Classification: 1100 MPa/425 °C
Who is BS EN 4849 - 1100 MPa/425 °C titanium screws for?
BS EN 4849 on screw, 100° countersunk normal head, Spiral Drive Recess, close tolerance normal shank, short thread, in titanium alloy, aluminium IVD coated. Classification: 1100 MPa (at ambient temperature)/425 °C is useful for:
- Manufacturers of hardware tools for the aerospace sector
- Quality control personnel
- Testing and inspection personnel
Why should you use BS EN 4849 - 1100 MPa/425 °C titanium screws?
Fasteners used for aerospace applications withstand varying changes in temperature. Any fault in their design, composition and physical capabilities could result in their failure. This could be potentially hazardous and compromise the aircraft’s safety.
BS EN 4849 specifies the physical requirements such as dimensions, tolerances and lubrication for these fasteners to ensure they are well designed and function as intended. BS EN 4849 also provides you with designation guidelines that can help your consumers identify the correct fastener.
Overall, the guidelines of BS EN 4849 enable you to design and manufacture fasteners that could withstand a temperature of 1100 MPa1/425 °C2.
