RIB Washers

  • Rib Washer drawing

RIB washers are a type of serrated conical disc spring washer used to prevent threaded fasteners from loosening. Their serrated teeth help them dig into mating surfaces and form secure connections, even against vibration. At Metric & Multistandard, we supply a variety of metric washers to meet your needs.

Our selection of RIB washers includes the Type “S” series (for fasteners with Property Class less than 8.8) and the Type “VS” series (for fasteners with Property Classes 8.8 and 10.9). Our RIB washers are genuine Schnorr® safety spring washers, made from Schnorr spring steel and available with either black or zinc plating. We are proud to supply top-quality RIB washers for regular or heavy-duty applications.

RIB Washer Applications and Benefits

Applications of Rib Spring Washers

RIB washers and conical disc spring washers are designed to withstand heavy-duty, high-load, or vibration-prone applications:
  • Automotive assemblies: Engines, chassis
  • Construction projects: Structural engineering, cabinetry
  • Machinery: Industrial machines, outdoor equipment

Benefits of Rib Spring Washers

The serrated “rib” design of these washers offers many advantages:
  • Superior load distribution
  • Pull-through prevention
  • Mating surface protection
  • Vibration and loosening resistance
  • Increased longevity of connections
  • Consistent and durable results

Using and Installing RIB Washers

While RIB washers can be used for a variety of applications, they are commonly paired with socket head cap screws. Their serrated and conical shape allows them to create a locking force on the screws, reducing the risk of loosening and enhancing load distribution. Socket head cap screws are designed for high-stress applications, making RIB washers an excellent solution for preventing loosening.
