Electro Hardware S333M17F16C Round Pcb Spacer Nylon

Product Description

The ELECTRO HARDWARE S333M17F16C is a round, female unthreaded circuit board spacer designed to provide consistent standoff height and secure two-screw mounting on printed circuit boards. Manufactured from Nylon Grade 101 to MIL-P-17091B specification, this spacer measures 0.875 inches overall length with a 0.1875-inch outside diameter and a 0.089-inch inside diameter, sized for a number 2 screw. It ships uncoated with a bright finish. PCB assembly technicians and electronics maintenance professionals install these spacers to maintain board-to-chassis clearance and prevent contact damage in both production and field-service applications.

This spacer is suited for use in low-voltage electronic assemblies where non-conductive standoffs are required. Common applications include HVAC control boards, electrical enclosures, pool equipment control panels, and general-purpose circuit board mounting. The nylon construction provides electrical isolation between the board and mounting surface, making it appropriate for sensitive electronics in residential and light commercial trade equipment.

Key Features

• Nylon Grade 101 construction per MIL-P-17091B for consistent dimensional and mechanical performance
• Female unthreaded body accepts a number 2 screw for straightforward two-point board mounting
• 0.875-inch overall length with tight length tolerance of -0.005 to 0.005 inches for reliable standoff height
• 0.089-inch inside diameter with tolerance of 0.000 to 0.010 inches for proper screw fit
• Electrically non-conductive nylon material provides PCB-to-chassis isolation
• Uncoated bright finish — no plating to crack, flake, or interfere with close-tolerance assemblies

Compatibility

Designed as an OEM-style replacement or new-installation spacer for circuit boards requiring a number 2 screw, female unthreaded, round nylon standoff with a 7/8-inch overall length.

Installation Notes

Installation is performed by electronics technicians or trade professionals servicing control board assemblies. De-energize all circuits and discharge any capacitors before handling or replacing circuit board hardware. Use hand tools only — over-torquing a number 2 screw into an unthreaded nylon spacer can strip or crack the body. Inspect the mounting surface for debris or burrs before seating the spacer to ensure accurate standoff height.
