Nord-Lock Bolt Securing Systems

Nord-Lock offers a premium bolt securing system, which provides safe locking for bolted joints, even when exposed to severe vibration and dynamic loads. Our bolt securing systems give effective security throughout an assembly’s lifetime, resulting in:

  • No bolt loosening caused by vibration and dynamic loads
  • Minimised cost of maintenance, repair and overhaul
  • Significantly reduced risk of lost production or operation due to bolt failure

By allowing Nord-Lock to analyse and optimise your bolted connection you can increase the profitability and productivity of your company and reduce the lifecycle cost of your joints, by avoiding failures, warranty claims and excessive service / maintenance.

High-quality bolt securing systems

Bolt loosening is not a new phenomenon and is always associated with extra costs for the company involved. Regardless of the type of industry, Nord-Lock will solve problems with loosening related to vibrations, dynamic loads and temperature flexing. The secret behind our bolt securing system lies in the geometry – our wedge-locking technique uses tension to make the bolt self-locking. The key is the difference in angles; since the cam angle is larger than the thread pitch, the pair of washers expands more than the corresponding pitch of the thread.

Our experienced local sales engineers help customers solving their bolt related problems on site – usually also providing them with a more cost-efficient solution in the long term.

Our four global technical verification centres have extensive knowledge in bolted joints. With world-class test facilities and software, we help customers to optimise the most demanding types of applications, every day. We have a knowledge database containing thousands of unique tests, performed for our customers in order to provide extensive information about their particular application.

Bolt securing systems for the offshore industry

For many years Nord-Lock has been working closely with a major oil company, to help establish a best practice for bolt securing at heights, and to minimise dropped objects related to bolted joints. The result of that work has put Nord-Lock in several of the world’s largest oil companies’ safety handbooks.

This was only possible thanks to the fact that we meet the high standard that these companies’ set for their suppliers of safety equipment. We also carry a DNV Certificate for our standard range of washers as well as the material most frequently used for corrosive environments, SMO254. The DNV Certificate ranges from 6mm – 36mm in these materials. The DNV Certificate can be downloaded from this page as a white paper.

Online bolt securing product training

While implementing a HSE product in the oil and gas industry, we saw a need for product training. Therefore, we established an e-learning portal for our customers to use. With this convenient online training, the person responsible for mounting the washers will obtain knowledge about how and why Nord-Lock works, and where and when to use it. As long as there is an internet connection, you can take the course from anywhere in the world.

A safety and training manager or equivalent can use the course administration site to define who should take the course, as well as follow the results of the company’s participants. The e-learning site was especially designed for the E&P company, who have a number of different operating sites both on and offshore.

About Nord-Lock

During the last ten years Nord-Lock has grown at a rapid rate. We are trying to be where our customers are, and currently we have sales companies in 16 different countries. We take pride in getting to know every market we operate on well. In other areas, it makes more sense for us to partner up with strong local businesses. We look forward to hearing from you, and learning more about your bolt securing problems.
