M5 Nyloc Nuts Zinc Plated

• A nyloc hexagon nut is a fastener that incorporates a nylon component to effectively lock the nut into position on the bolt.
• Type P are slightly taller than the type T version.
• 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.

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 substrates 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 aluminum and stainless steels by their oxide layers.
