GN421-M4-20 Knurled Thumb Screw Black Plastic Zinc Plated

These Thumb Screws are constructed using a Technopolymer (Polyamide PA), which gives superior impact resistance as well as resistance to heat and cold. The Knurled, round shaped head gives extra grip, enabling you to exert more torque to fasten the screw into place. This makes these a strong, robust and durable component. Especially suited for mechanical function components and mechanical engineering, these knobs have many more uses, from cabinet doors to wheel turning these knobs are a great addition or replacement to your old components. The Zinc plated steel Threaded bolt enables you to attach the screw in place for many applications.

Features and Benefit:
• Impact resistant to avoid breakages when accidental collision is made
• -40 °C to 180 °C Temperature resistant so can be used in high temperature machinery or in cold environment areas
• Zinc plated, blue passivated Threaded bolt provides that added anchoring stability and also the option for more fitting applications

Typical Applications:
• Mechanical engineering
• Automotive solutions
