Metric Economy Grade Thumb Screws â€“ Compatibility & Materials Used
Metric economy grade thumb screws are designed to be compatible with other hardware and appliances manufactured using the metric system. They are used in a variety of industrial and other commercial applications. Thumb screws are used to join layers of wood and other thin materials together. The force of a hand or thumb is enough to drive these thumbscrews into the designated space. They are named â€˜thumbscrewsâ€™ because a thumb is used to install them. For better grip, they feature ridges on the side of the screw where the thumb and fingers make contact with the screw. In recent times, they also have slotted heads to be used with screw drivers.
Importance of â€˜Metricâ€™ in Metric Economy Grade Thumb Screws
The metric system of measurement is used to manufacture these screws. This means that the dimensions and other technical specifications are in accordance with the metric system. This makes them compatible with most instruments and hardware available in countries using the metric system. Integration of metric thumb screws is easier. This expands the product range to a big extent making these thumb screws widely used across several industries.
Materials Used to Manufacture Metric Economy Grade Thumb Screws
Generally, the materials used to manufacture metric economy grade thumb screws are low-cost. Hence, variants of the expensive materials are available to make them affordable and usable. The following materials are preferred in most applications:
- Carbon and glass-filled PEEK
- TEFLON (PTFE)
- ECTFE (Ethylene chlorotrifluoroethylene)
- Polycarbonate and several more
Metric economy grade thumb screws are extremely useful in securing and clamping functions. They feature a variety of thread sizes making them compatible with various materials, applications, and industries.
