Product Description

    Nord-Lock Washers For Nuts - DIN 25201

 QBH Nord-Lock Washers prevent nuts and bolts from becoming loose because of vibration or dynamic load. They have a wedge-locking action which uses tension rather than friction. They can only be used in conjunction with a conventional bolt. The rise of the cams between the Nord-Lock Locking Washers is greater than the pitch of the bolt. In addition, there are radial teeth on the opposite side.

    The locking washers are supplied and installed in pairs - cam face to cam face. When the bolt/nut is tightened, the teeth grip and seat onto the mating surfaces. The washers lock in place, allowing movement only across the face of the cams. Any tendency for the bolt/nut to loosen is blocked by the wedge effect of the cams. This positively locks the fastener even when it is subjected to vibration or dynamic loads.

     QBH  Nord-Lock Locking Washers have a high corrosion resistance and can be reused up to 5 times.
They are available in in thread sizes from M3 to M42 and diameters from 7mm to 63mm and they meet the DIN25201 standard.

Advantages:
• Resist loosening caused by vibration or movement
• Ease of assembly and disassembly
• Locking function is not lost by lubrication
• Positive locking at low and high preload levels
• Same temperature characteristics as standard bolt/nut
• Reusable up to 5 times

Typical applications:

 

Construction equipment, Automotive and Trucking industry, Agricultural equipment, Utilities, Manufacturing Equipment, Railroad equipment, Process industries

Material - Available in Steel and Stainless Steel
