Webb27 mars 2024 · This screw is the one used to hold the fans to the case of our computer. Its head is flat, with a conical shape to enter the flare and is usually of the Philips No. 2 (star) type. The diameter of the thread is 5.5 mm and its length, excluding the head, is 10 mm. As a rule, computer case manufacturers usually include up to 4 of these screws. WebbRundown Torque Limits; Rundown Torque Limits. The friction between the screw and joint varies. This can cause the torque needed to run a screw down a thread, before engagement with the joint surface takes place, to vary as well. These effects could be, for example, hole interference, prevailing torque or varying lubrication.
