Ball Socket DIN 71805 with Spanner Flats – Type BH2
BH2 is a metal ball socket with an internal thread and spanner flats, used in gas spring assemblies and other mechanical connections requiring angular movement. It can be combined with a compatible ball stud or with one of our brackets with ball studs.
The internal thread connects the socket to a gas spring rod or another threaded component. The spanner flats allow the socket body to be held with a spanner during installation. An internal retaining ring holds the ball stud in the socket. Depending on the variant, an additional safety catch provides further retention. When selecting a socket, check that its mating dimensions are compatible with the ball stud and allow the required movement.
The BH2 range is based on DIN 71805 dimensions. Versions with dimensions that differ from DIN 71805 can also be manufactured to suit specific installation requirements.
BH2 Ball Socket DIN 71805 – Dimensions and Variants
The dimensional table lists the available BH2 product codes, nominal ball diameters, internal thread sizes, installation dimensions and widths across flats. The corresponding technical drawings show the dimensions and construction of each variant.
When selecting a variant, check the nominal ball diameter, internal thread size, installation dimension a and width across flats SW. Dimension a is measured from the ball centre to the threaded end face of the socket. SW indicates the distance between the opposing spanner flats. For use with a bracket with a ball stud, also check the available clearance and required range of movement.
Materials and Available Versions
Standard BH2 ball sockets are manufactured from 11SMnPb30 steel with a white zinc-plated finish. Stainless steel versions are available on request.
We can manufacture ball sockets with dimensions that differ from DIN 71805, alternative materials and different coatings or surface finishes to meet customer requirements. Versions with fine-pitch or left-hand threads can also be evaluated for the intended application. Please specify the required dimensions, material and surface finish when requesting a custom ball socket.
