METAL WASHERS AND COLLARS
Components used in various applications to distribute clamping forces, prevent damage or deformation, and safely secure or join elements.
APPLICATIONS
Metal washers and collars have various applications in different industries and sectors. Below are some of the most common applications:
- Vibration damping and isolation: Washers can absorb and dissipate vibrations generated by machinery, motors or equipment, reducing noise and preventing damage from excessive vibrations.
- Spacers and levelers: Having different sizes and thicknesses, washers are used to adjust the distance between components, level uneven surfaces or compensate for misalignments.
- Automotive industry: Metal collars are used in automobile manufacturing to secure and fix components, such as exhaust pipes, hoses, cables, cooling systems, among others.
These are just a few of the many applications for metal washers and collars. Their versatility and resistance make them indispensable components in a wide variety of sectors and applications.
Example FWSSM-D25-V13.5-T3.0 | MISUMI inCAD Library
In this application the highlighted washer is supporting a spring
that levels the table of the cutting machine.

CONFIGURABLE FEATURES
TYPES
Straight
It is the most common type of washers and collars, this do not have machining exteriors.
Shouldered
It is quite useful since it has supports or flanges at the bottom of the collar.
Square
It is useful when a washer is required that can be manipulated by a wrench.
BORE
Straight
Counterbore
Tapped
Countersunk

MATERIALS & FINISHES
Metal washers and collars can be made from a variety of materials, depending on application requirements and operating conditions. Listed below are the materials you can find at MISUMI.
Carbon steel
- Blued: Black appearance and greatly improves its corrosion resistance Electrodeless Nickel: Yellowish
- Silvery appearance and improves its corrosion resistance, but to a lesser extent than bluing.
- Black chrome: More aesthetic finish and performs very well as a driver.
Aluminum
- Light anodized and dark anodized: Greater resistance against abrasives, increases the durability of aluminum, allows easy cleaning, and does not fade.
