Product Details
RS PRO Black Polymer Push/Pull Knurled Knobs
Knobs are used in a wide variety of applications in our day-to-day lives and perform many functions, from being used as fixed handles to being used to tighten, loosen, adjust, clamp and push other components or pieces of equipment. They are used in various applications, from industrial and construction machinery to audio and visual equipment.
From RS PRO comes these knurled knobs made of shatterproof polymer thermoplastic with either a brass female insert or a zinc-plated steel male stud. Designed to be used for push/pull applications rather than clamping, fixing or tightening, these knobs have a concave recess for the user’s comfort when applying pressure to push or pull the application.
The low height of the knob allows for this style of knob to be used in space-restricted areas, and the knurled edge enhances user grip. The increased space between the head and the shank of the knob allows for comfortable use, even when the user is wearing gloves.
