Loksun Thread Repair Kit 61-Piece — UNC, UNF & Metric Chasers, Dies, Color-Coded Heat-Treated Set

The Loksun 61-piece Thread Repair Kit is a complete set of UNC, UNF and metric thread chasers, dies, files and pitch gauges designed to restore, clean and identify damaged threads quickly and reliably.

This organized kit gathers everything a mechanic or maintenance pro needs to recover worn or corroded threads without replacing components. It combines 28 chaser taps, 28 chaser dies, three dedicated thread-restorer files and two pitch gauges (standard and metric) in a rugged carrying case. Color-coding for UNC (silver), UNF (black) and Metric (gold) makes fast selection simple, and the heat-treated steel construction balances toughness with precise cutting geometry for dependable use on automotive, industrial and equipment threads.

What sizes and thread systems are included and how do I pick the right one?

The kit covers a wide mix of common imperial and metric sizes so you can match the original thread profile. Use the included pitch gauges to confirm thread pitch, then choose the corresponding chaser tap or die by color and size marking. Chasers are designed to clean and reform threads rather than cut away large amounts of material.

• 28 chaser taps across UNC, UNF and metric ranges for internal threads
• 28 chaser dies for external threads and studs
• Two pitch gauges for fast standard vs metric identification
• Color-coded finishes: silver (UNC), black (UNF), gold (Metric)

How durable and accurate are the tools for repeated professional use?

Each component is made from premium heat-treated steel or carbon steel to improve hardness and resist wear during repeated thread restoration jobs. The chasers and dies are engineered to preserve thread form while removing rust, paint and damage, giving accurate re-engagement with mating parts. With correct use and occasional light lubrication, the set holds up well in shop environments.

• Heat-treated steel construction for lasting service life
• Chaser geometry restores threads without excessive material removal
• Thread files for coarse restoration in damaged or rounded holes
• Carrying case prevents loss and protects cutting edges

How do I use this kit safely to fix threads on engines or machinery?

Start by cleaning the area and checking thread pitch with the gauges, then run the correctly sized chaser tap or die by hand to reshape threads. Avoid power tools for initial passes—controlled, straight engagement prevents cross-threading. Use light cutting oil or lubricant where appropriate and finish with a thread file for heavily damaged areas before re-tapping.

• Verify pitch with the included gauges before selecting a chaser
• Turn chasers by hand first, then use a wrench if alignment is perfect
• Apply light lubricant to reduce friction and protect edges
• Use files to restore heavily rounded or deformed thread starts

What comes in the case and how is it organized for easy transport?

The kit is supplied in a heavy-duty plastic case molded to hold each chaser, die, file and gauge in its own slot so parts stay protected and visible. Labels and the color-coding system let you identify the correct chaser quickly on the bench or in the field. The case closes securely for safe transport between job sites.

• Molded slots for 28 taps, 28 dies, 3 files and 2 pitch gauges
• Color-coded pieces reduce selection errors during repairs
• Compact, lockable plastic carrying case for workshop or van
• Clear markings on each tool for quick size checks

Who this kit is for: The Loksun 61-piece Thread Repair Kit is ideal for automotive technicians, maintenance teams, hobby mechanics and industrial fitters who regularly restore or maintain threaded parts. It suits anyone who needs a broad selection of standardized chasers and dies, reliable durability for repeated use, and a portable, well-organized solution for thread maintenance across imperial and metric systems.
