VEVOR Thread Restorer Kit 61-Piece — UNC, UNF & Metric Thread Chaser Set, Heat-Treated Steel with Storage Case

VEVOR's 61-piece Thread Restorer Kit is a complete tap, die and thread-file set engineered to clean, repair and restore damaged UNC, UNF and metric threads quickly and reliably.

Whether you’re refreshing corroded bolts on an engine block or tidying stripped fasteners on household hardware, this kit groups hardened taps, dies and thread files in a compact case for mechanics and DIYers. Heat-treated steel construction (HRC 55–62) provides wear resistance and keeps cutting edges stable, while color-coded sizing speeds tool selection on busy jobs.

What sizes and standards are included so I can match bolt threads?

The set covers common American and metric threads used in automotive and machinery work. You get UNC and UNF sizes for imperial bolts plus a broad range of metric pitches to handle most repair needs.

• UNC (silver): 5/8"-11, 9/16"-12, 1/2"-13, 7/16"-14, 3/8"-16, 5/16"-18, 1/4"-20
• UNF (black): 5/8"-18, 9/16"-18, 1/2"-20, 7/16"-20, 3/8"-24, 5/16"-24, 1/4"-28
• Metric (gold): M14x1.5, M12x1.75/1.5/1.25, M11x1.5, M10x1.5/1.25/1.0, M8x1.5/1.25/1.0, M7x1.0, M6x1.25/1.0

How does the construction affect durability and performance?

Each tap and die is made from high-grade steel and heat treated to a hard, wear-resistant finish so the tools retain their form through repeated use. The finely ground surfaces reduce corrosion risk and help the chasers cut debris without removing excessive material from original threads.

• Heat-treated steel rated HRC 55–62 for long life
• Finely ground cutting faces for consistent contact and reduced chatter
• Color-finish coding (silver, black, gold) for quick standard identification

What extras are included to make on-site repairs easier?

A molded storage case keeps every piece organized for fast access and transport between jobsites. The kit also includes three thread files with removable protective covers so you can deburr or re-profile odd pitches and damaged threads safely.

• Sturdy foam or molded tray keeps taps, dies and files secure
• Three thread files with plastic guards for safe handling and storage
• Compact footprint fits in a toolbox or workbench drawer for easy portability

How should I use the kit to avoid further thread damage?

Start by matching the bolt or hole to the correct size and standard, then use a penetrating lubricant and gentle, steady pressure when chasing threads. Work the tap or die a few turns forward and one back to clear chips; finish with a thread file for minor pitch correction if needed.

• Identify standard and pitch before engaging the thread chaser
• Use cutting oil and back off frequently to clear debris
• Finish with the appropriate thread file to restore fit and engagement

Who is this for: The VEVOR Thread Restorer Kit is built for automotive technicians, machine shop workers, and home mechanics who regularly encounter corroded or damaged fasteners. It’s also useful for restoration hobbyists and maintenance teams who need a durable, organized solution to recover threads on bolts, studs and tapped holes without replacing expensive components.
