Electro Hardware S333M07F16E Round Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S333M07F16E is a round, female unthreaded circuit board spacer designed to provide precise standoff clearance between a PCB and a mounting surface. Built from Grade 303 stainless steel with a bright uncoated finish, this spacer meets the QQ-S-763 fastener standard. It accepts a 4 screw and measures 0.875 inches overall length, with a 0.1875 inch outside diameter and a 0.116 inch inside diameter. The length tolerance is held to plus or minus 0.005 inches, and the inside diameter tolerance runs 0.000 to 0.010 inches, making it suitable for installations where consistent board standoff height is required.

This spacer is used in electronic control board assemblies found in HVAC equipment, pool controls, electrical panels, and other trade-grade enclosures. It is appropriate for any application requiring a small-format, corrosion-resistant standoff on a 4 screw pattern. The stainless steel construction makes it a reliable choice in environments where moisture exposure or chemical contact is a concern, such as outdoor electrical enclosures or equipment rooms with high humidity.

Key Features

Compatibility

Designed as an OEM-style replacement or service spacer for circuit board assemblies using a 4 screw pattern with a female unthreaded standoff in the inch measurement system.

Installation Notes

Circuit board spacers of this type are typically installed by electricians or electronics-trained HVAC technicians during control board replacement or panel assembly. Always de-energize and lock out the equipment before handling PCBs or fasteners inside an enclosure. Use the correct 4 driver to avoid stripping the screw threads during installation. Follow applicable NEC guidelines for work inside electrical enclosures.
