Electro Hardware S1111-M07-F16-G Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1111-M07-F16-G is a round, female unthreaded circuit board spacer designed to create precise standoff clearance between a printed circuit board and its mounting surface. Built from 18-8 Grade 303 stainless steel in an uncoated finish, this spacer meets the QQ-S-763 fastener standard. It accepts a Number 6 screw and measures 1 inch in overall length, with an inside diameter of 0.141 inches and an outside diameter of 0.375 inches. Electricians, electronics technicians, and control board installers use this type of hardware when mounting sensitive circuit assemblies in HVAC controls, electrical panels, and similar enclosures.

This spacer is suited for applications requiring a corrosion-resistant standoff in both residential and light commercial electrical or HVAC control assemblies. Its stainless steel construction makes it appropriate for environments where mild moisture exposure or long service life is a concern. The female unthreaded body allows a Number 6 fastener to pass through cleanly, maintaining consistent board-to-surface spacing across multiple mounting points. It ships individually and is also available in small quantities for service and repair work.

Key Features

• Round body with female unthreaded design accepts Number 6 screws
• 18-8 Grade 303 stainless steel construction for corrosion resistance
• Meets QQ-S-763 fastener standard
• Uncoated finish — no risk of coating interference at contact points
• Tight length tolerance of -0.005 to 0.005 inches for consistent standoff height
• Inside diameter tolerance of 0.000 to 0.010 inches for reliable fastener fit

Compatibility

Designed as an OEM-style replacement or new-installation standoff spacer for circuit board mounting applications requiring a Number 6 screw, 1-inch overall length, and a 0.375-inch outside diameter round body.

Installation Notes

Installation should be performed by a qualified electrician or electronics technician. De-energize all circuits and verify zero voltage before handling any circuit board assembly. Use a calibrated torque driver appropriate for Number 6 fasteners to avoid over-tightening, which can crack board substrates. Confirm spacer seating is flush and consistent across all mounting points before restoring power.
