Socket Set or "Grub" Screws with a Hex Allen Drive in Metric sizes
Metric socket set screws are available in quality grade A2 Stainless Steel. Stainless steel socket set screws are a type of screw generally used to secure an object within or against another object. The most common examples are securing a pulley or gear to a shaft. Set screws are most often headless, also called blind, meaning that the screw is fully threaded and has no head projecting past the major diameter of the screw thread.
A blind set screw (known in the UK as a grub screw, quite possibly from its figurative resemblance to a soil-dwelling grub) is almost always driven with an internal-wrenching drive, such as a hex socket (Allen) socket The set screw passes through a threaded hole in the outer object and is tightened against the inner object to prevent it from moving relative to the outer object. It exerts compressional or clamping force through the bottom tip that projects through the hole. Metric A2 Stainless Steel is corrosion resistant and rust resistant.
