The new Nord-Lock combi bolt - for efficient, accurate and cost effective bolt securing
Think of maintenance, repair and operations performed on a radio mast hundreds of metres above ground. While mounting a pair of washers is not a complex task, working in certain settings can make it more difficult and risky than expected. As Nord-Lock products aim to minimise the danger caused by loose parts, dropping a pair of washers is a different story.
and levelling up the reliability of the joining process is more than a key to success. It’s a necessity.” The Nord-Lock combi bolt cleverly combines the convenience

of a combi bolt with the superior locking capacity of Nord-Lock’s proven wedge locking washers. With the Nord-Lock combi bolt customers can rest assured that they will have all bolt parts in the right place regardless of whether they perform maintenance or assemblies up in the sky, deep in the oceans or on any kinds of critical applications.
Improving efficiency, accuracy and cost effectiveness The combi bolt brings numerous advantages to small or
hard to reach applications where it is tricky to mount separate components or where dropping bolt parts can cause serious difficulties and delays. “Having investigated several hundred of bolted joints failures,
I can say that the major part of these failures occurred due to absence of a washer, difficult joining conditions, or inadequate product use. With the Nord-Lock combi bolt we bring our customers a solution that is reliable and cost-efficient”, adds Maxime. If MRO is performed in settings where having a number of
loose parts is problematic and incorrectly mounted or forgotten washers can put all operations in jeopardy, the Nord-Lock combi bolt is an answer.
The Nord-Lock combi bolt is a bolt with an integrated pair of Nord-Lock washers. The washer pair, which has been adapted to this process by diminishing the inner diameter, is assembled onto the bolts blank, and the thread rolling is thereafter performed

Advantages of the Nord-Lock combi bolt The new product offers a solution to customers seeking to
generally rationalise or minimise part count for inventory and logistics. A tightened Nord-Lock combi bolt cannot loosen by itself. With the Nord-Lock combi bolt customers are able to:
• Ensure faster product assembly, thanks to pre-assembled and pre-lubricated parts.
• Decrease failures related to human error; incorrect mounting or neglecting putting on the washers.
• Facilitate product assembly with very small sizes. • Maintain and repair in either difficult surroundings or areas of limited access faster, easier and safer.
• Ensure secured tightening conditions by having the control on both washer and screw.
• Facilitate inventory and logistical savings due to reduced item numbers.
• Make disassembly faster and easier as loose washers can be difficult to remove (especially from counter bore holes).
