The Greenlee Communications 3691GB is a set screw with a socket drive, specifically designed for mechanical fastening applications. The component features a 1/4-20 thread pitch and a length of 0.375 inches. It is classified as an unclassified hardware item within the manufacturer's portfolio. The product is currently in active production status and is available through standard distribution channels.
Verify the exact thread specification (1/4-20) and length (0.375 inches) against your design requirements before ordering. Confirm that the socket drive type matches your available tools. Ensure compatibility with the mating material and torque specifications for the intended application to prevent failure.
Select this part when a compact, socket-head set screw is required for securing components without protruding heads. The 1/4-20 thread size is common in industrial machinery. Consider the material grade and surface finish if corrosion resistance or specific strength properties are critical for the operating environment.
Greenlee Communications provides a range of tools and hardware for communication infrastructure. This specific item falls under general hardware rather than specialized test equipment. It supports the installation and maintenance tasks associated with datacom and telecom physical layer deployments.
Substitute parts must match the 1/4-20 thread pitch and 0.375 inch length exactly. Socket head cap screws from other manufacturers may be used if they meet these dimensional standards and possess equivalent mechanical strength ratings.

Choose a DIP switch by contact type, coded positions, footprint and signal ratings. Check logic polarity, assembly conditions and PCB configuration behavior.
