Description

Nord-Lock wedge-locking alloy 718 washers with enlarged outer diameter (SP) utilise tension instead of friction in order to secure bolted joints exposed to severe vibration and dynamic loads.

Over the operational life cycle, Nord-Lock washers offer increased operational reliability and lower maintenance costs, while significantly reducing the risks of production stops, accidents and warranty claims.

Nord-Lock wedge-locking washers have been rigorously tested and approved by independent institutes as well as certification authorities.

Advantages
  • Quick and easy to install and remove with hand tools
  • Locking function not affected by lubrication
  • High corrosion resistance
  • Reliable locking, even for joints with short clamp length
  • Reusable, depending on conditions of use

SP Washers
Nord-Lock washers are available in two outer diameters — standard and enlarged. Washers with an enlarged outer diameter (SP washers) are designed to be used together with flanged bolts and nuts (ISO 4161,4162) on oversized and slotted holes, or on sensitive surfaces and soft materials.


Specifications

Metric Bolt Size
M12
Metric Inner Diameter (d)
13
Metric Outer Diameter (D)
25.4
Metric Thickness (T)
3.2
Applications
Applications with high temperatures - gas turbines, turbo charges, incinerators
Material Standard
EN 2.4668 or equivalent
Hardening
Surface hardened
Hardness
≥ 620HV0.05
Hardness Info
In order to assure the unique mechanical locking function of the Nord-Lock washers, the hardness of the mating surfaces must be lower than the hardness of the Nord-Lock washers.
Corrosion Resistance
PREN 29
PREN Info
Corrosion resistance is knows as PREN, or Pitting Resistance Equivalent Number, is a theoretical number calculated from the chemical composition of the raw material. The formula is: %Cr + 3,3x%Mo + 16x%N.
Temperature Range
-160°C to 700°C
Temperature Range Info
Temperature recommendations are based on information from the raw material supplier and testing. The locking function is not affected within the specified range.
Bolt Grades
Up to A4-80
Laser Marking
718
Size Range
M4-M20 available on request, #8 to 3/4" available on request
