Disc and Conical Spring Washers
These are used for locking a device and reducing the vibration. They reduce loosening by preventing unscrewing rotation of the fastening device; locking washers are usually also spring washers.
Washers are available in a wide range such as spring washers, star washers, multi-tooth washers, disc spring washers, wave washers, taper washers, safety washers etc.
Conical Spring Washers
DIN 6796
A Conical spring washer designed to help prevent loosening of bolted joints under vibration. This type, manufactured to DIN 6796 has an inherent conical shape. It is also known as a Belleville washer, disc spring, coned-disc spring and cupped disc washer.

Plain Washers
A plain washer is a thin plate, which is most commonly has a disk-shape with a hole in middle. It is widely used to distribute the load of a threaded fastener. Plain washers are used to provide a larger bearing surface where screws, bolts and nuts come in contact with the bearing surfaces.
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.
Looseness can result when the bearing surface sinks under the surface pressure, so using a flat washer to reduce the surface pressure is very effective.This is especially crucial if the contact area between a screw’s bearing surface and the object being fastened is small when fastening to a slot, for instance, or if the object being fastened is made of soft material such as aluminum or resin.

Retaining Washers
Retaining Washers feature internal fins, which grip the thread of a fasteners, creating a self-retaining fastening. Retaining Washers are designed for use with Captive. The combination of Captive Screw and Retaining Washer creates a lightweight and cost-effective locking solution for safety applications.
A Plastic Retaining Washer is primarily used to hold screws and bolts in place during assembly and have a design that grips the outside of screw or bolt shank. Also known as an Anti Loss Washer, they provide insulation, cushioning and spacing. They help insulate fastening assemblies from moisture and electricity.
This washer range includes options with internal and external teeth with a tapered design. The washer slides/assembles on to the screw (or bolt) and is retained by the screw once assembled. The washer cold forms and fully enters the pitch of the screw to provide sealing.
These washers allow for preliminary mounting of the screw (or bolt) before securing with a nut. They are ideal when pre-assembly of the screw and washer is required.

Safety & Conical Spring Washers
These are used for locking a device and reducing the vibration. They reduce loosening by preventing unscrewing rotation of the fastening device; locking washers are usually also spring washers.
Washers are available in a wide range such as spring washers, star washers, multi-tooth washers, disc spring washers, wave washers, taper washers, safety washers etc.
Serrated Safety Washers Type S – Schnorr Type
The Safety Washers are of trapezoidal cross section and serrated on both sides. The security is achieved through friction and mechanical locking.Advantages- The cross section ensures locking effect at the outside diameter.
- Due to the closed ring form, high degree of pretensioning is achieved.
- Sliding surfaces allow tightening with damaging the mating surfaces.
- High resistance to vibration due to positive locking of the serrations
- Suitable for a wide range of screw/bolt heads minimizing stocks.

Spring Washers
These are used for locking a device and reducing the vibration. They reduce loosening by preventing unscrewing rotation of the fastening device; locking washers are usually also spring washers.
Washers are available in a wide range such as spring washers, star washers, multi-tooth washers, disc spring washers, wave washers, taper washers, safety washers etc.
Spring Washers Type A Square
DIN 7980
A Spring washer is a metal ring split at one point and bent into a helical shape. This helps the washer to exert a spring force between the fastener’s head and the surface. This keeps the washer firm against the substrate and the bolt thread hard against the nut or substrate thread, creating more friction and resistance to rotation.
A spring washer square has square ends at the split end. Provides much better resistance as compared to a plain washer.
Size Range – M3 to M48
Materials – Spring Steel, Stainless Steel AISI 301 and 316. Titanium on request.

Star and Tooth Washers
The main purpose of toothed lock washers is to permit the flow of electric current between components coated by varnish, anti-corrosive agents or similar materials. The bent ends of the washers piercing the coating when such components are joined. For such applications, the effectiveness of toothed lock washers shall be verified in accordance with the relevant DIN VDE Standards.
These are also used for locking a device and reducing the vibration. They reduce loosening by preventing unscrewing rotation of the fastening device; locking washers are usually also spring washers.
Washers are available in a wide range such as spring washers, star washers, multi-tooth washers, disc spring washers, wave washers, taper washers, safety washers etc.
Star Washers Internal Type
DIN 6797J
These are locking washers that form part of the serrated or toothed type of washers. They feature serrations or teeth that extend radially inward to bite into the bearing surface.
Their effectiveness is more evident on soft substrates such as plastics or Aluminium although they do resist rotation better than plain washers on harder surfaces. As per DIN 6797J
Available in stainless steel AISI 304 and AISI 316.
