#14 x 3/4" Hex Head Sheet Metal Screws Self Tapping Stainless Steel 18-8

Description: #14 x 3/4" Hex Head Sheet Metal Screws Self Tapping Stainless SteelSheet metal screws have sharp threads that cut into materials such as: Plastic, Plexi Glass, Wood, and sheet metal. 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. Pan heads are slightly rounded with short vertical sides. A Pan head provides a low large diameter head, but with characteristically high outer edge along the outer periphery of the head where driving action is most effective for high tightening torques. 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.About Self tapping ScrewsA 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 materialGeneral Product InformationHead Style : Hex WasherDrive Style : SocketDrive Size : 3/8"Thread : #14Length : 3/4"Material : Stainless Steel 18-8CHOOSE YOUR QUANTITYDetailed Product Information:Head Width Flat to Flat : 3/8"Head Diameter : 0.520"Head Height : 0.240"Thread Diameter : 0.250"Thread Coverage : Full ThreadThread Length : 0.750Point Style : Self-TappingKey Notes:Hex washer head sheet metal screws with a self tapping thread 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 threadThese hex washer head 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 proper drill bit size to use for a pilot hole for this screw is 3/16"These screws have a hex head that can be driven with a nut driver or socket and can be adjusted with a wrench; the built in flanged washer adds a secure grip to the material being fastened into while also preventing the head from crushing thin metalMade 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 hex 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 redPMP brand hex head sheet metal screws are a highly versatile fastener with sharp course threads that pulls together the materials being joined for a secure hold that will last
