Discover more about the Hammer Drive Round Head Fasteners range.

Hammer Drive Round Head Screws are part of Accu's Precision Screws range and they are intended as alternative fasteners to conventional machine screws, and are designed for installation by hammer. Hammer Drive Round Head Screws have a uniquely coarse thread, making them very resistant to rotational loosening forces. These components are intended to create permanent fastenings, and have an advantage over machine screws in that they are not dependent on tightening torque for retention. Hammer Drive Screws are most suitable for use in unthreaded holes, and in unhardened materials such as Stainless Steel, Aluminium, Brass, or Plastics.

Imperial Hammer Drive Round Head Screws

Hammer Drive Round Head Screws are available with diameters ranging from No.00 up to No.14, and lengths ranging from 1/8 inch to 1/2 inch.
