Hex Standard Full Nuts are the most common nuts available and are used with machine screws bolts threaded rods and on any other fastener that has external screw threads. Hex is short for hexagon which means they have six sides Benefits of Nylon: Provides good toughness tensile strength non-conductive and resistance to creep particularly in the high temperature range Excellent wear properties low coefficient of friction and exceptional chemical resistance to aromatic hydrocarbons greases and oils Nylon is a hygroscopic material which tends to absorb water or moisture from the surrounding environment. The amount of absorption will depend on the environmental conditions. When water or moisture is absorbed by Nylon it behaves like a plasticizer in plastics reducing the tensile strength stiffness; and increasing elongation impact strength and energy absorbing characteristics Nylon will perform well in long range service in most applications Material / Coating: Nylon PA PA6.6 66 is the standard polymer used in the Hobson range of fasteners and is recognised worldwide for being the most suitable material for fasteners Thread Pitch (Metric): is the distance between the peaks of two threads along a screw bolt nut or fastener expressed in millimetres (mm).
