Spring washer or Cut washer

Spring Washers, also known as Cut Washers or Split Lock Washers, are specially designed fastening components traditionally used in bolted assemblies where the approved specification calls for a split spring washer. Their split-ring design creates tension between the fastener and surface, with actual performance depending on the joint design and installation conditions in mechanical, automotive, construction, and industrial applications.

Identification and Selection

• Split-ring profile, also described as a cut washer or split lock washer.
• Select the nominal fastener size and check inner diameter, outer diameter, section and applicable standard.
• Specify the required material and finish according to the drawing and service conditions.
• Use only where the approved joint specification permits this washer design.
• Do not assume that a split spring washer prevents loosening in high-vibration or safety-critical assemblies.
• Confirm compatibility with the joint preload, mating surfaces and installation requirements.

Spring Washer / Cut Washer Specifications

For procurement enquiries, “cut washer” is commonly used for a split spring washer. To avoid a mismatch, specify the nominal bolt size, washer material, finish or coating, applicable standard or profile where known, and quantity.

• Nominal bolt or thread size
• Material or grade where specified
• Finish or coating requirement
• Washer standard, dimensions or drawing where applicable
• Quantity and delivery location

Applications and Selection

Spring washers or cut washers are used in bolted assemblies across construction, fabrication, machinery and maintenance requirements. Suitability depends on the joint design and project specification. For vibration-sensitive or safety-critical joints, use the locking method and washer specification required by the approved design rather than substituting by name alone.

Types, Materials and Ordering Details

In trade enquiries, cut washer, spring washer and split lock washer often refer to the same split-ring style. Other locking washer designs, such as serrated, wedge-lock and disc spring washers, are not direct equivalents; the required design must be specified.

When requesting a quotation, confirm the nominal bolt size, inner and outer washer diameters, thickness or section, applicable drawing or standard, and whether the requirement is metric or inch-series. Specify the material and any surface finish separately (for example, carbon steel, stainless steel, zinc coating or hot-dip galvanizing as applicable to the project). These are selection examples, not a statement of current stock availability.

Split spring washers are not a universal solution against loosening, particularly in heavily preloaded or vibration-critical joints. Follow the project engineer’s approved locking method and washer specification for structural or safety-critical installations.
