Knurled Knobs and Hexagonal Screws

Knurled knobs screws are used wherever connections are frequently loosened and no tools are needed for operation. These connecting elements are available in various designs, made of different materials and both as knurled screw with an external thread and in the design of the nut with a blind hole or through thread and in numerous sizes. Basically, this component is divided into two forms, a high form which has a longer head and a flatter form.

Knurled screws and handles are characterized by the large knob, which is knurled on the edge, thus improving the ease of use. An unintentional slipping is avoided. To prevent the screw from loosening by itself, the connection to the workpiece is secured by a metric thread.

BÄCKER offers knurled handles in different shapes, sizes and specific material designs. Stainless steel versions are corrosion protected and can also be used for outdoor applications, whereas versions with a galvanized thread allow higher tightening torques. Basically these are classified according to two criteria:

Knurled thumb screws in high design

are characterized by a connecting piece which creates a distance between the knurling head and the workpiece and thus prevents the knurling head from making contact.

Knurled head screws with low profile

This design is characterized by a continuous thread up to the knurled knob. The shape is chosen extra flat, thus requiring less space for operation and lies directly with the head against the workpiece.

A special form of the knurled screw is the version with a slot in the knurled knob, which allows both adjustment without a screwdriver and adjustment with a screwdriver. This allows greater flexibility for the user.
Knurled knobs are used in many different ways

Due to the uncomplicated, tool-free operation, the variability of size, material and shape, knurled screws and handles can be used universally where adjustments can be made without much additional effort. Frequent fields of application are the adjustment or adjustment of the size of two elements running into each other, e.g. telescopic extension, where the knurled screw fixes the desired position. Knurled handles are used as a connecting element or as a cover for mechanical components where operation must be carried out quickly without additional effort, e.g. maintenance flaps on machines or even household. appliances).
