Philips Cross Recessed Carbon Steel Csk Head Self Drilling Tek Screw

Philips Cross Recessed Carbon Steel  Csk Head Self Drilling Tek ScrewProduct DescriptionSelf-drilling screw is a screw that can tap its own hole as it is driven into the material. For hard substrates such as metal or hard plastics, the self-drilling ability is often created by cutting a gap in the continuity of the thread on the screw, generating a flute and cutting edge similar to those on a tap. Thus, whereas a regular machine screw cannot tap its own hole in a metal substrate, a self-drilling one can (within reasonable limits of substrate hardness and depth). Product NameFactory Direct High Strength White Zinc Flat Head Cross Tapping Screw Carbon Steel Self Drilling Screw   materialStainless Steel,Carbon Steel,C1022aSurface TreatmentWhite blue zinc platedHead TypeCountersunk head,Flat headDiameterM3.9,M4.2,M4.8Length13-100mm Detailed Photos Product ParametersSize(inch)Size(mm)Size(inch)Size(mm)Size(inch)Size(mm)#7x1/2''M3.9x13#8x1/2''M4.2x13#10x1/2''M4.8x13#7x5/8''M3.9x16#8x5/8''M4.2x16#10x5/8''M4.8x16#7x3/4''M3.9x19#8x3/4''M4.2x19#10x3/4''M4.8x19#7x1''M3.9x25#8x1''M4.2x25#10x1''M4.8x25#7x1-1/4''M3.9x32#8x1-1/4''M4.2x32#10x1-1/4''M4.8x32#7x1-1/2''M3.9x38#8x1-1/2''M4.2x38#10x1-1/2''M4.8x38#7x2''M3.9x50#8x2''M4.2x50#10x2''M4.8x50#7x2-1/2''M3.9x63#8x2-1/2''M4.2x63#10x2-1/2''M4.8x63#7x3''M3.9x75#8x3''M4.2x75#10x3''M4.8x75     #8x3-1/5''M4.2x80#10x3-1/5''M4.8x80     #8x3-1/2''M4.2x90#10x3-1/2''M4.8x90     #8x4''M4.2x100#10x4''M4.8x100Packaging & ShippingCompany ProfileTianjin Boya Metal Products Co.,Ltd was began from 2001.Our main products are common nail, jolthead nail, duplex head nail ,concrete nail,U fence staples ,cut masonry nail,roofing nail,clout nail and all kinds of nails,black annealed wire, twisted wire,electrical galvanized wire ,hot dipped galvanized wire wires and wire mesh products used in construction and decoration.
