Electro Hardware S333M07F16C Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S333M07F16C is a round, female unthreaded circuit board spacer designed to maintain precise separation between printed circuit boards and mounting surfaces in electronic assemblies. Machined from Grade 303 stainless steel to the QQ-S-763 fastener standard, this spacer delivers corrosion resistance and dimensional consistency in demanding environments. It accommodates a No. 2 screw size with a 0.089 inch inside diameter and measures 0.1875 inches in outside diameter. The overall length of 0.875 inches provides reliable board standoff height. The bright, uncoated finish requires no additional surface preparation before installation.

This spacer is suited for use in HVAC control boards, electrical enclosures, pool equipment electronics, and other applications where a No. 2 fastener is used to secure circuit boards to a chassis or panel. The round body shape and female unthreaded design allow for straightforward stack-up assembly during initial builds and service replacements. It is sold individually and is appropriate for both OEM production environments and field repair work performed by licensed electricians or electronics technicians.

Key Features

• Grade 303 stainless steel construction meets QQ-S-763 fastener standard for consistent material properties
• Female unthreaded, round body accepts No. 2 screw fasteners with 0.089 inch inside diameter
• Overall length of 0.875 inches with a tight length tolerance of -0.005 to 0.005 inches
• Outside diameter of 0.1875 inches with inside diameter tolerance of 0.000 to 0.010 inches
• Bright, uncoated finish — no plating or coating to affect dimensional fit
• Lightweight at 0.01 pounds, suitable for high-density board assemblies

Compatibility

Designed as an OEM-style replacement or new-installation spacer for circuit board assemblies that use No. 2 screw fasteners and require a 0.875 inch standoff height.

Installation Notes

Installation is typically performed by a licensed electrician or qualified electronics technician. De-energize and lock out the equipment before handling any circuit board assembly. Use the correct No. 2 fastener to avoid exceeding the inside diameter tolerance and distorting the spacer bore. Verify standoff height requirements against board layout specifications before finalizing stack-up.
