Heico-Scheibe DIN 25201

     DIN 25201 is a standard document that defines the requirements for Heico-lock washers. The Heico-lock washer is a resilient washer with two protrusions on one of its surfaces. These protrusions provide a secure clamping of the nut and prevent it from loosening during operation. Heico-lock is a trademark of the German company Heico Befestigungstechnik GmbH, which specializes in the production of elastic washers and other connecting elements.

Fastening group DIN 25201

     DIN 25201 washers are made of stainless steel and belong to the stainless fastener group.

Materials for the manufacture of DIN 25201 washers

     DIN 25201 washers are made of stainless steel grade A4. The A4 steel grade allows the fasteners to be used at high temperature extremes and in aggressive and humid environments.

Application range of DIN 25201 washers

     According to DIN 25201, the Heico-lock washer must have a special shape and geometry that ensures secure clamping of the nut and prevents it from loosening. In addition, the standard specifies requirements for the size of the washer, the material from which it can be made, and the chemical and mechanical composition of the material.

     The use of Heico-lock washers ensures reliable clamping of the nut and prevents its loosening, which is especially important in conditions of high vibration and load. They are used in the automotive industry, mechanical engineering, shipbuilding and other industries that require a secure connection with the ability to prevent nut loosening.
