DIN 1441 A4 Stainless Steel Washer for Clevis Pins, Coarse Series
What is a DIN 1441 A4 Stainless Washer for Clevis Pins?
DIN 1441 washers are metric flat washers designed for use with clevis pins and retaining hardware, providing a bearing surface around the pin and helping distribute load through the assembly. DIN 1441 is the coarse series, manufactured with wider dimensional allowances than the medium DIN 1440 series, resulting in a looser fit around the nominal clevis pin diameter.
What is the difference between DIN 1440 and DIN 1441 Washers?
The difference between DIN 1440 and DIN 1441 is the manufacturing tolerance class. DIN 1440 is the medium series, providing tighter tolerances and a more precise fit around the nominal diameter of the clevis pin. DIN 1441 is the coarse series, providing wider tolerances and a looser fit. DIN 1441 is a good choice for heavy-duty or less precise applications where coarse tolerances are acceptable or where greater variation in mating components is expected.
What material are DIN 1441 A4 Stainless Washers made from?
These DIN 1441 washers are manufactured from A4 stainless steel, also known as 316 or marine-grade stainless steel, providing excellent resistance to corrosion in demanding environments. A4 stainless is particularly effective against saltwater, chlorides, moisture, and coastal exposure, making it an excellent choice for marine and outdoor equipment.
Where are DIN 1441 A4 Stainless Washers commonly used?
DIN 1441 A4 stainless washers are commonly used with clevis pins in marine equipment, boats and yachts, docks, coastal structures, agricultural machinery, construction equipment, outdoor machinery, trailers, automotive equipment, industrial machinery, and heavy-duty mechanical linkages.
