The split lock washer will compress while pushing back against the adjoining surface to prevent loosening from vibration. Curved Split Lock washers have a wave 

With an increased O.D., thickness and bearing area, this split washer is ideal for heavier duty applications involving the application of higher tightening torques. The Heavy Section helical spring lock washer contributes significantly to the maintenance of tightness or tension in applications involving screws, bolts and nuts under high loads.

The lockwasher serves as a spring while the bolt is being tightened. However, the washer is normally flat by the time the bolt is fully torqued. At this time it is equivalent to a solid flat washer, and its locking ability is nonexistent. In summary, a lockwasher of this type is useless for locking." (p9)

A helical lock washer (also called a "split washer") looks like a ring with uneven ends. The ends of the ring bite into fastener material to 

Helical spring lock washer delivers even load distribution on bearing surfaces. Most people who have used this spring lock washer on assembly components like its effectiveness. How does helical spring lock washer work? It contains a split section which is designed to absorb the driving torque. The reduction of tension causes bolt loosening.

Helical spring lock washers have been historically among the most widely used anti-loosening assembly components on the market. · They enhance the security of 

They are also often called split lock or split ring washers. A spring washer has a split in the washer section that when tightened each side of the split 

Metric DIN 127 Helical Spring Split Lock Washers are commonly used metric lock washers - It is a split metal ring that is bent into a helical shape. Split Lock Washers are a left hand helix and allow the nut to be tightened in a right hand direction only. When compressed by tightening the nut, the washer bites into the substrate and exerts a

Helical Spring‐Lock Washer as follows: “2.1 The helical spring‐lock washers covered in this Standard are intended for general applications. Helical spring‐lock washers compensate for

Split Lock Washers, which are also called helical spring lock washers, are metal rings split and twisted so the cut ends no longer align. When compressed, they are squashed flat and exert force to regain their original shape. In addition to acting as a spring, a split washer may penetrate the surface of softer metals, increasing friction that

The tension generated by the deflection of a helical spring split lock washer meets the needs of most commercial applications. Split lock washers also reduce scratching on the assembly surface which may be a problem with a toothed lock washer. Our lock washers meet all ASME standards in addition to RoHS and DFARS compliance when required.

Optimum locking device for use in applications with hardened faying or bearing surfaces. The "Split" in the helical spring lock washer absorbs initial driving torque and visually closes under nominal bolt loading. When tension in the assembly is reduced and loosening occurs, it pro- vides resistance to the back-off rotation of the screw.
