What is BS EN 4691-1 - Tie Rod with integrated bolts about?  
BS EN 4691-1 is the first part of the multi series European standard that specifies the required characteristics, inspection, and test methods, qualification and acceptance conditions for rod assemblies with two adjustable ends with integrated bolts, designed to withstand static and dynamic loads possible for interior and substructure in the temperature range from − 55 °C to 85 °C. It is applicable whenever referenced.
For a complete overview see EN 4691-2.
Who is BS EN 4691-1 - Tie Rod with integrated bolts for? 
BS EN 4691-1 on tie rod with integrated bolts is useful for:  
- Aerospace parts manufacturers  
- Tie Rod with integrated bolts manufacturers 
Why should you use BS EN 4691-1 - Tie Rod with integrated bolts?  
A tie rod or tie bar (also known as a hanger rod if vertical) is a slender structural unit used as a tie and (in most applications) capable of carrying tensile loads only. It is any rod or bar-shaped structural member designed to prevent the separation of two parts, as in aerospace series. 
Bolts are one of the most versatile structural fasteners, available in a vast array of configurations to suit different materials and strength requirements. These fasteners differ primarily in thread specification, length, and head shape, with varying combinations of these characteristics resulting in bolts with different functions. 
BS EN 4691-1 provides technical specification, procedures, and measurement requirements for manufacturing Tie rods with integrated bolts
BS EN 4691-1 provides the construction kit of rod assemblies for aerospace applications with two adjustable ends with integrated bolts for interior and substructure. This can benefit you by the use of this information in various aerospace applications. This can help you increase safety in operations.
