This set is engineered to bring life back to external threads on bolts and studs, as well as internal threads in nuts, making them reusable and ensuring proper fit. It’s a fundamental kit for automotive technicians, mechanics, and anyone involved in maintenance and repair where metric fasteners are common. Made in USA, this set reflects a commitment to quality and precise thread restoration.KEY FEATURES AND BENEFITS: Comprehensive Metric Coverage: Includes a wide range of common metric sizes for both external (dies) and internal (taps) threads, from M6 to M12, covering various pitches. This ensures versatility for a broad spectrum of repair tasks. Efficient Thread Restoration: The specialized rethread dies and taps are designed to clean out rust, burrs, and minor cross-threading, allowing for smooth re-engagement of fasteners and avoiding costly part replacements. Versatile Thread File: The included metric restorer file features 8 different thread pitches, providing a quick and effective solution for less severe thread damage on various sizes of bolts and studs without needing to identify a specific tap or die. Organized Storage: The entire set comes neatly arranged in a high-impact styrene tray with a clear cover, keeping all components secure, organized, and easily identifiable, which prevents loss and saves time.SPECIFICATIONS: Included in Product: 7 Metric Rethread Dies, Sizes: M6-1.00, M8-1.25, M10-1.25, M10-1.50, M12-1.25, M12-1.50, M12-1.75 7 Metric Rethread Taps, Sizes: M6-1.00, M8-1.25, M10-1.25, M10-1.50, M12-1.25, M12-1.50, M12-1.75 1 Metric Restorer File (Millimeters per thread): 0.75, 1.00, 1.25, 1.50, 1.75, 2.00, 2.50, 3.00 SAE Rethread File (Threads per inch): 9, 10, 12, 16, 20, 27, 28, 32 SAE Rethread File (Threads per inch): 11, 12, 13, 14, 16, 18, 20, 24 Tray Type: High-impact styrene tray with clear cover Dimensions of Packaged Set: 7.125″ x 10″ x 0.688″HOW TO USE: Identify Thread Size: Determine the correct metric size and pitch of the damaged thread on your bolt, stud, or nut. Select Tool: For external threads (bolts/studs), choose the appropriate rethread die. For internal threads (nuts), select the matching rethread tap. If the damage is minor or you’re unsure of the exact pitch, consider starting with the metric restorer file. Apply Lubrication (Optional but Recommended): For smoother operation and to prolong tool life, apply a small amount of cutting oil or penetrating lubricant to the threads you are working on. Engage Tool: For Dies: Place the rethread die squarely onto the damaged bolt or stud. Use a wrench or socket on the hex-shaped die to slowly turn it clockwise (for right-hand threads) while applying light pressure. For Taps: Start the rethread tap into the nut or threaded hole, ensuring it’s straight. Use a wrench or socket to turn the tap clockwise, applying gentle, even pressure. For File: Align the correct pitch side of the restorer file with the damaged thread. Carefully run the file over the threads to clean and reshape them. Clean and Check: After turning the die or tap through the damaged section, remove the tool. Clean the threads thoroughly to remove any debris. Test the thread by attempting to thread a new or known good fastener into the repaired thread, or by trying to thread the original fastener if it was only slightly damaged.BENEFITS OF USING LANG TOOLS 15-PIECE METRIC THREAD RESTORER SET (2584): Cost-Effective Repairs: Salvages damaged bolts, studs, and nuts, eliminating the need to purchase costly replacement parts.
