== Selection criteria of the screw for satellite ==
Screws are used to attach any two surfaces in contact on our satellite. The size of the screw will be decided by the maximum depth of penetration of the hole. The screws are generally made of the material SS304 (stainless steel). <br \>
Single slotted and Phillip Phillips screws tend to slip off while using a screwdriver to screw them.These fasteners are easily damaged at the slot. In addition, these are hard to use with a torque wrench. <br \>
Allen/hex head fasteners are very common in most equipment. These are more durable and less likely to slip. This also allows use of torque wrenches. Hence, allen headed screws are a good alternatives.
