The main role of flat washers is to increase the size of a screw's bearing surface area, and reduce the surface pressure applied on the fastened object

Curved Spring Washers are commonly used for simple spring applications and exert relatively light thrust loads and are mostly used to lock washers for fasteners or absorb axial end play. The height of the form material can be adapted to any specific load/deflection function that you need.
| Size Range: | M4 - M20 |

These provide axial load to fasteners in case of vibration or thermal expansion, to limit movement. Spring washers are metallic and often preferred to similar springs that cost and weigh more, while taking up more space. They're perfect for applications that require a degree of flexibility.

They can be leveraged to provide maximum load bearing abilities in a small area of operation. The opposing force provided by the conical center can act as a powerful deflection combination to provide the structure with a high friction hold. The washers can be used in series or parallel depending on the applications.

| Hardness & Grades: | Spring Steel (420 ~ 490 HV), SS 304 |
The tooth lock washer is designed to prevent a nut or bolt head from loosening with the strut action set up by the teeth. The teeth, also, absorb shock and vibration. The teeth abrade the grounding surface in electrical grounding applications to improve the electrical connection
| Size Range: | M4 - M30 |

| STD: | DIN 6798A, DIN 6798J & IS 5556 |
| Hardness & Grades: | Spring Steel (350 ~ 425 HV), SS 304, SS 316 |
safety washers are often used as locking elements for safety reasons in secure fastening solutions and anti-vibration. The geometric design is from the shape of bolt and screw, fastening torque and application circumstances. The safety is achieved through friction and mechanical locking effects
