Spring steel washers can be ordered as individual bulk items or combined with bolts, nuts, screws, and related fastener products for machinery, electrical, automotive, and maintenance purchasing.
Quick Specs
What Buyers Should Know Before Sourcing Spring Steel Washers
Spring steel washers are not selected only by inner diameter, outer diameter, and thickness. Buyers should also confirm washer type, spring action, hardness range, heat treatment, surface coating, and whether the assembly needs locking, load compensation, or electrical contact. A split lock washer, a wave spring washer, and a conical spring washer may share similar sizes but work differently under bolt preload.
For anti-loosening applications, buyers may also compare split lock washers and serrated lock washers. For made-to-drawing parts, special preload, or non-standard stamping shapes, XZ Fastener can review drawings through its custom fasteners service.

For general washer sizing and application comparisons, buyers can review XZ Fastener’s flat washer sizing and material guide before preparing a spring washer inquiry.
Material and Grade Explanation
Spring steel washers are normally produced from high-carbon or alloy spring steel that can be hardened and tempered to provide elastic recovery. 65Mn is commonly used for many spring washer types. 60Si2Mn may be considered where higher spring performance is required. SK5 and C75S are also used for selected stamped spring parts according to drawing and buyer requirements.
Material choice should be reviewed together with washer geometry, heat treatment, hardness, coating, and assembly load. For custom washers or non-standard spring behavior, buyers can prepare drawings and material notes using XZ Fastener’s guide on made-to-drawing fastener material requirements.
Surface Finish Selection Guide
- Plain oiled: Common for indoor stock, short-term protection, and simple factory use.
- Black oxide: Often selected for machinery assemblies where dark appearance and light oil protection are acceptable.
- Zinc plated: Used for general corrosion resistance, with post-treatment considered for high-hardness parts.
- Phosphate and oil: Suitable for some mechanical assemblies requiring a darker, oil-retaining finish.
- Mechanical zinc: Can be considered where reduced hydrogen embrittlement risk is important.
- Geomet type coatings: Available upon request for selected corrosion resistance requirements.
- Hot dip galvanized matching: If washers are supplied with hot dip galvanized DIN 933 bolts, dimensional fit and coating suitability should be confirmed before order release.
Manufacturing and Quality Control
Spring steel washer production can include raw material preparation, stamping, cutting, forming, heat treatment, tempering, deburring, coating, sorting, and packing. The most important process points are stable material, correct forming, controlled hardness, clean edges, and coating that matches the working environment. For electroplated high-hardness spring washers, post-plating treatment can be specified according to order requirement.
XZ Fastener checks incoming material, production dimensions, hardness, visual appearance, coating condition, and packing details according to the purchase order. Buyers who need traceable checks can refer to XZ Fastener’s raw material inspection process and fastener quality control notes when preparing inspection requirements.

How to Get a Faster Quotation
For standard spring steel washers, send the standard number, size, material grade, hardness requirement, finish, quantity, and packing method. For custom washers, include a drawing, sample photo, thickness, free height, wave height, serration details, tolerance, burr direction, heat treatment requirement, and coating requirement. If the washer is supplied with bolts or nuts, provide the mating fastener grade and finish so fit and coating compatibility can be checked.
For production and export orders, clear labels, separated sizes, carton weight limits, pallet requirements, and inspection documents help reduce confirmation time. Buyers can contact XZ Fastener with drawings and order details for review.
