Tassburg Pan Head Self Tappers 4mm x 45 Pack 25

Stainless steel tassburg pan head sheet metal screws will have no problem punching through a thin or light gauge sheet metal but will require a pilot hole for a thicker gauge metal; the tassburg drive has a tendency to slip if there is too much torque applied during installation and these machine screws being made of a high quality stainless steel which is softer than other non-corrosion resistant fasteners are also susceptible to stripping so it is recommended to use a slower speed or to set the clutch on the driver so when the machine screw is fastened completely the drill does not shred the tassburg drive.
