Products
Name: Nord-Lock washers
Description: Nord-Lock washers secure bolted joints exposed to severe vibration and dynamic loads. They cannot loosen unintentionally, by creating a wedge underneath the bolt head/nut. An ideal solution for bolted joints where failure is not an option.
Details:
Nord-Lock washers
Maintain high clamp load and ensures the function of the joint
Quick and easy to install or remove with standard tools
Locking function not affected by lubrication
Defined and uniform friction conditions for a more accurate preload
Same temperature characteristics as standard bolt / nut
Reusable – will not affect the reusability of fasteners
Hardened to support and distribute great loads
Available with enlarged outer diameter for flanged bolts / nuts
High corrosion resistance
Can be used with fasteners up to grade 12.9
Reliable locking, even for joints with short clamp length
Name: Nord-Lock X-series washers
Description: Nord-Lock X-series have unmatched wedge-locking protection against spontaneous bolt loosening due to vibration and dynamic loads, along with an exclusive spring effect to protect against slackening due to settlement and relaxation.
Details:
Nord-Lock X-series washers
With new technologies and demands, bolted joints increasingly have to withstand stresses from multiple fronts, including vibration, dynamic loads, settlement and relaxation. Yet, no solutions on the market have previously been designed to secure bolts from all of these at once. That has left designers with the difficulty of figuring out which issue — spontaneous bolt loosening or slackening — will have the biggest effect on the joint, and choosing a solution to handle that single problem. Now, there is no need to compromise. Nord-Lock X-series ensures total bolt security while simplifying design and maintenance. There is no need to use and stock multiple solutions. X-series provides bolt security without compromise.
Name: Superbolt multi-jackbolt tensioners
Description: Superbolt multi-jackbolt tensioners are designed to eliminate unsafe and time consuming bolting methods. MJTs replace or retrofit existing nuts and bolts, and only require hand/air tools for installation and removal of any size tensioner.
Details:
A “Superbolt” or “multi-jackbolt tensioner” will spin onto your existing bolt or stud and provide a better way to secure your joint.
If you are tightening a nut greater than 1″ in diameter, the torque you need to tighten conventional nuts and bolts exponentially increases as the size increases. Our products solve this problem and only require hand/air tools to install or remove any size. Eliminate the need for time consuming and unsafe bolting equipment such as sledgehammers, hydraulic wrenches and stud heaters.
Multi-jackbolt tensioners come in a variety of sizes and configurations. Stock items are available for immediate shipment, and we handle custom jobs quickly. If you are experiencing bolting problems such as leakage, thread galling, unsafe working conditions or are using expensive methods to properly bolt your joint, Nord-Lock bolting technologies are the solution for you.

Nord-Lock X-series washers - bolt security without compromise
MALMÖ, SWEDEN — Nord-Lock adds a new dimension of safety to bolt security with the launch of the Nord-Lock X-series washer. X-series combines Nord-Lock’s unmatched wedge-locking protection against spontaneous bolt loosening due to vibration and dynamic loads with an exclusive spring effect to protect against slackening due to settlement and relaxation. This unique combination makes X-series the first, true multifunctional solution — offering the highest security for critical joints, without compromise.
With new technologies and demands, joints increasingly have to withstand stresses from multiple fronts, including vibration, dynamic loads, settlement and relaxation. Yet, no solutions on the market have previously been designed to secure bolts from all of these at once. That has left designers with the difficulty of figuring out which issue — spontaneous bolt loosening or slackening — will have the biggest effect on the joint, and choosing a solution to handle that single problem. Now, there is no need to compromise. Nord-Lock X-series ensures total bolt security while simplifying design and maintenance since there is no need to use and stock multiple solutions.
As with Nord-Lock’s original washers, each washer pair has cams on one side and radial teeth on the opposite side to secure the bolted joint with tension instead of friction. The Nord-Lock X-series washers’ conical shape also creates an elastic reserve in the bolted joint to compensate for the loss of preload and prevent slackening.
