FAQs
What does DIN 125A mean?
DIN 125A refers to a German Institute for Standardization (Deutsches Institut für Normung) specification for flat washers. It defines the dimensions, tolerances, and material properties for a standard flat washer, ensuring compatibility with metric fasteners.
Can these washers be used with metal bolts?
Yes, these nylon washers are designed to be used with metal M20 bolts and screws. They serve to protect the surface of the material being fastened and distribute the load.
Are these washers suitable for outdoor use?
Yes, these washers are corrosion-resistant and lightweight, making them suitable for both indoor and outdoor applications.
What is the primary advantage of using nylon washers over metal ones?
Nylon washers are corrosion-resistant, lighter, and can act as insulators and vibration dampeners, while also protecting delicate surfaces from scratching or damage that metal washers might cause.
How many washers are in a box?
Each box contains 100 Unifix Flat Natural Nylon Washers.
What size fasteners do these washers fit?
These washers are specifically designed for M20 size fasteners.
Troubleshooting
Washer does not fit onto the bolt.
Ensure you are using an M20 bolt. This washer is specifically sized for M20 fasteners according to DIN 125A standards.
Washer appears to be cracking or degrading.
Check for exposure to extreme temperatures or harsh chemicals, which can degrade nylon. Store in a moderate environment. If widespread, consider if the application environment is suitable for nylon.
Fastening feels loose despite tightening.
Ensure the washer is properly seated and not hindering the bolt's thread engagement. Verify that the bolt and nut are the correct size and are properly tightened for the application's load requirements.

Setup, Compatibility & Care
Setup: These washers require no special setup. Simply place them onto an M20 bolt or screw before inserting it through the material you wish to fasten. Ensure the washer lies flat against the surface.
Compatibility: These washers are designed specifically for M20 bolts and screws, adhering to the DIN 125A standard. They are compatible with any M20 fastener that requires a flat washer of this size.
Care: As these washers are made of nylon and are corrosion-resistant, they require minimal care. Keep them stored in a dry place to prevent accumulation of dust or debris. If they become dirty during use, they can be easily cleaned with a damp cloth. Avoid prolonged exposure to harsh chemicals or extreme temperatures that could degrade the nylon material over time.
