Electro Hardware MS1015M07F16D Round Board Spacer M3

Product Description

The ELECTRO HARDWARE MS1015M07F16D is a round, female unthreaded circuit board spacer designed to maintain precise standoff distance between a PCB and a mounting surface or secondary board. Manufactured from Grade 303 stainless steel to the QQ-S-763 fastener standard, this spacer delivers corrosion resistance and dimensional consistency in electronics assembly and control panel applications. The spacer measures 0.315 inches overall length, accepts an M3 screw through a 0.126 to 0.142 inch inside diameter bore, and presents a 0.236 inch outside diameter round body. It ships uncoated with a bright finish. Electronics assemblers, control board technicians, and industrial equipment builders install this type of hardware during PCB mounting and panel integration work.

This spacer is suited for use in residential and commercial control boards, HVAC equipment PCB assemblies, electrical enclosures, and general electronic equipment requiring a metric M3 standoff. The unthreaded female design allows a fastener to pass through freely, positioning boards at consistent height while isolating them from the mounting substrate. The stainless steel construction makes it appropriate for environments with mild moisture exposure or where ferrous hardware is undesirable.

Key Features

• Grade 303 stainless steel construction per QQ-S-763 fastener standard
• Female unthreaded bore accepts M3 screw, 3.2 to 3.6 mm inside diameter (0.126 to 0.142 inches)
• 8 mm (0.315 inches) overall length with plus or minus 0.130 mm length tolerance
• 6 mm (0.236 inches) outside diameter, round body profile
• Bright uncoated finish — no plating that could affect dimensional tolerance or conductivity
• Minimum order quantity of 10 units

Compatibility

Designed as an OEM-style replacement or assembly component for PCB mounting applications requiring an M3 metric round female unthreaded spacer with an 8 mm standoff height.

Installation Notes

Install and remove circuit board spacers only after de-energizing the equipment and following applicable lockout/tagout procedures per NFPA 70E. Use appropriately sized M3 fasteners and avoid over-torquing, which can crack the PCB substrate or distort the spacer bore. Verify spacer stack height matches the clearance requirements of your board layout before final assembly.
