EJOT\u00ae SUPER-SAPHIR JT6 self-drilling screws are made from Marine Grade 316 Stainless Steel Bi-Metal<\/a>. They feature a screw head and threads that are made of 316 stainless steel, providing exceptional corrosion protection and superior ductility<\/strong>. SUPER-SAPHIR JT6 self-drilling screws have a classic\u00a0drill point and are designed to drill, form the thread and fasten components in one work step<\/em>.\u00a0The drill point is made of hardened carbon steel that is welded to the body. This allows JT6 fasteners to drill and tap steel up to 1\/2 thick<\/strong>.\u00a0\u00a0EJOT\u00ae SUPER-SAPHIR JT6 self-drilling screws\u00a0are completed by an optional pre-assembled sealing washer.<\/p>\n <\/p>\n <\/a><\/p>\n To properly select your SUPER-SAPHIR JT6 Self-Drilling Screws<\/a>, you must take into account the clamping thickness and required drilling performance. To calculate the clamp thickness, you take the thickness of the attachment (a) PLUS (+) the strength of the substructure.<\/p>\n The following formula can be used: Clamp Thickness\u00a0Greater than or Equal to (a) + 6mm.<\/strong><\/p>\n The drilling performance is calculated from the thickness of the components to be drilled.<\/p>\n The following formula can be used for Direct Bearing Surface (trapezoidal profile to steel substructure): t = component (tI) + component (tII).<\/strong><\/p>\n The following formula can be used for Sandwich Panels: t = component (tII).<\/strong><\/p>\nEJOT\u00ae<\/sup> SUPER-SAPHIR Self-Drilling Screws Features<\/h3>\n
