What is BS EN 470203 - Stud - quick-release and locking about?
BS EN 4702‑03 is part two of a multi-series of European standards on quick-release fastening systems for non-structural and lining applications which covers stud - quick-release and locking.
BS EN 4702‑03 specifies the dimensions, mass, tolerances and static values of stud – quick-release and locking for use in fuselage interior equipment and non-structural or secondary structural area.
Who is BS EN 470203 - Stud - quick-release and locking for?
BS EN 470203 on stud - quick-release and locking is useful for: 
- Aerospace parts manufacturers
- Non-structural and lining application professionals
- Stud - quick-release and locking manufacturers
Why should you use BS EN 470203 - Stud - quick-release and locking?
The quick release fasteners are maintenance-free, vibration-resistant and have a captive seal to prevent loss. It comprises a hardened steel locking bolt, a plastic retainer and a spring steel slip-on lock bottom.
A threaded rod, also known as a stud, is a relatively long rod that is threaded on both ends; the thread may extend along the complete length of the rod. They are designed to be used in tension.
Aerospace studs are a combination between a bolt and a screw. One end of a stud functions as a bolt and the other functions as a screw.
Fuselage interior equipment and non-structural or secondary structural area are very important aerospace applications and with the help of BS EN 4702‑03 which describes the dimensions, mass, tolerances and static values of stud – quick-release and locking, you can make this process easier
