Value Collection SW7BX0300-200BX Wave Disc Spring M3

Product Description

The VALUE COLLECTION SW7BX0300-200BX is a metric wave disc spring manufactured from 18-8 stainless steel. Wave disc springs store and release energy under axial load, providing consistent deflection in tight radial spaces where conventional coil springs will not fit. This spring measures 8 mm outside diameter, 3.2 mm inside diameter, and 1.6 mm overall height, with a 0.50 mm thickness. It is sized for M3 screw applications. Maintenance technicians, assembly engineers, and precision equipment specialists install these springs in mechanical subassemblies requiring controlled preload or end-play elimination.

This wave disc spring is suited for compact fastener assemblies, bearing preload applications, electrical connectors, and precision instruments where axial space is limited. The metric sizing and M3 compatibility make it a practical choice for light-duty industrial, electronic, and instrumentation assemblies. The stainless steel construction provides corrosion resistance in moderate-exposure environments. This SKU is sold as a single piece with a minimum order quantity of 200 units, making it appropriate for production and maintenance stocking requirements.

Key Features

• 18-8 stainless steel construction offers corrosion resistance and reliable spring-back in repeated-load cycles
• 8 mm outside diameter and 3.2 mm inside diameter sized for M3 fastener applications
• 1.6 mm overall height and 0.50 mm thickness suit assemblies with minimal axial clearance
• Metric dimensioning aligns with ISO-standard hardware and metric fastener systems
• Wave profile distributes load evenly across the seating surface, reducing point stress on mating components

Compatibility

Designed for use with M3 metric fastener assemblies. Suitable as a wave-style disc spring in light-duty mechanical, electronic, and instrumentation applications requiring an 8 mm OD metric spring element.

Installation Notes

Installation is typically performed by assembly technicians or maintenance personnel using hand tools appropriate for M3 hardware. Ensure mating bore and shaft surfaces are clean and free of burrs before seating the spring. Confirm axial load requirements against the spring rate before assembly, as wave disc springs are sensitive to stack orientation and quantity. Follow applicable equipment manufacturer guidelines for preload torque and fastener sequencing.
