What is BS EN 4499 - 100° countersunk screws about?
BS EN 4499 is a European standard on aerospace series which covers screws, 100° countersunk reduced head, offset cruciform recess, close tolerance normal shank, short thread, in titanium alloy.
BS EN 4499 specifies the characteristics of screws, 100° countersunk reduced head, offset cruciform recess, close tolerance normal shank, short thread, in titanium alloy, anodized, with aluminium pigmented coating.
Who is BS EN 4499 - 100° countersunk screws for?
BS EN 4499 on 100° countersunk screws is useful for:
- Manufacturers of aerospace equipment and components
- 100° countersunk screw manufacturers
Why should you use BS EN 4499 - 100° countersunk screws?
A countersunk screw, also known as a “flat-head screw,” sinks into a surface and rests flush in materials. Similar to other screws, a countersunk head screw has ridges that twist into a material to provide fastening power. Countersunk screws have a flat head instead of a rounded or semi-rounded one.
Titanium alloys are alloys that contain a mixture of titanium and other chemical elements. Such alloys have very high tensile strength and toughness (even at extreme temperatures). They are light in weight, have extraordinary corrosion resistance and the ability to withstand extreme temperatures.
When it comes to the manufacturing and use of aerospace components, reliability and consistent performance are crucial. Hence BS EN 4499 walks you through the characteristics of screws, 100° countersunk reduced head, offset cruciform recess, close tolerance normal shank, short thread, in titanium alloy, anodized, with aluminium pigmented coating. This ensures safety and reliability in your organization and in turn increases the efficiency of work.
