What is BS EN 3912 - Pan head bolts about?
BS EN 3912 is a European standard on aerospace series which covers bolts, pan head, six lobe recess, relieved shank, long thread, in heat resisting steel FE-PA2601 (FE-PA92HT, A286), silver plated.
BS EN 3912 specifies the characteristics of pan head bolts with six lobe recess, relieved shank and long thread, in FE-PA2601 (FE-PA92HT), silver plated, for aerospace applications.
Note: Taking account of the recess geometry, the strength class to be used for the seating torque calculation shall not be greater than 900 MPa.
Who is BS EN 3912 - Pan head bolts for?
BS EN 3912 on pan head bolts is useful for:
- Manufacturers of aerospace equipment and components
- Pan head bolts manufacturers
Why should you use BS EN 3912 - Pan head bolts?
Pan head screws are a common head type of non-countersunk screw head used in wood screws, self-tapping screws, self-drilling screws, and machine screws. They have wide heads, a flat bearing surface, high vertical, chamfered, or curved sides, and a flat or slightly domed top surface with a recessed socket.
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 3912 walks you through the characteristics of pan head bolts with six lobe recess, relieved shank and long thread, in FE-PA2601 (FE-PA92HT), silver plated. This ensures safety and reliability in your organization and in turn increases the efficiency of work.
