipment installations.

Key Features

• Female unthreaded design accepts No. 8 screws for straightforward board mounting
• 0.625 inch overall length provides consistent standoff height between board and mounting surface
• 0.375 inch outside diameter and 0.171 inch inside diameter machined to close tolerances
• Aluminum grade T-3 construction per QQ-A-225A Comp 2 fastener standard
• Uncoated finish - no added coating to interfere with grounding contact or dimensional fit
• Round body shape ensures uniform surface contact around the mounting hole

Compatibility

Designed as an OEM-style replacement or new-installation spacer for circuit board mounting applications using No. 8 screw hardware in standard inch-measurement assemblies.

Installation Notes

Installation is performed by qualified electricians or electronics technicians. Always de-energize and lock out the equipment before working on any control board or panel assembly. Ensure the spacer is seated flush against both the board and the mounting surface before fastening to avoid board flex or stress cracking. Follow applicable NEC guidelines for control panel assembly and grounding when installing circuit boards in HVAC or electrical enclosures.
