Lang Tools 6-Piece NF Thread Restorer Tap Set (2586)

The Lang Tools 6-Piece NF Thread Restorer Tap Set (2586) is an essential tool for anyone needing to repair damaged internal National Fine (NF) threads. This specialized set is expertly designed to rejuvenate compromised threads on nuts, bolts, and other components, effectively cleaning out existing damage and removing nicks and burrs without causing further harm or undercutting the good thread material. Instead of replacing an entire part due to minor thread damage, this set allows for precise and efficient restoration, saving both time and money. Each rethreading tap in this set is crafted to be highly tempered, ensuring superior strength and long-lasting performance. Their unique 6-point design offers versatility, allowing them to be easily driven with standard shop tools such as a socket or wrench, making them highly adaptable for various repair environments, including those with limited access.

KEY FEATURES AND BENEFITS:

• Precise Thread Restoration: Specifically engineered to restore damaged internal National Fine (NF) threads, ensuring a proper and secure fit for mating fasteners.
• Damage Removal without Undercutting: Effectively chases out damaged threads, removes nicks, and clears burrs without compromising the integrity of the existing good threads.
• Enhanced Strength and Reliability: Each tap is highly tempered, providing exceptional strength and extended durability for consistent, reliable performance over time.
• Versatile Tool Compatibility: The 6-point design allows the taps to be used with a standard socket or wrench, offering greater flexibility and ease of use in diverse applications compared to traditional tap handles.
• Comprehensive Fine Thread Coverage: Includes a practical selection of common NF sizes (1/4"-28, 5/16"-24, 3/8"-24, 7/16"-20, 1/2"-20, 9/16"-18), making it suitable for a wide range of automotive, marine, and general mechanical repairs.
• Organized and Protected Storage: Comes in a reusable clamshell package, which keeps the taps organized, protected from damage, and easily accessible.

HOW TO USE:

1. Identify the Correct Size: Select the tap from the set that matches the size and thread pitch of the damaged internal thread you intend to repair.
2. Clean the Area: Before starting, ensure the damaged thread and surrounding area are clean of any dirt, grease, or debris.
3. Align the Tap: Carefully insert the chosen thread restorer tap into the damaged internal thread. Ensure it is aligned straight with the existing threads.
4. Attach Tool: Place a socket or wrench onto the 6-point head of the tap.
5. Begin Turning: Apply firm, consistent pressure and slowly turn the tap clockwise. Do not force it. The tap will begin to clean out and reform the damaged sections of the thread.
6. Work Progressively: Continue turning, backing out every half turn or so to clear any removed material, especially if the damage is significant. This also helps to prevent the tap from binding.
7. Inspect Threads: Once the tap has passed through the entire damaged section and feels smooth, remove it and inspect the restored threads to ensure they are clean and uniform.
8. Test Fit: Test the repaired internal thread by carefully threading in a matching bolt or stud to ensure a proper, smooth fit.
