These ForgeFix traditional slotted round head Wood Screws have a Black Japanned finish, and are used in many decorative and ironmongery applications. APPLICATION: Used for fastening many ironmongery products such as Tee-Hinges and Antique furniture. Japanned is most often a heavy black lacquer, almost like an enamel paint. Ironware is often Japanned black for decorative purposes. It can also be used to render fixings rust-proof. With Slotted screwdrivers it is important to ensure that the tip matches the width of the screw slot, otherwise you run the risk of damaging the screw head. Slotted screwdrivers are available with either Flared or Parallel tips. For the majority of uses the Flared tip is ideal but if the screw needs to be driven below the material surface a Parallel tip screwdriver should be used. Round head screws have a flat under head surface making the screw ideal for laying flat on sheet material of all types, reducing deformation. The screws have single threads, which have been designed to offer higher pull out values and quicker insertion. Wood Screw Slotted Round Head ST Black Japanned 3/4 x 8in Forge Pack 25 FORFPR348J
