Wing Screw

Description:

Wing screws are generally used in construction applications to allow users to make direct adjustments and change calibrations. These screws feature flat projections called the ‘head' on the side of the screws. This provides natural leverage turning and ensures that the pressure on the fingers is evenly distributed and there is no pain while adjusting an instrument. If an application requires frequent access and tightening between each use, then wing screws from ITA Fasteners will get the job done for you.

These screws come in a wide range of sizes to meet all your fastening need. It is also made out of stainless steel, alloy steel and carbon steel materials which ensures that it is corrosion resistant and durable. Another advantage of these screws is the easy installation process which can be followed to set it up. It requires no special assembly and therefore used mostly in consumer products as it can be assembled quickly.
