spring steel washers exporter for Locking, Spacing, and Load Support
XZ Fastener exports spring steel washers for assemblies that need elastic preload, vibration resistance, controlled spacing, and load support. Products can be supplied as split lock washers, wave spring washers, serrated lock washers, curved washers, conical spring washers, and custom stamped washers according to order requirement. Buyers can specify standard, size, material grade, hardness, heat treatment, coating, packaging, inspection level, and shipment terms. Spring steel washers can be exported 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 should be specified by more than size. Buyers need to confirm washer type, spring action, hardness range, heat treatment, surface coating, packing format, 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 dimensions but behave differently under bolt preload.
For anti-loosening applications, buyers may 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 export orders, spring steel washers should be matched with the correct fastener grade, coating, carton label, and inspection requirement before production confirmation.
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 export 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, packing labels, and carton details according to the purchase order. Buyers who need traceable checks can refer to XZ Fastener’s fastener quality control notes when preparing inspection requirements.

Automotive Hardware
Used in repair kits, brackets, covers, and non-critical fastening points where washer elasticity is useful.
Electrical Cabinets
Serrated and spring washers can be used in cabinet hardware, grounding points, and panel assemblies according to design needs.
Agricultural Equipment
Commonly used in equipment that faces vibration, repeated maintenance, and outdoor operating conditions.
Export Fastener Kits

How to Get a Faster Quotation
For standard spring steel washers, send the standard number, size, material grade, hardness requirement, finish, quantity, packaging method, and destination details if available. 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 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.
