What is BS EN 3043 - Externally threaded fasteners about?
BS EN 3043 is a European standard on aerospace series which covers Fasteners, externally threaded, in heat resisting steel FE PA92HT (A286).
BS EN 3043 specifies the technical and quality assurance requirements for externally threaded fasteners in material FE-PA92HT (A286) of tensile strength class 900 MPa at room temperature, maximum test temperature of material 650 °C.
Who is BS EN 3043 - Externally threaded fasteners for?
BS EN 3043 on externally threaded fasteners is useful for:
- Manufacturers of aerospace equipment and components
- Externally threaded fasteners manufacturers
Why should you use BS EN 3043 - Externally threaded fasteners?
An externally threaded fastener which is prevented from being turned during assembly and which can be tightened or released only by torquing a nut is a bolt. (Example: round head bolts, track bolts, plow bolts.)
The externally threaded fasteners specified here may be manufactured by machining from bar or by forging at the manufacturer's option, if forged there is no requirement for control of grain flow. Primarily for aerospace applications it is applicable to such externally threaded fasteners when referenced on the product standard or drawing.
Heat resistant steels are solid solution strengthened alloy steels for use at temperatures above 500 deg C and upto 750 deg C. As these steels are used over a certain broad temperature ranges, they are normally strengthened by the hardening mechanism of heat treatment, solid solution, and precipitation.
When it comes to the manufacturing and use of aerospace components, reliability and consistent performance are crucial. Hence BS EN 3043 specifies the technical and quality assurance requirements for externally threaded fasteners in material FE-PA92HT (A286). This ensures safety and reliability in your organization and in turn increases the efficiency of work.
