What is BS EN 6105 - Stud about ?
BS EN 6105 is a European standard on aerospace series that covers stud with shoulder.
BS EN 6105 specifies the dimensions, tolerances, required characteristics and mass of a stud for use in fuselage interior equipment and structural applications.
BS EN 6105 shall be used in conjunction with retaining washer per EN6090A01 (conform to EN 6090) and receptacles per EN 6092 or EN 6093.
Who is BS EN 6105 - Stud for ?
BS EN 6105 on stud is useful for: 
- Aerospace parts manufacturers
- Stud with shoulder manufacturers
Why should you use BS EN 6105 - Stud ?
Aerospace studs are a combination - a hybrid - between a bolt and a screw. One end of a stud functions as a bolt and the other functions as a screw.
Aerospace studs are the preferred fastener in many heavy-duty applications, from propulsion systems to helicopters. Because they do not rotate during tightening — the nut is tightened instead — studs make it easier to achieve highly accurate torque values and reduce the chance of the main cap walking. For the same reason, studs also cause less wear and tear to the block’s threads and thereby extend its serviceable life.
With the help of BS EN 6105 which specifies the dimensions, tolerances, required characteristics and mass of asud with shoulder, you can achieve various structural applications as well as applications in fuselage interior equipment, these are crucial parts of an airplane. BS EN 6105 will provide you with the best practices for the use of retaining washers.
