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

Product Description

The ELECTRO HARDWARE S1087-M04-F16-I is a round, female unthreaded aluminum circuit board spacer designed to maintain fixed standoff distance between a PCB and a mounting surface or stacking board. It accepts a No. 10 screw, measures 0.625 inches overall length, 0.375 inches outside diameter, and 0.194 inches inside diameter. Machined from Aluminum Grade T-3 per fastener standard QQ-A-225A Comp 2, this spacer ships uncoated. Electronics assemblers, PCB technicians, and industrial maintenance electricians use this type of hardware during board mounting, chassis assembly, and control panel builds.

This spacer suits applications where a No. 10 fastener passes through a circuit board to establish a secure, vibration-resistant standoff. Typical use cases include mounting control boards inside HVAC equipment, industrial enclosures, and electronic assemblies where precise board-to-surface spacing is required. The uncoated aluminum construction keeps weight low and provides adequate corrosion resistance in standard indoor environments. The round body profile and female unthreaded bore allow a screw to pass freely through without thread engagement on the spacer itself.

Key Features

• Female unthreaded bore accepts a No. 10 screw for pass-through fastening
• Overall length of 0.625 inches maintains consistent board standoff height
• Outside diameter of 0.375 inches with inside diameter of 0.194 inches
• Machined from Aluminum Grade T-3 per QQ-A-225A Comp 2 specification
• Uncoated finish - suitable for standard indoor electronic assembly environments
• Round body profile for uniform load distribution at mounting point

Compatibility

Designed as an OEM-style mounting spacer for circuit board assemblies requiring a No. 10 screw pass-through standoff with a 0.625-inch overall length and 0.375-inch outside diameter round body.

Installation Notes

PCB assemblers and electronics technicians should de-energize all equipment fully before installing or replacing board spacers. Use appropriately sized drivers and avoid over-torquing the mating fastener, as aluminum spacers can deform under excessive clamping force. Ensure the inside diameter clearance is verified against the actual screw shank diameter before assembly. Installation should follow applicable assembly drawings and any relevant IPC standards for electronic hardware mounting.
