At JM Hardware®, we are a leading DIN 25201 wedge lock washer manufacturer, providing high-performance washers engineered to ensure secure fastening even in the most demanding environments. Designed to resist loosening caused by vibration or dynamic loads, these washers are essential for industries where safety, reliability, and precision are critical. With advanced manufacturing capabilities and strict quality control, we deliver DIN 25201 wedge lock washers that exceed industry standards and customer expectations.
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.
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
