Alloy Steel Set Screw, Hex Socket Drive, Knurled Cup Point, M4-0.7, 25mm Length (Pack of 25)
Set Screws are often used for holding a pulley, gear, or other parts from turning relative to a shaft. Alloy Steel is steel that has been alloyed with other materials to improve overall physical properties. Steels are designated by a 4 number SAE Steel grade. The first two digits indicate the primary materials used to form the steel. The last 2 digits identify the percentage of carbon for the alloy (in hundredths). Tensile strength ranges for the alloys typically used in these fasteners range from 170,000 to 180,000 psi (pounds per square inch), making these amongst the strongest of materials. Hex socket drive systems are driven by hex wrenches or power tools with hexagonal bits. Also known as oval cup, the round tip of the Knurled Cup Point minimizes deformation of the contact surface, and is ideal for applications requiring frequent adjustments. A threaded fastener’s size name includes information about the major external diameter (in millimeters), followed by the thread pitch (millimeters per thread), which indicates if it is coarse or fine. Coarse threads are better when working with brittle materials; they are sturdier and are easier to thread and unthread compared to fine. Coarse threading also allows for thicker coatings and platings. Get ¡t riɡht aωaУ!n! I l0vе ìt!
