The Wing Nut is made of High-strength steel and is typically finished with a Black oxide coating to resist corrosion and rust,. Its threaded M16 design allows it to be easily screwed onto a threaded rod or bolt. The Wing Nut features wings or projections on either side, allowing for easy tightening and loosening by hand without the need for a tool.

With a heavy-duty load-bearing capacity, this type of Wing Nut is suitable for use in applications that require greater strength and load-bearing capacity, such as in the construction of large concrete structures. Its weight of 310 grams makes it more substantial and durable than the light-duty version, providing a secure fastening solution for demanding construction applications.
