Electro Hardware S1335-M07-F16-K Circuit Board Spacer

Product Description

The ELECTRO HARDWARE S1335-M07-F16-K is a round, female unthreaded circuit board spacer machined from 18-8 and 303 grade stainless steel. It accepts a 1/4 inch screw and measures 0.125 inches in overall length, with an inside diameter of 0.257 inches and an outside diameter of 0.500 inches. The uncoated finish meets QQ-S-763 fastener standards. This spacer is used to maintain precise standoff clearance between a circuit board and a mounting surface, preventing electrical shorts and ensuring proper airflow and vibration isolation in control assemblies. Electricians, HVAC technicians, and electronics service professionals install this hardware during control board replacements or panel fabrication.

This spacer is suited for residential and commercial control board assemblies where a low-profile, corrosion-resistant standoff is required. Its compact 1/8 inch overall length makes it appropriate for tight chassis installations where vertical clearance is limited. The stainless steel construction resists corrosion in environments that may be exposed to moisture or mild chemicals, making it a reliable choice for HVAC equipment enclosures, electrical control panels, and similar trade applications.
