Trim Head Screw
Trim Head Screw

The Trim Head Screw provides a clean finish because of its special head design and is available with painted heads in Black colour. It features a 6-lobe drive, which helps prevent driver-bit cam-out, resulting in easier driving and longer bit life. Type 305 stainless steel is ideal for superior corrosion resistance.
