50pcs M11 Type Screw Repair Inserts - Stainless Steel Threaded Sleeve Assortment for Strong Connections(M11x1.5x3D)

50pcs M11*1.25/M11*1.5 helicoiI Type Screw Repair Sleeve Inserts Screws Sleeve Assortment Stainless Steel Fastener AccessorySpecifications:Material: Stainless steel 304Size: M11(Inner Diameter) x 1.25/1.5(Installed Pitch) x 1D/1.5D/2D/2.5D/3D(Installed Length)Outer Diameter: 14.40mm(Min.); 14.80mm(Max.)Suitable Drill Bit Diameter: 12.3mmQuantity: 50pcsPackage Includes:50pcs x Threaded InsertsTipsThe following table includes the length of L1 that we measured manually. Due to the irregular shape and elasticity of the wire thread insert, the measurement results will be different due to the different angles and positions of the measurement.For example, In factM6*1.0*2D 6mm*2=12mmM6*1.0*3D 6mm*3=18mmM6*1.0*2DM6*1.0,indicates that the internal thread after installation is M6*1.02D, indicating that the minimum depth of the mounting hole is 2D=6mm*2=12mmAfter drilling, you need to use tap ST6*1.0 to process the thread. Because the tap has a taper, the thread in the hole is less than 12mm, so the actual length of the wire thread insert before or after installation are both less than 12mmThe actual length of the wire thread insert after installation = the number of turns of the wire thread insert W * the pitch PThe actual length of M6*1.0*2D after installation is about 9.6*1.0=9.6mmM8*1.25*2DMinimum depth of the mounting hole is 2D=8mm*2=16mmthe number of turns of the wire thread insert W=10.6, the pitch P=1.25After installation, the length is about =10.6*1.25=13.25mm
