Product Overview
Product Application
DIN 128 B Spring Washer, also known as a wave spring lock washer, is a German standard fastening component designed to provide elastic force and improve the stability of bolted connections. Its wave-shaped profile creates axial spring action, helping maintain contact pressure between fasteners and assembled parts.
Manufactured from spring steel, stainless steel SUS304, or SUS316, DIN 128 B washers are widely used in machinery, automotive components, industrial equipment, and general fastening assemblies where space is limited and continuous preload is required.

Specification
DIN 128 B vs DIN 128 A
DIN 128 B (Wave Spring Washer)
- Wave-shaped profile
- Provides axial spring action
- Suitable for compact assemblies
- Commonly used where space is limited
DIN 128 A (Curved Spring Washer)
- Curved disc design
- Provides bending spring effect
- Often selected for lighter fastening applications
For new engineering designs, alternative locking solutions may be preferred depending on vibration requirements and joint design. DIN 128 standards have also been withdrawn in some applications and replaced by newer locking washer solutions.
Product Advantages
Space-Saving Structure
Compact height makes DIN 128 B suitable for applications where installation space is restricted.
Corrosion Resistant Options
Available in stainless steel grades such as SUS304 and SUS316 for demanding environments.
Common Questions
What is DIN 128 B spring washer?
DIN 128 B is a wave-shaped spring lock washer designed to provide elastic force and improve fastening stability in threaded connections.
Can DIN 128 B washers be reused?
Spring washers may lose elastic properties after repeated compression cycles. Replacement is recommended for critical assemblies.
Does DIN 128 B prevent bolt loosening completely?
No. It improves resistance to loosening by maintaining spring force but cannot replace advanced locking systems in severe vibration conditions.
Can you provide OEM manufacturing?
Yes. We offer customized dimensions, hardness requirements, coatings, laser marking, packaging, and private-label solutions.
