ForgeFix Hexagon Nut & Nylon Insert ZP

The Forgefix Nyloc hexagon nut is a fastener that incorporates a nylon component to effectively lock the nut into position on the bolt.;The nylon component has a smaller inside diameter than the actual nut. This locks the nut in place by squeezing the nylon firmly around the bolt when tightened. Unlike a standard locking washer, the Nyloc nut prevents the nut from loosening under vibration as the nylon is tightly wedged into the bolt threads and provides resistance to turning when tightened.;The nuts are zinc-plated for increased resistance to corrosion. Their hexagonal shape is designed to be driven by a wrench (spanner) and provides excellent torque when done so.;APPLICATION;Where a permanent fastening is required and loosening must be prevented by movement or vibration.;Can be used on most bolt products including HT Bolts, Carriage Bolts, Threaded Rod etc.;Zinc coatings prevent oxidation of the protected metal to create a longer lasting finish. It does this by forming a barrier and by acting as a sacrificial anode if this barrier is damaged. Zinc oxide is a fine white dust that (in contrast to iron oxide) does not trigger a breakdown of the substrate’s surface integrity as it is formed. The zinc oxide, if left intact, can act as a barrier to further oxidation, in a way similar to the protection afforded to aluminium and stainless steels by their oxide layers.
