Can Nord-Lock washers be reused?

Nord-Lock washers can normally be reused. As with all fasteners, they should be inspected for wear before reassembly. Make sure that the washers are reinstalled correctly cam face to cam face. Nord-Lock recommends lubrication of fasteners before reuse in order to minimize changes in friction conditions.

Do Nord-Lock washers work?

Nord-Lock washers secure bolts with tension instead of friction. The system cannot loosen unintentionally as it creates a wedge-effect underneath the bolt head or nut. When the bolt is tightened, the teeth grip and seat the mating surfaces.

What is the best lock washer for vibration?

We found that the most effective anti-vibration solutions are anaerobic adhesives and mechanical washers. Overall, Nordlock washers were extremely effective. They’re as easy to install as any standard washer—and easier to install than the next-best contender, the Loctite 2760 adhesive.

What is North lock?

Nord-Lock wedge-locking technology secures bolted joints exposed to severe vibration and dynamic loads Superbolt technology eliminates unsafe and time-consuming bolting methods Boltight tensioning tools provide fast, accurate and safe tightening of multiple bolts simultaneously The Expander System provides a simple and …

When should you not use a Nord-lock washer?

Designs where Nord-Lock SC-washers are not recommended:

• With plain washers.
• When mating surfaces are not locked in place.
• When mating surfaces are harder than the washers.
• With very soft mating surfaces — for example, wood and plastic.
• For applications with extremely large settlements.

What are Nord-lock washers used for?

Nord-Lock washers safely lock the nut on stud bolts and eliminate the need for adhesives. To optimize the load distribution for applications with large / slotted holes or with soft underlying surface, use a flanged nut / bolt together with Nord-Lock “SP” washers with enlarged outer diameter.

What are Nord-Lock washers used for?

Do you need a lock washer with a lock nut?

Lock nuts typically have a malleable insert that deforms to grip the threads of the bolts they’re threaded on to, which in turn keep the nuts from vibrating loose. Most projects will call for either locking washers or locking nuts — not both — to be used on a given fastener.

Should you use a lock washer with a lock nut?

Locking Washers Place the lock washer between the nut and the work surface if using a nut-and-bolt configuration, or between the fastener head and the work surface if using a tapped hole configuration. In other words, the bolt goes straight into the hole and doesn’t poke out the other end, so no nut is used.

When should you use a lock nut?

Locking nuts should be used when the screw joint consists of one or more soft materials. It is difficult to achieve and to maintain a high level of clamp load because the soft material deforms due to high surface pressure. This plastic deformation continues after the torque value has been applied to the screw.

What does a lock nut do?

Lock nuts with nylon inserts (self‑locking nut, locking nut) are a prevailing torque, locking nut that resists loosening caused by vibration and normal use. Unlike free spinning nuts, lock nuts make use of a deforming elastic or metal material to stay in position against torque and shock.

What can a Nord lock washer be used for?

Read more Nord-Lock Group keeps the railway industry on track Nord-Lock wedge-locking washers are used in all safety-related areas of the railway industry, such as bogies, coupling devices, brake systems, rail dampers. Read more

Which is better Nord lock or Split Tooth washer?

Also known as NORD-LOCK® washers, these two-piece washers provide more locking power than split, tooth, and spring lock washers. Wedges on the inside lock the two pieces together, and serrations on the exterior grip surfaces to resist loosening from high vibration and shifting.

How does torquelator work on Nord lock washers?

Torquelator by Nord-Lock calculates the preload and corresponding torque for bolted joints secured with Nord-Lock washers. Makes installation easier! Torquelator by Nord-Lock calculates the preload and corresponding torque for bolted joints secured with Nord-Lock washers. Makes installation easier!

Is it possible for a Nord lock nut to loosen?

It is impossible for our products to loosen unintentionally due to the wedge created underneath the bolt head and nut. This product can expose you to chemicals including Nickel and Mineral Oil, which are known to the State of California to cause cancer.
