Value Collection 03308285 Compression Spring 0.42 in Od

Product Description

The VALUE COLLECTION 03308285 is a small-diameter compression spring manufactured from stainless steel, designed to deliver consistent return force in compact mechanical assemblies. With an outside diameter of 0.42 inches and a free length of 0.50 inches, this spring handles a maximum work load of 2.22 pounds at a spring rate of 6.28 pounds per inch. The 0.028-inch wire diameter keeps the profile tight while maintaining structural integrity under repeated cycling. It is suited for use by mechanical technicians, assembly technicians, and maintenance professionals working on precision equipment, valves, or instrumentation where a reliable small-form compression element is required.

This compression spring fits into applications requiring a hole diameter of 0.4375 inches (7/16 inch) and collapses to a solid height of 0.11 inches. Typical installations include light-duty valve assemblies, instrumentation enclosures, latching mechanisms, and other compact mechanical devices where consistent spring force and corrosion resistance are priorities. Stainless steel construction makes this spring appropriate for environments with exposure to moisture or mild chemical contact. Each package contains 10 springs.

Key Features

• Outside diameter of 0.42 inches fits standard 0.4375-inch (7/16-inch) bore holes
• Spring rate of 6.28 pounds per inch provides predictable, linear force response
• Maximum work load of 2.22 pounds within a compact 0.50-inch free length
• Stainless steel construction resists corrosion in moisture-exposed environments
• Solid height of 0.11 inches allows installation in very shallow cavities
• Sold in packages of 10 for maintenance and service inventory

Compatibility

Designed as a standard compression spring for compact mechanical assemblies requiring a 0.42-inch outside diameter and 0.50-inch free length with a 7/16-inch hole diameter clearance fit.

Installation Notes

Installation is performed by mechanical or maintenance technicians using standard hand tools. Always de-energize and depressurize the assembly before servicing any spring-loaded component. Verify that the mating bore diameter and cavity depth are consistent with the 0.4375-inch hole diameter and 0.11-inch solid height before seating the spring. Do not exceed the rated maximum work load of 2.22 pounds to avoid permanent set or premature fatigue.
