FAQ:
Q1: What is a DIN 125 Flat Washer used for?
A: DIN 125 Flat Washer is used to distribute load under a bolt head or nut, protecting the surface material and improving joint stability in fastening applications.
Q2: What is the difference between DIN 125 and a "Standard" washer?
A: DIN 125 is a specific German technical standard (often harmonized with ISO 7089) that defines exact inner diameters, outer diameters, and thicknesses. Using a standardized DIN 125 Flat Washer ensures that the component will fit perfectly with any metric bolt of the same nominal size, regardless of the manufacturer.
Q3: Why use 304 stainless steel for flat washers?
A: 304 stainless steel (also known as A2) is the most versatile and widely used grade in the fasteners industry. It provides an excellent balance of strength and corrosion resistance for most general-purpose applications, including food service and architectural projects.
Q4: Can these washers prevent bolts from loosening?
A: While a flat washer primarily distributes load and protects the surface, it does not function as a locking mechanism. For high-vibration environments where loosening is a concern, we recommend pairing these with a spring washer or a lock nut.
Q5: Are these washers suitable for heavy-duty structural steel?
A: Yes. Because they comply with established standards, they offer the mechanical strength consistency required for industrial safety. However, for high-temperature or extremely corrosive marine environments, you may wish to consider our 316 (A4) grade options.
