Electro Hardware MS1001M17F16D Round Circuit Board Spacer

Product Description

The ELECTRO HARDWARE MS1001M17F16D is a round, female unthreaded circuit board spacer designed to maintain precise standoff clearance between a PCB and a mating surface. Sized for M3 screw hardware, this spacer is molded from Nylon Grade 101 and meets MIL-P-17091B fastener standards. It measures 1.0 mm overall length (OAL) with an outside diameter of 6.0 mm and an inside diameter ranging from 3.2 to 3.6 mm. The uncoated finish keeps the part electrically neutral and free of metallic contamination near sensitive circuit traces. Electronics assemblers and electrical technicians install this spacer during PCB mounting operations in industrial, commercial, and military-grade assemblies.

This spacer is suited for applications where compact vertical clearance is required and where non-conductive hardware is preferred to prevent short circuits or galvanic corrosion on circuit boards. The metric sizing makes it appropriate for PCB assemblies built to metric design standards. Its Nylon construction performs well in low-load, low-temperature mounting configurations typical of control board assemblies, relay panels, and general electronics enclosures.

Key Features

• Female unthreaded body accepts M3 screw hardware for secure PCB standoff mounting
• Nylon Grade 101 construction provides electrical insulation and resists galvanic interaction with board traces
• 1.0 mm OAL with a length tolerance of -0.130 to 0.130 mm for consistent stack height
• 6.0 mm outside diameter with a 3.2 to 3.6 mm inside diameter range accommodating standard M3 clearance holes
• Uncoated bright finish — no added materials that could contaminate PCB surfaces
• Meets MIL-P-17091B fastener standard for use in military and high-reliability assemblies

Compatibility

Designed as an OEM-style PCB standoff spacer for metric circuit board assemblies requiring M3 screw hardware and a non-conductive round spacer with a 6.0 mm outside diameter.

Installation Notes

Installation is performed by electronics assemblers or licensed electricians during PCB mounting or panel assembly. Power down and de-energize all circuits before servicing any board on which this spacer is installed. Standard ESD precautions should be observed when handling circuit boards and mounting hardware. Do not overtighten M3 fasteners against the nylon body, as excessive torque can crack or deform the spacer.
