#4 x 1/4" Sheet Metal Screws Self Tapping Pan Head Stainless Steel Qty 250
Sheet metal screws have sharp threads that cut into a material such as sheet metal, plastic or wood. They also make excellent fasteners for attaching metal hardware to wood because the fully threaded shank provides good retention in wood.
About Self tapping Screws
A self-tapping screw is a screw that can tap its own hole as it is driven into the material.
Some self-tapping screws are also self-drilling, which means that, in addition to the tap-like flute in the leading threads, there is also a preliminary drill-like fluted tip that looks much like the tip of a center drill.
The screws in this auction are not "Self Drilling" and do require a pilot hole for a thick gauge material

Key Notes:
Stainless steel phillips pan 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
Phillips pan head sheet metal screws with a self tapping thread patern that forms its own threads in the material it is being screwed into and is mainly used for attatching two pieces of metal together but also works great in wood and plexiglass because of the coarse thread
Pan heads have a domed top with a flat load bearing surface on the underside that will hold materials being fastened firmly together
Made from stainless steel grade 18-8 which offers a high level of chemical and corrosion resistance that will out perform and out last all zinc plated fasteners for years with out the need to perform costly and time consuming maintenance; 18-8 stainless steel pan head sheet metal screws are a better choice than 410 self drilling screws in out door applications that will be visible because unlike 410 stainless with a high iron content these screws have a low iron content and will not rust or turn red
