Forgefix Pronged T Nuts are a simple and effective product offering bolting capability into various soft substrates They are Zinc Plated for increased resistance to corrosion APPLICATION Used widely in the soft furnishing trades where strong timber connection is required Also extensively used in Playground and Climbing Wall manufacturing GUIDE Use 6mm bolt with M6 and 8mm bolt with M8 T-Nuts When installing the T-Nut tap home and the sharp fins pierce the substrate and fix the T-Nut firmly in place avoiding any rotation when tightening The T-nuts can be used with many bolting products A T-nut also known as a Blind nut is a type of nut used to fasten a wood particle or composite materials work piece leaving a flush surface It has a long thin body and a flange at one end resembling a T in profile The flanges of T-Nuts often have hooks or serrations on the prongs that sink into a wooden work piece providing better retention 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
