Electro Hardware MS1011M07F16D Circuit Board Spacer M3

Product Description

The ELECTRO HARDWARE MS1011M07F16D is a round, female unthreaded circuit board spacer designed for M3 screw applications in electronic assemblies. Manufactured from Grade 303 stainless steel to the QQ-S-763 fastener standard, it delivers corrosion resistance and dimensional stability in demanding environments. The spacer measures 6 mm overall length with a 6 mm outside diameter and an inside diameter ranging from 3.2 mm to 3.6 mm. The bright, uncoated finish leaves the base material exposed, making it suitable for applications where coating interference is a concern. Electronics assemblers, PCB technicians, and electrical panel builders use these spacers to maintain precise board-to-board or board-to-chassis standoff distances.

This spacer is used in residential and commercial electronic control assemblies, circuit board mounting applications, and electrical enclosures where M3 metric hardware is specified. The metric dimensioning makes it a natural fit for imported electronic equipment, HVAC control boards, and industrial control panels that follow metric fastener standards. Its round body profile and female unthreaded design allow a standard M3 screw to pass through or seat against the spacer, providing a clean standoff without threading into the spacer body itself.

Key Features

• Grade 303 stainless steel construction meeting QQ-S-763 fastener standard for corrosion resistance
• Female unthreaded, round body design accepts M3 screw hardware
• 6 mm overall length with tight length tolerance of -0.13 mm to 0.13 mm for consistent standoff height
• Inside diameter range of 3.2 mm to 3.6 mm with tolerance of 0.000 mm to 0.270 mm
• Bright uncoated finish — no added coating to interfere with clearance fits
• Metric dimensioning suits equipment and assemblies built to international standards

Compatibility

Designed for use in circuit board and electronic enclosure assemblies requiring an M3 metric screw size standoff spacer with a female unthreaded body.

Installation Notes

Installation is typically performed by electronics assemblers or electricians during board mounting or panel assembly. Ensure all power to the assembly is removed before working on or near circuit boards. Use appropriately sized M3 hardware and verify standoff height requirements against the board layout before assembly. Follow applicable electrical codes and equipment manufacturer guidelines when mounting control boards inside HVAC units, panels, or enclosures.
