Sash, Table and Mirror Screws
Brass sash, table and mirror screws.
The sash screw was conceived as a security device for double hung windows. A hole is drilled through one frame and into the other. The flanged nut is set into the second frame so when the screw is inserted and tightened, the two frames are locked together. These screws can be used in many applications where individual sections need to be assembled securely and dissembled easily.
