What is BS EN 4136 - Bi-hexagonal head bolts about?
BS EN 4136 is a European standard on aerospace series which covers bolts, normal bi-hexagonal head, coarse tolerance normal shank, long thread, in alloy steel, cadmium plated.
BS EN 4136 specifies the characteristics of bolts, normal bi-hexagonal head, coarse tolerance normal shank, long thread, in alloy steel, cadmium plated.
Who is BS EN 4136 - Bi-hexagonal head bolts for?
BS EN 4136 on bi-hexagonal head bolts is useful for: 
- Manufacturers of aerospace equipment and components
- Bi-hexagonal head bolts manufacturers
Why should you use BS EN 4136 - Bi-hexagonal head bolts?
Hex Bolts are bolt fasteners with six-sided hexagon head and externally threaded body. Hexagonal head profile enables easy wrenching while putting enough torque to the bolting joint. Hex bolts are used with hex nuts or a tapped hole. Hexagon head bolts, Hex machine bolts are other alias of Hex bolts.
Hex bolts can be used in tight spaces to secure wood, metal, plastic, and other materials. Hex bolts are commonly used in buildings, bridges, docks, and highway structures, but you can find hex bolts in all industries and all homes. Cadmium plating is what is known as a sacrificial coating, meaning it corrodes and breaks down before the underlying material, adding a layer of protection to the metal below. Cadmium has several properties that set it apart as a coating material. Those properties include high resistance to saltwater corrosion.
When it comes to the manufacturing and use of aerospace components, reliability and consistent performance are crucial. Hence BS EN 4136 walks you through the characteristics of bolts, normal bi-hexagonal head, coarse tolerance normal shank, long thread, in alloy steel, cadmium plated. This ensures safety and reliability in your organization and in turn increases the efficiency of work.
