Product Information

Full details

The SS8 Spring Lock Washers - M18 are essential components for professionals and DIY enthusiasts who need to secure heavy-duty bolted connections against vibration and dynamic loads. These silver-tone washers provide a continuous radial force to maintain fastener integrity across industrial, automotive, and construction projects, though they are specifically sized for M18 hardware and are not suitable for smaller or larger bolt diameters.

FAQs

Can these be reused after being removed?

It is generally recommended to replace spring lock washers after they have been fully compressed during a heavy-duty installation to ensure maximum locking integrity.

Are these stainless steel?

The SS8 line is designed for reliable performance; please refer to the product specification for specific material certifications if corrosion resistance in extreme environments is a requirement.

What does the M18 designation mean?

M18 refers to the metric diameter of the bolt (18mm) that this specific washer is designed to accommodate.

Should I use a flat washer with this?

In many applications, using a flat washer underneath the spring lock washer can help protect the mounting surface from indentations caused by the spring coil.

Can I use these for electrical connections?

Yes, they are suitable for electrical installations where vibration-proof connections are required, provided they do not interfere with the electrical contact surface.

Troubleshooting

Bolt still feels loose after tightening

Verify the bolt is torqued to the correct specification for the application and ensure the washer is not flattened or damaged.

Washer does not sit flush against the surface

Check the bolt thread and the mounting hole for debris; clean the surface to ensure a flat, stable contact area.

Difficulty fitting the washer over the bolt

Confirm that your bolt is exactly M18; the washer is designed for a precision fit and will not accommodate oversized hardware.

Pros and Cons

Pros

  • Increases friction to prevent bolt loosening
  • Enhanced load distribution through square profile
  • Suitable for demanding industrial and marine applications
  • Durable silver-tone finish for consistent performance

Cons

  • Specific to M18 hardware size only
  • Not intended for high-tension applications requiring specialized locking nuts
  • Requires proper torque application to be fully effective

Setup, Compatibility & Care

To install, slide the M18 spring lock washer onto your M18 bolt before inserting the bolt into the assembly. As you tighten the fastener, the washer will compress, creating the required friction against both the bolt head and the mating surface. Compatibility is strictly limited to M18 bolts; attempting to use these on smaller bolts will prevent them from engaging correctly, while larger bolts will not fit through the inner diameter. For care, inspect the washers during routine maintenance; if a washer has been permanently deformed or flattened due to over-tightening or excessive vibration, replace it with a new unit to ensure the locking mechanism remains effective.
