Description:	Wing Bolts, or Wing Screws, featured elongated 'wings' that are designed to be easily operated by hand and are created to DIN 316 AF standard. They can be used with Wing Nuts to create an exceptional fastening that can be adjusted from various positions
Application:	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.
Others:	Wing nuts are used for parts that are frequently disassembled & reassembled, wing nuts offer hand turning in applications where increased torque is not required. A steel wing nut's large metal wings provide for easy hand tightening and loosening, without the need for tools.
