["Description:\n40 Pcs Professional SAE Tap and Die Set. Taps and dies are cutting tools used to create screw threads. A tap cuts a thread on the inside surface of a hole, creating a female surface which functions like a nut. The die cuts a thread on a preformed cylindrical rod, which creates a male threaded piece which functions like a bolt. Both tools can be used to clean up a thread, which is called chasing.\n\nFeatures:\n40 Pcs Professional SAE Tap and Die Set with Tap Wrench and T-Handle Wrench\nTaps & Hexagon Die With Thread-Pitch range from 4-40 to 1/2\"-20\nIncludes Both Fine & Coarse Threaded Taps & Dies in Imperial Sizing\nProfessional Grade Set in Special Fine Carbon Steel For Excellent Strength\nIncludes: Adjustable & T-Handle Tap Wrenches, Adjustable Die Wrench\n\nSpecifications:\nCondition: Brand New\nMaterial: Alloy Steel\nMeasurement System: SAE/Imperial\nThread Type: NC, NF, NPT\nTaps and Dies Size: M3X0.5, M3X0.6, M4X0.7, M4X0.75, M5X0.8, M5X0.9, M6X0.75, M6X1.0, M7X0.75, M7X1.0, M8X1.0, M8X1.25, M10X1. 25, M10X1.5, \nStorage Box Size: 293x183x30mm/11.54x7.2x1.18\"\nQuantity: 40 Pcs/1 Set\n\nNote:\nPlease allow 1-3mm error due to manual measurement.pls make sure you do not mind before you bid\nDue to the difference between different monitors, the picture may not reflect the actual color of the item.\nThank you!\n\nPackage Content:\n1 x Adjustable Tap Wrench (1/8\" NPT-27)\n1 x T-Handle Wrench\n1 x Die Handle\n1 x Screwdriver\n1 x Screw Pitch Gauge\n34 x Taps and Dies\n1 x Storage for Case"]
