The length of the drill point determines the material thickness which the screw can reliably penetrate. When selecting a self-drilling screw design, it is important to consider the material thickness and type of materials to be joined. These stainless teks are great to use in environments that are damp. 1/2" To 2-1/2" Lengths in Listing Driver Size: 5/16" Hex Tensile - 180,000 psi, Hardness - 40 Rockwell C ProductSiteLaunchDate : 2016-12-01T08:00:00.000Z Size : #10 x 5/8 Inch Style : Pro Self Drilling Screw Square Drive Trim Head, 1 5/8" Long SupplierDeclaredDgHzRegulation : not_applicable UnitCount : 10 UnspscCode : 31161500
