En 14399-4 bolts are preloading, high strength structural nut and bolt combinations. Preloaded nut and bolt assemblies frequently exhibit high sensitivity to variations in manufacturing and lubrication. Therefore, it is crucial that the fastener assembly be provided by a single manufacturer who will be in charge of the assembly's proper operation.
The coating of the fastener assembly must be under the control or supervision of the same manufacturer that makes these fasteners in order to ensure a specific, yet consistent delivery of the en 14399-4 hex bolt. In addition to sharing identical mechanical characteristics, the components must also operate equally well or similarly in the assembly. Only if the assembly is tightened according to the right procedure will it be possible to achieve the functional properties of the assembly, which call for a specific set of preload.
Property class 10.9 grade steel was used to build the en 14399 4 bolt standard. In most cases, medium carbon steel alloy, medium carbon steel, or low carbon boron steel are used to make metric bolts of grade 10.9 in the United States. Both quenching and tempering were used to prepare these steel types. The 10.9 grade steel bolts' excellent wear resistance and strong tensile strength are two of their most significant traits. To be more precise, the yield strength and tensile strength of 10.9 grade steel bolts are respectively 1040 MPa and 940 MPa. In applications involving the automobile sector and for other purposes, the en 14399 4 bolt standard is employed specifically for these reasons. The en 14399 4 bolt standard is used in applications involving the automotive industry for precisely these reasons, as well as for bolting large and forged parts.
The EN 14399-4 Bolts have thread diameters ranging from M12 to M36. Suppliers frequently offer these assemblies with either a Hot Dip Galvanized surface treatment or a plain, uncoated surface. The buyer can always get in touch with the supplier about surface finishing or coating depending on the needs of the final application.
