The property courses most often used are 5.8, 8.8, and 10.9. The number before the point is the ultimate tensile power in MPa divided by 100. The number after the purpose is the multiplier ratio of yield power to ultimate tensile energy. Ultimate tensile energy is the tensile stress at which the bolt fails.
The commonest set screw is headless and the drive type is hex socket although slotted drive can also be accessible. Drive hex sockets with a hex key or hex bit. Sq. heads, that are externally wrenched and require enough clearance for wrenching, permit greater set up torque. Alloy steel and austenitic stainless steel (18-8 and 316) are frequent supplies for socket set screws along with brass and nickel-copper (NI-CU) alloy; square heads are available in steel, alloy steel and austenitic stainless steel. Black oxide (thermal or chemical), which presents minimal rust protection, and zinc plating are typical finishes for alloy steel.
