Product Details
RS PRO Black Thermoplastic Knurled Knobs for Self-Assembly
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 for self-assembly, allowing you to turn socket head cap screws into complete thumb screw knobs. Made from Dupont’s high-performance acetal resin, Delrin, these thumb screw knobs benefit from high resistance to creep and fatigue, high toughness, and high tensile strength and stiffness, all while still being a lightweight material.
A socket head cap screw is inserted into the base of the knob by pressing firmly and squarely together. It is advised that a stop or a spacer equivalent to the diameter of the screw head is placed between the screw head and the inside of the knob to avoid over-pressure.
Self-assembly thumb screw knobs: M3 (RS 771651), M4 (RS 771667), M5 (RS 771673), M6 (RS 771689), M6 (RS 771695), M8 (RS 771702).
Features & Benefits
- Acetal thermoplastic resin
- High tensile strength yet light in weight
- Temperature rating -40°C to + 120°C
- Can be paired with socket head cap screws to create thumb screw knobs
Applications
Designed with flexibility in mind, these knurled knobs allow the user to control the length of the knob thread, granting them a vast range of possible applications. The knurled sides provide additional grip for the user, while the low height allows these knobs to be used in space-restricted areas. Possible applications include:
- Fabrication/industrial machinery
- Clamps and fixers
- Storage and general furniture
