BS EN 3685 is a European standard on aerospace series that covers technical specification on Bolts in heat resisting steel FEPA2601 (A286) – Classification: 1 100 MPa/650 °C.
BS EN 3685 specifies the technical specification, qualification and quality assurance requirements for bolts in material FE–PA2601 (A286) of tensile strength class 1 100 MPa at room temperature, maximum test temperature of material 650 °C.
BS EN 3685 on Bolts in heat resisting steel FEPA2601 (A286) is useful for:
Aircraft quality bolts are made from alloy steel, stainless or corrosion resistant steel, aluminum alloys and titanium. Within our industry the first two are the most common. Aircraft bolts will always have a marking on their head.
Primarily for aerospace applications BS EN 3685 is applicable to such bolts when referenced on the product standard or definition document.
With the use of BS EN 3685 you get to know the technical specification, qualification, and quality assurance requirements of bolts in material FE–PA2601 (A286) of tensile strength class 1 100 MPa at room temperature which can be very helpful for use in aerospace applications.
