Electro Hardware MS1013M07F16F Round Circuit Board Spacer

Product Description

The ELECTRO HARDWARE MS1013M07F16F is a round, female unthreaded circuit board spacer designed for M4 screw applications in PCB mounting assemblies. Machined from Grade 303 stainless steel and left uncoated with a bright finish, this spacer meets the QQ-S-763 fastener standard. It measures 7 mm (0.276 inches) in overall length with a 6 mm (0.236 inches) outside diameter and an inside diameter ranging from 4.2 mm to 4.8 mm (0.165 to 0.189 inches). The length tolerance is -0.13 mm to 0.13 mm, and the inside diameter tolerance runs 0.000 to 0.270 mm. Technicians and assemblers use this spacer to maintain precise standoff height and alignment between a circuit board and a mounting surface or chassis.

This spacer is suited for electronic and electromechanical assemblies where corrosion resistance and dimensional accuracy are required. Typical applications include control board mounting in HVAC equipment, electrical enclosures, industrial automation panels, and other environments where a metric M4 fastener pattern is specified. Its stainless steel construction makes it appropriate for installations exposed to moisture or where a non-ferrous coating is undesirable. This is a metric-dimensioned component intended for assemblies designed to M4 hardware specifications.

Key Features

• Grade 303 stainless steel construction per QQ-S-763 fastener standard
• Female unthreaded body accepts M4 screw hardware
• 7 mm (0.276 inches) overall length with tight length tolerance of plus or minus 0.13 mm
• 6 mm (0.236 inches) outside diameter, round body profile
• Inside diameter range of 4.2 to 4.8 mm (0.165 to 0.189 inches) for flexible fit
• Bright uncoated finish — no plating or coating to affect dimensional stack-up

Compatibility

Designed as a metric M4 round circuit board spacer for PCB mounting applications requiring a female unthreaded standoff with a 6 mm outside diameter and 7 mm overall length.

Installation Notes

Installation is typically performed by electronics assemblers or technicians during control board mounting procedures. Ensure the mating surface and screw are M4-compatible before assembly. Power down and de-energize any equipment fully before servicing or replacing circuit board hardware. Avoid over-tightening fasteners through the spacer, as this can distort the board or damage the spacer seat.
