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.

In addition, Washers are also used for locking a device and reducing the vibration. These locking washers are available in various types such as spring washers, star washers, multi-tooth washers, disc spring washers, wave washers, taper washers, safety washers etc.

 

These are available in Mild Steel, Spring Steel and Stainless Steel.

For use under Machine Screws, smaller OD washers are preferred. These are made as per DIN 433.
Available in SS-304 and SS-316

We offer a comprehensive range of E type circlips.

The most common form of radially fitted circlips for shafts with grooves. Provide a large shoulder on a relatively small shaft diameter. This range can be supplied stacked on rods for use with applicators and dispensers for rapid installation, thus resulting in sharply reduced assembly costs.

Only the groove size is critical with this type of circlip, the shaft diameter can be varied widely.

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.

Special dimensions are available under our Penny Washer Series.

These have a larger outer diameter and are suitable for softer materials.

 

These are available in AISI 304 and AISI 316.

Bolted connections tend to work themselves loose under certain operating conditions. Vibrations cause particular problems as they can overpower the “self-locking effect” of bolted connections. This can lead to functional failure or even to the connection coming apart. As it’s not always possible to know what forces are acting on the structure, and as constructional measures cannot be implemented everywhere, securing elements are often used.
One of the few effective securing technologies available is the HEICO-LOCK® wedge locking system, the effectiveness of which has been demonstrated by the latest experimental standards (including DIN 65151, DIN 25201-4, NASM 1312-7).
FUNCTIONAL PRINCIPLE
An important feature of HEICO-LOCK® wedge lock washers, setting them apart from other systems that are available, is the securing of the bolt fastening using preload force rather than friction
Wedge-shaped cams on the inside of the lock washers, radial teeth on the outside
Interlocking embedding of the radial teeth with the respective mating surface   (when tightening the bolted joint)
System movement only possible between the inner wedge shaped cams.   Movement across these wedge shaped surfaces effectively self locks the bolt.
Increase in clamping force.

Certified system for securing bolts, working at low and high preload levels.
Particularly suitable for dynamic loads – including when using lubricants.
Can be re-used.
Very easy to install and remove (wedge lock washers are supplied   as a pre-assembled pair)
Also suitable for high-tensile bolts of 8.8, 10.9 and 12.9 and their respective nuts.
Available in steel or stainless steel with narrow or wide bearing surfaces – other materials are available upon request.
Available from M3 – M76 and ¼” – 3” - custom sizes upon request.

Shim rings are flat washers used in combination when axial clearance must be offset. This could be on a shaft where there is a locking ring/bearing, between which clearance must be offset. By combining washers of different thicknesses you can precisely offset the clearance.
Shims refer to a broad class of specialty flat washers that are used for positioning and spacing. While shims look like flat washers they are different in that shims are typically made  using more precise materials and production techniques.
Axial play resulting from manufacturing tolerances can be rigidly reduced by using various thicknesses of shim washers.

Applications:

• Compensation for axial play
• Mechanical engineering
• Automotive engineering
• Gear systems
