Electro Hardware S1067-M10-F21-I Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1067-M10-F21-I is a round, female unthreaded circuit board spacer designed for use with number 10 screws. Manufactured from Grade 2 steel with a zinc-plated finish, this spacer meets ASTM B633 and QQ-S-633 Type 1 standards. It measures 0.3125 inches overall length, with an inside diameter of 0.194 inches and an outside diameter of 0.375 inches. The zinc plating provides corrosion resistance suitable for indoor electronic and electrical panel applications. Electricians, panel builders, and electronics technicians use these spacers to maintain proper board standoff distance and secure PCB mounting in enclosures and control panels.

This spacer is suited for residential and commercial electrical panel assembly, control board installations, and industrial enclosure builds where a number 10 fastener is used. It is appropriate wherever a female unthreaded round spacer is required to maintain consistent spacing between a circuit board and a mounting surface. The compact 5/16-inch length makes it well-suited for tight assemblies with limited clearance. Inside diameter tolerance runs 0.000 to 0.010 inches and length tolerance runs -0.005 to 0.005 inches, supporting precise, repeatable board mounting.

Key Features

• Female unthreaded round body sized for number 10 screws
• Grade 2 steel construction meets ASTM B633 and QQ-S-633 Type 1 standards
• Zinc-plated finish for corrosion resistance in indoor enclosures
• Tight length tolerance of -0.005 to 0.005 inches for consistent board standoff
• Inside diameter tolerance of 0.000 to 0.010 inches for reliable fastener fit
• Compact 5/16-inch overall length for use in space-constrained assemblies

Compatibility

Designed as an OEM-style replacement or new-installation spacer for circuit board mounting applications using number 10 screw fasteners in electrical panels, control boards, and industrial enclosures.

Installation Notes

Installation is typically performed by licensed electricians or panel assembly technicians. De-energize all circuits and follow lockout/tagout procedures before servicing any control panel or circuit board assembly. Verify the fastener thread size and board clearance requirements before selecting spacer quantity and placement. Applicable work should conform to NEC guidelines for enclosure and panel assembly.
