Metal To Metal 100mm Wafer Head Self Tapping Screws Stainless Steel Black Oxide
1. Descriptions:
Sheet metal screws are also the go to fasteners for use with plastic wall anchors in drywall.Tapping screws are considered externally threaded fasteners that "tap" their own mating threads in metallic and non-metallic (such as plastic) materials.
Tapping screws, especially Type A, are referred to as "sheet metal screws" because one of their first applications was in ventilation ducts made of sheet metal.They also make excellent fasteners for attaching metal hardware to wood because the fully threaded shank provides good retention in wood Phillips drive is x-shaped for installation with a phillip screw driver.The design is often criticized for its tendency to cam out at lower torque levels than other "cross head" designs.
There has long been a popular belief that this was actually a deliberate feature of the design, for the purpose of assembling aluminum aircraft without over tightening the fasteners.
Stainless steel phillips truss head sheet metal screws will have no problem punching through a thin or light guage sheet metal but will require a pilot hole for a thicker guage metal; the phillips 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 recomended 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 phillips drive
