2. Key Features of Stainless Steel Split Lock Washers

SS304 (A2) and SS316 (A4) Materials

Stainless steel split lock washers are available in SS304 (A2) and SS316 (A4) material options. SS304 is suitable for many general industrial applications, while SS316 generally offers improved resistance to chloride-containing environments. The appropriate grade depends on the operating environment and project requirements.

Multiple Standard Options

Depending on the required product design and dimensions, reference standards may include GB/T 93, DIN 127A, DIN 127B, and ANSI B18.21.1. The applicable standard should be confirmed against the actual washer type and drawing.

Three Type Options

• Regular Type: DIN 127A / GB/T 93 style for applicable general fastening requirements.

• Heavy-Duty Type: DIN 127B style, with dimensions and thickness determined by the selected specification.

• Light Thin Type: A thinner washer option for equipment designed for lighter loads, subject to specification confirmation.

Natural Stainless Steel Finish

The natural stainless steel finish provides a clean metallic appearance without an additional decorative coating. Surface condition and finish requirements can be confirmed when ordering.

Flexible Industrial Sourcing

Juniq Precision supports specification-based sourcing for stainless steel spring washers used in equipment manufacturing, maintenance, assembly, and industrial hardware distribution.

3. Advantages of Stainless Steel Split Lock Washers

Material Options for Different Environments

SS304 (A2) and SS316 (A4) allow buyers to select stainless steel materials according to their corrosion-resistance requirements. SS316 is often considered for more demanding environments, although material suitability depends on actual exposure conditions.

Different Designs for Different Requirements

Regular, heavy-duty, and light thin types provide options for different assembly designs. Buyers should select the washer according to the applicable standard, dimensions, load conditions, and engineering requirements rather than thickness alone.

Suitable for a Wide Range of Assemblies

Stainless steel split lock washers can be used in selected machinery, cabinets, automotive components, pipe fittings, and general mechanical assemblies where this washer type is specified.

Convenient Specification Matching

By confirming the washer type, material grade, standard, inner diameter, outer diameter, and thickness, buyers can improve specification matching and reduce ordering errors.

Engineering note: A split lock washer should not be assumed to prevent loosening in every bolted joint. Its performance depends on the joint design, preload, loading conditions, and installation method. For vibration-sensitive or safety-critical assemblies, follow the relevant engineering specification.

5. Types of Stainless Steel Split Lock Washers

Regular Stainless Steel Split Lock Washer – DIN 127A / GB/T 93

The regular type is intended for applications where the selected design and standard specify a conventional split spring washer. It may be used in general machinery, cabinet assembly, equipment installation, and routine maintenance.

Choose the regular type based on the specified dimensions, material grade, and fastening design. DIN 127A and GB/T 93 should be checked individually to confirm the required product dimensions and compliance.

Heavy-Duty Stainless Steel Split Lock Washer – DIN 127B

The heavy-duty type is intended for applications requiring the particular dimensions and design associated with the specified DIN 127B product. Buyers should verify the required thickness, dimensions, material, and loading conditions before selection.

A thicker washer does not automatically guarantee higher locking performance. The final selection should follow the engineering design and applicable product specification.

Light Thin Stainless Steel Spring Washer

The light thin type is intended for equipment designs where a thinner spring washer is specified. It may be suitable for selected compact assemblies and light-duty equipment, provided its dimensions and performance meet the application requirements.

When ordering light thin stainless steel spring washers, confirm the available size range, material, and applicable drawing or standard.

6. Applications of Stainless Steel Split Lock Washers

Machinery and Industrial Equipment

SS304 and SS316 split lock washers are used in selected mechanical assemblies, equipment frames, brackets, and machine components. The washer type and material should match the design requirements and operating environment.

Electrical Cabinets and Enclosures

Stainless steel spring washers can be used in cabinet assembly, control enclosures, mounting brackets, and hardware installations where the specified fastener design calls for a split lock washer.

Automotive Assembly and Maintenance

Stainless steel split lock washers may be used in selected automotive assemblies, repair work, and maintenance applications. Always confirm the material, dimensions, and washer type against the vehicle or component manufacturer's requirements.

Pipe Fittings and Mechanical Connections

These washers can be incorporated into suitable bolted connections around pipe supports, brackets, and related equipment. They should not be used as sealing components unless the assembly design specifically requires a compatible sealing solution.

General Assembly and Hardware

Stainless steel split lock washers are also used in general assembly, equipment servicing, industrial hardware, and fastening-product supply. Buyers can specify SS304 (A2) or SS316 (A4) according to project requirements.

7. How to Select and Install Stainless Steel Split Lock Washers

1. Confirm the Fastener Size: Identify the bolt or screw diameter and the required washer dimensions.

2. Select the Material: Choose SS304 (A2) for suitable general environments or SS316 (A4) where its enhanced corrosion resistance is required.

3. Choose the Washer Type: Confirm whether the assembly requires the regular, heavy-duty, or light thin type.

4. Verify the Standard: Check the specified standard and dimensions against the drawing or engineering requirements.

5. Install Correctly: Position the washer beneath the bolt head or nut as specified by the assembly design.

6. Tighten to Specification: Follow the recommended torque and installation procedure for the fastener and joint.

7. Inspect the Assembly: Check that the washer is seated correctly and that the completed joint meets the design requirements.

For assemblies exposed to severe vibration, cyclic loading, or safety-critical conditions, use the locking method specified by the design engineer. A split lock washer is not a universal substitute for a dedicated locking system.
