What is BS EN 4128 - Hexagonal head bolts about?
BS EN 4128 is a European standard on aerospace series that covers normal hexagonal head bolts with a coarse tolerance shank and short thread in heat resisting nickel base alloy.
BS EN 4128 specifies the characteristics of bolts, normal hexagonal head, coarse tolerance shank, short thread, in heat resisting nickel base alloy, aluminium IVD coated.
Who is BS EN 4128 - Hexagonal head bolts for?
BS EN 4128 on hexagonal head bolts is useful for: 
- Aerospace parts manufacturers
- Hexagonal head bolts manufacturers
Why should you use BS EN 4128 - Hexagonal head bolts?
Hexagon head cap screws, also called hex bolts or hex head cap screws, are threaded fasteners with a six-sided head. They are installed with a wrench or a socket. Compared to other fasteners, hex head cap screws provide a larger surface-bearing area for better clamping.
Nickel-based alloys are materials that are composed mainly of nickel and some other alloys. Ni-based alloys are known for their excellent corrosion resistance and strength. They are often found in high-temperature environments due to their superior resistance to heat.
BS EN 4128 specifies the characteristics normal hexagonal head bolts with a coarse tolerance shank and short thread in heat resisting nickel base alloy. This can benefit you as this information is used in various aerospace applications. This can help you increase safety in operations.
