Value Collection SW7BX0400-100BX Wave Disc Spring M4

Product Description

The VALUE COLLECTION SW7BX0400-100BX is a metric wave disc spring manufactured from 18-8 stainless steel. Wave disc springs store and release energy along their axis, providing consistent load compensation in fastener assemblies, bearing preload applications, and precision mechanical joints. This spring measures 4.3 mm inside diameter, 9 mm outside diameter, 2 mm overall height, and 0.5 mm thickness. It is sized for M4 screw applications. Machinists, maintenance technicians, and mechanical assemblers install this type of hardware in equipment where controlled deflection and vibration damping are required in tight axial spaces.

This wave disc spring is suited for use in compact metric fastener assemblies across industrial, commercial, and OEM manufacturing environments. Its 18-8 stainless steel construction provides corrosion resistance appropriate for washdown, outdoor, or moderately corrosive service conditions. Typical installation scenarios include bearing retention systems, valve assemblies, instrumentation hardware, and any application requiring a low-profile spring element aligned to an M4 fastener. This product is sold in multiples of 100 units minimum order quantity with a package quantity of 1.

Key Features

• 18-8 stainless steel construction for corrosion resistance in demanding environments
• M4 screw size compatibility for direct use in metric fastener assemblies
• Low-profile 2 mm overall height suits tight axial clearance applications
• 0.5 mm material thickness provides consistent spring rate and deflection characteristics
• Metric dimensioning throughout for use in ISO-standard mechanical assemblies
• UNSPSC Code 31161830 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement or original-fit wave disc spring for metric M4 fastener assemblies requiring a 4.3 mm inside diameter and 9 mm outside diameter spring element.

Installation Notes

Wave disc springs are installed by mechanical assemblers and maintenance technicians working on precision equipment. Power down or de-energize any equipment before disassembling fastener or bearing assemblies. Ensure mating surfaces are clean and free of burrs to avoid altering spring load characteristics. Do not exceed the designed deflection range, as over-compression can permanently deform the spring and reduce its effectiveness.
