Electro Hardware MS1013M17F16F Circuit Board Spacer M4

Product Description

The ELECTRO HARDWARE MS1013M17F16F is a round, female unthreaded circuit board spacer designed to maintain precise separation between PCBs and mounting surfaces in electronic assemblies. Molded from Nylon Grade 101 to MIL-P-17091B specification, this metric spacer accepts an M4 screw and delivers a consistent overall length of 7 millimeters with an outside diameter of 6 millimeters. The inside diameter ranges from 4.2 to 4.8 millimeters, accommodating standard M4 fastener clearance. Its uncoated finish keeps the profile clean and non-conductive. Electronics assemblers, electrical technicians, and panel builders use this type of spacer during PCB mounting operations to control standoff height and prevent board flex or short-circuit contact with enclosure surfaces.

This spacer is suited for use in control panels, industrial electronics enclosures, HVAC control boards, and general PCB assembly work where a lightweight, non-metallic standoff is required. The nylon construction makes it appropriate for environments where electrical isolation between the board and chassis is necessary. At 7 millimeters overall length, it provides a low-profile standoff appropriate for compact assemblies. Minimum order quantity is 10 pieces, sold as individual units per package.

Key Features

• Nylon Grade 101 construction provides electrical isolation and lightweight performance
• Meets MIL-P-17091B fastener standard for consistent dimensional quality
• Female unthreaded bore accepts M4 screw clearance with 4.2 to 4.8 mm inside diameter
• 7 mm overall length with tight length tolerance of -0.13 to 0.13 mm
• 6 mm outside diameter in a round body profile for compact board layouts
• Uncoated bright finish — no added coating to alter dimensional profile or conductivity

Compatibility

Designed as an OEM-style replacement or service component for PCB assemblies requiring M4 metric round nylon spacers with a 7 mm standoff height.

Installation Notes

Installation is performed by electronics assemblers or electrical technicians during PCB mounting. Power down and de-energize all circuits in the enclosure before servicing any board mounting hardware. Insert the M4 fastener through the board and spacer bore without overtightening, as nylon can crack or deform under excessive clamping force. Follow applicable assembly standards and enclosure manufacturer guidelines for PCB standoff torque and spacing requirements.
