Electro Hardware S341M07F16E Round Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S341M07F16E is a round, female unthreaded circuit board spacer designed to create consistent standoff clearance between a PCB and a mounting surface. Manufactured from Grade 303 stainless steel and left uncoated with a bright finish, this spacer meets the QQ-S-763 fastener standard. It measures 1 inch overall length with a 0.116 inch inside diameter and a 3/16 inch (0.1875 inch) outside diameter. The inside diameter tolerance runs 0.000 to 0.010 inch and the length tolerance is -0.005 to 0.005 inch. Sized for a 4 screw, it is suited for precision electronic assembly and control board mounting tasks performed by electronics technicians, HVAC service pros, and electrical panel assemblers.

This spacer is a standard inch-system component used wherever a 4 screw mounting pattern is required for circuit board standoff applications. Typical use cases include mounting control boards in HVAC equipment, electrical enclosures, and industrial panels where a stainless steel fastener is preferred for corrosion resistance and dimensional consistency. Its small outside diameter and compact 1 inch length make it appropriate for tight board layouts where clearance between the PCB and chassis must be maintained precisely and reliably.

Key Features

• Grade 303 stainless steel construction meets QQ-S-763 fastener standard for dimensional and material consistency
• Female unthreaded bore accepts a 4 screw for straightforward PCB standoff installation
• 1 inch overall length with tight length tolerance of -0.005 to 0.005 inch
• 0.116 inch inside diameter with tolerance of 0.000 to 0.010 inch for reliable fastener fit
• 3/16 inch (0.1875 inch) outside diameter in a round body profile for compact board layouts
• Bright uncoated finish maintains bare stainless appearance and avoids coating interference in precision assemblies

Compatibility

Designed as an OEM-style replacement or direct-fit standoff spacer for circuit board assemblies requiring a 4 screw, female unthreaded, round stainless steel spacer in the inch measurement system.

Installation Notes

Installation is performed by electronics technicians or qualified HVAC and electrical service professionals. Power down and de-energize any equipment before handling or replacing control board hardware. Use appropriately sized 4 fasteners and a standard screwdriver or nut driver; avoid over-torquing into the unthreaded bore. Follow applicable NEC or equipment manufacturer guidelines when working inside electrical enclosures.
