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. 5/8" To 6" Lengths in Listing Driver Size: 3/8" Hex, Tensile - 180,000 psi, Hardness - 40 Rockwell C ProductSiteLaunchDate : 2017-07-12T07:00:00.000Z Size : #12 x 5/8" (M5.5x16mm) Style : Socket Shoulder Screw, 6" Long SupplierDeclaredDgHzRegulation : not_applicable UnitCount : 20 UnspscCode : 31161500
