BS EN 4234:2020

What is BS EN 4234 about?  

BS EN 4234 specifies the characteristics of worm drive clamps designed for use with suitable rubber hoses to form joints in fluid system pipelines for aerospace applications. 

Who is BS EN 4234 for? 

BS EN 4234 on the characteristics of worm drive clamps is useful for:  

• Worm drive clamps manufacturers  
• Aircraft ventilation system professionals   
• Structural engineers 

Why should you use BS EN 4234? 

Worm drive clamps mainly consist of four components viz. the captive screw, housing, band & underlap. When the screw is turned, it acts as a worm drive pulling the threads of the band, causing the band to tighten around the hose. 

Aerospace clamps are used in a wide range of applications, including power connections, cable looms, aircraft ventilation and other connections on the aircraft. 

Some characteristics of worm drive clamps are: 

• High tensile quality of hard S.S. band the threads are extremely strong to withstand stresses of high worm Screw driving torque. 
• Corrosion-resistant stainless steel material for all components keeps the gear mechanism smooth and intact even after using it for a longer time frame. 

BS EN 4234 gives all the details on the required characteristics, designation, marking, technical specification and qualification of worm drive clamps designed for use with suitable rubber hoses, which will give you a solid base to start with and reduce the risk of safety and increase credibility for the aerospace industry. Owing to the above characteristics, worm drive clamps can help aerospace series by providing high reliability and increased safety for aeroplane passengers.
