FAQ Metal Washers, Collars
- Question: What are metal washers and collars?
- Answer: Washers and collars are essential parts in engineering and mechanical applications. They distribute the force of threaded fasteners, such as bolts or screws, to prevent damage and ensure a secure hold. They can also be used as spacers, locking devices and wear pads. Collars are cylindrical spacers used to maintain the position of parts on a shaft or other component.
- Question: How do I choose the right metal washer or collar for my application?
- Answer: When selecting a metal washer or collar, consider the following features: • Inside Diameter (ID): Make sure it matches the diameter of the bolt or shaft. • Outside Diameter (OD): Should be large enough to distribute the force effectively. • Thickness/Length: Must fit the space and load requirements. • Material: Selected based on the application environment (e.g. stainless steel for corrosion resistance). • Surface Treatment: For added protection and durability, a finish such as black oxide or nickel plating is available.
- Question: What material are the metal washers and collars made of?
- Answer: Commonly used materials include: • Stainless Steel: has excellent corrosion resistance and strength • Steel: versatile material, suitable for most applications • Brass: provides good electrical conductivity and corrosion resistance • Aluminum: lightweight and corrosion resistant, ideal for weight-sensitive applications
- Question: What is the difference between standard and precision grade washers and collars?
- Answer: Standard grade washers and collars are suitable for general applications where tight tolerances are not important. However, precision grades provide tighter tolerances and better surface finish, making them ideal for high precision applications where exact dimensions are critical.
- Question: Can I customize the size of the washers and collars?
- Answer: Yes, many suppliers offer customizable options for washers and collars. You can specify inside and outside diameters, thicknesses, and even special features like deep holes or flanged edges to meet the specific needs of your application.
- Question: What is the importance of surface coating on metal washers and collars?
- Answer: Surface treatment can improve the performance and life of washers and collars by enhancing properties such as corrosion resistance, hardness or aesthetics. Common finishes include: • Black oxide: Increases corrosion resistance and reduces light reflection. • Nickel plating: Provides a smooth, shiny surface with good corrosion resistance. • Anodizing: Commonly applied to aluminum to improve corrosion resistance and color.
- Question: How can I be sure that the washer and collar meet my durability requirements?
- Answer: Specify tolerance level when ordering. Standard options include: • Inner diameter tolerance: ±0.05mm to +0.3mm • Outer diameter tolerance: ±0.1mm to ±0.3mm • Thickness tolerance: ±0.01mm to ±0.3mm
- Question: Are there special washers and collars for specific applications?
- Answer: Yes, there are many specialised types available, such as: • Countersunk washers: Designed for use with countersunk screws, allowing the screw to be flush with the face • Flange collars: Provide a larger bearing surface, which distributes forces over a larger area • Hardened washers: Ideal for high load or high wear applications due to their increased hardness
