Knob housings for screws and nuts

Nut housing M12 (Jet black) Grip screws and nuts>Screw - nut housing

When assembling equipment, it is often useful to be able to grip and turn a fastening element by hand. This requires a suitably shaped grip that works with a screw or nut to allow manual tightening and loosening.

At Plastika Bevc, we have expanded our range with plastic knob housings for screws and nuts. They are designed for assembling hand-operated fasteners, with the housing selected according to the screw or nut and the design of the assembly.

What knob housings for screws and nuts are

Knob housings for screws and nuts are plastic components for assembling hand-operated fasteners. Together with a suitable screw or nut, they form a knob that is easier to grip when tightening or loosening. The shaped outer surface allows the user to hold and turn the fastener by hand.

Where plastic knob housings are used

This type of housing is useful when assembling equipment that requires manual fastening and occasional adjustment. The housing provides the grip, while the screw or nut provides the threaded connection. Both components and their compatibility must therefore be considered when designing the assembly.

Available sizes

The range includes housings for M5, M6, M8, M10 and M12 screws, as well as a housing for an M12 nut. The different sizes allow the housing to be selected to suit the design of the assembly.

When choosing a housing, check its compatibility with the selected screw or nut, its external dimensions and the installation method. The appropriate thread size is the starting point, but the shape of the component fitted inside the housing must also be considered.

When to choose an adjustable clamping lever

If the handle needs to be repositioned after tightening, or if there is limited space for a full turn, consider adjustable clamping levers with threaded studs or adjustable clamping levers with internal threads. These versions allow the handle position to be changed without altering the tightness of the joint.
