The following common screws may be used during cable installation:

1. Screw thread: Used to fix cable support, casing and other equipment, with excellent fastening performance and bearing capacity. Common threaded screws are threaded hexagonal screws, threaded flat head screws and so on.

2. Self-tapping screws: also known as drilling screws, usually used to fix equipment such as cable brackets and metal frames. Self-tapping screws have the function of self-drilling, convenient installation and disassembly.

3. Pitch screws: mainly used to connect cable bushings to ensure tight connection between bushings to prevent water leakage and loosening.

4. Anchor bolt: used to fix the anchor of the cable bridge and bracket. By installing bolts on the ground, the cable bridge or bracket is fixed reliably.

5. Wood screws: used to fix cable slots, cable slots and other equipment, suitable for wooden substrates.

The selection of the appropriate screws should consider the cable installation environment, the load-bearing requirements of the equipment, and the fixed position. When selecting and using screws, it should be evaluated according to the actual situation, and follow the relevant installation standards and specifications to ensure the firm and reliability of cable installation.
