HV bolts EN 14399-4 for preloaded connections

An HV bolt works as part of a specified bolting assembly. Thread diameter and property class 10.9 alone are insufficient to replace it with an ordinary structural bolt. Selection should consider connection documentation, system designation, surface finish and assembly manufacturer requirements.

How do you select diameter, length and clamping range?

Thread diameter: should match the connection design and mating nut.
Screw length: is selected for joined-part thickness and washer arrangement, taking the assembly clamping range into account.
Class and markings: check bolt markings and documents identifying the HV assembly.
Coating: hot-dip galvanising requires compatible assembly components. Do not arbitrarily combine parts with different surface designs.

DIN 6914 and EN 14399-4

DIN 6914 appears in the subcategory name and is used when searching for HV bolts. However, it does not replace confirmation that the specific product and complete assembly meet project requirements. When ordering, follow the product page, manufacturer documentation and identification of the supplied batch.

Selecting and installing an HV assembly

Match the bolt with compatible nuts EN 14399-4 and washers EN 14399-6. Keep the components assigned to their assembly and manufacturer. Tightening parameters follow from installation documentation and the properties of the specific assembly. Additional lubrication can change friction conditions and must not be introduced independently.

Frequently asked questions about HV bolts

Is every 10.9 bolt suitable for preloading?

No. Property class does not confirm membership of the HV system or suitability of the complete assembly for a particular preloading method.

What information should be prepared for an enquiry?

State diameter, required length or clamped stack thickness, standard, coating, number of assemblies and required documents. This makes an enquiry to NERON in Piła more precise. Also see the category preloaded HV connections EN 14399.
