DIN 1440 A4 Stainless Steel Washer for Clevis Pins, Medium Series
What is a DIN 1440 A4 Stainless Washer for Clevis Pins?
DIN 1440 washers are metric flat washers designed specifically for clevis pin applications, providing a bearing surface around the pin and working with split pins or other retaining elements to secure the assembly. DIN 1440 is the medium series, manufactured to medium tolerances for a tighter and more precise fit around the nominal diameter of the clevis pin.
What is the difference between DIN 1440 and DIN 1441 Washers?
The difference between these two DIN standards is the manufacturing tolerance class. DIN 1440 is the medium series, providing tighter dimensional tolerances and a more precise fit around the nominal clevis pin diameter. DIN 1441 is the coarse series, allowing wider dimensional variations and a looser fit on the pin. DIN 1440 is suited to standard mechanical applications where a predictable fit and moderate bearing surface are important.
What material are DIN 1440 A4 Stainless Washers made from?
These DIN 1440 washers are manufactured from A4 stainless steel, also known as 316 or marine-grade stainless steel. A4 stainless provides superior corrosion resistance to A2 stainless, particularly in environments exposed to saltwater, chlorides, coastal conditions, and persistent moisture.
Where are DIN 1440 A4 Stainless Washers commonly used?
DIN 1440 A4 stainless washers are commonly used with clevis pins in marine equipment, boats and yachts, docks, coastal structures, outdoor machinery, automotive and motorsport equipment, agricultural machinery, industrial equipment, and mechanical linkages.
