These Forgefix Wing Nuts are a convenient alternative to the standard Hex Nut and allow hand tightening rather than having to use spanners or other tools The nuts are bright zinc plated for increased corrosion resistance Also known as a Thumbscrew the wing nut has two large metal wings for easy tightening and loosening APPLICATION Where ever a hand tightened fastening is required Used where frequent adjustments are needed or part removal can be made quickly at some later stage Can be used with all threaded bolt products 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 aluminum and stainless steels by their oxide layers
