Loksun Thread Repair Kit 61-Pc — UNC/UNF & Metric Chasers, Color-Coded Case, Heat-Treated Steel

The Loksun 61-piece Thread Repair Kit is a complete set of UNC, UNF and metric thread chasers, dies, pitch gauges and files designed to clean, restore and maintain damaged or dirty threads on bolts and threaded holes.

Whether you're rebuilding an engine, servicing industrial machinery, or maintaining hobby projects, this kit groups the most commonly needed thread sizes and tools into one organized case. The set mixes chaser taps, dies, hand files and pitch gauges made from heat-treated alloy for longevity, with a color-coded system to speed size recognition and reduce errors during repairs.

What sizes and components are included in this kit?

The Loksun kit contains 61 pieces covering UNC, UNF and metric standards, supplying both chaser taps and dies plus accessories for accurate restoration. It’s built to handle coarse and fine threads found in automotive and industrial applications.

• 28 thread chaser taps across common UNC/UNF and metric sizes
• 28 matching thread chaser dies for external threads
• 3 compact thread-restorer files for damaged or irregular starts
• 2 thread pitch gauges (standard and metric) to verify pitch quickly

How are the tools built to resist wear and frequent use?

All cutting and rethreading components are manufactured from premium heat-treated steel or carbon steel to improve hardness and service life. These materials help the tools keep sharp edges longer while standing up to repeated use in workshop environments.

• Heat-treated alloy construction for better durability
• Carbon steel chasers designed to resist dulling from metal debris
• Files and gauges made for repeated, accurate measurements and dressing

How does the color-coding and case organization speed up repairs?

The kit uses a simple color scheme—silver for UNC, black for UNF and gold for metric—which lets you pick the correct chaser or die at a glance. Every piece has a dedicated slot in the heavy-duty carrying case to prevent loss and keep sizes grouped when you move between jobs.

• Color-coded tools reduce selection time and minimize mistakes
• Individual molded slots keep chasers and dies from contacting each other
• Compact case fits in a toolbox or workbench drawer for easy portability

What common tasks does this set solve in automotive and mechanical work?

This kit is tailored for thread cleanup and light restoration rather than full thread re-cutting or helicoil inserts. It’s ideal for preparing bolt threads, cleaning corrosion, and restoring thread engagement on engine components, housings, and fasteners.

• Cleaning rusted or dirty internal and external threads on bolts and holes
• Restoring oil hole threads and fastener seats in automotive engines
• Maintaining machinery and equipment where threads are frequently assembled

Who is this for: The Loksun 61-piece Thread Repair Kit is well suited for professional mechanics, industrial maintenance technicians, and serious DIYers who need a broad, durable selection of chasers and dies. If you require occasional thread cleaning or want a comprehensive portable set for the shop, this kit balances coverage, durability and organization without requiring specialist rethreading machinery.
