Who is BS EN 3820 - Normal hexagonal head bolts for?
BS EN 3820 on normal hexagonal head bolts is useful for:
- Aerospace parts manufacturers
- Bolts manufacturers
- Titanium alloy manufacturers
Why should you use BS EN 3820 - Normal hexagonal head bolts?
Hexagon bolts are a type of threaded bolt, characterised by their six-sided hexagonal-shaped head. Hex bolts can be either fully threaded or partially threaded (featuring a clear shank along part of the body) and are suitable for use in a wide range of applications, typically machinery and construction.
They are available in a choice of types, sizes, materials and finishes, providing the freedom and flexibility to select the bolt best suited to your particular task or application. Hex bolts are sometimes also known as hex head bolts or hexagon bolts, again due to their distinctive head shape.
With the help of BS EN 3820 specifies the characteristics of normal hexagonal head bolts which have coarse tolerance normal shank and a short thread in titanium alloy, you can benefit from the use of the information in various aerospace applications. This can help you increase safety in operations.
