Spring Lock Washers DIN127 Type A and Type B

Short Description:

Spring Lock Washers covered in this standard are deemed to be spring washers designed for use with bolt/nut assemblies involving fasteners of property class 5.8 or less, as specified in ISO 898 Part 1. They are intended to counteract the effect of setting which results in bolt/nut assemblies working loose (see DIN 267 Part 26).

► Spring Lock Washers DIN127 Introduction

They do not effectively prevent loosening of the assembly under varying radial load and are thus designed for use with short bolts predominantly subject to thrust.

      Twins-Lock Washers DIN25021

      Twins-Lock Washers DIN25021, also known as Double stack self-locking washers, or Anti-vibration self-locking washers, works by using tension rather than friction, which has been the basis for most traditional fastening methods. This ensures the securing of threaded systems. The part consists of two identical flat washers which have a set of cams on one side and a radial knurling on the other side. A Twins-Lock washer is supplied with a pair of washers glued together to avoid any orientation mistake during assembly. In case of reuse, the washers need to be assembled cams face to cams face.
