syizyen 3-Piece Thread Repair Files Kit | SAE & Metric Rethreading Tool with Safety Caps

Complete SAE and Metric Thread Coverage

The syizyen 3 Pieces Thread Repair Files Kit provides three specialist tools that handle SAE UNF 9-32, SAE UNC 11-24, and Metric 0.75-3.00mm threads. This broad coverage supports repairs on automotive components, plumbing fittings, and mechanical assemblies where damaged threads need a precise touch rather than replacement.

Built to Last

Crafted from quality carbon steel and hardened through a heat treatment process, these thread files keep cutting capability after multiple repairs. The sturdy construction helps you approach each job with steady confidence, even on stubborn or slightly damaged threads.

Dual-End Design and Safety

Each file features detachable rubber caps that unlock access to both ends. A non-slip handle provides a stable grip, while the compact, lightweight form makes it easy to carry between jobs or store in a toolbox.

Restore Threads, Don’t Replace

Use the files to revive worn or damaged threads, offering an alternative to full bolt or pipe replacement in many scenarios. In some cases, repairs can be performed without disassembly, helping you save time on routine maintenance or service calls.

How to Use

• Identify the correct size, align the tool with the original thread direction, and apply steady pressure as you work along the grooves.
• Work evenly from end to end, keeping the file perpendicular to the surface for consistent results.
• After use, cap the ends for storage and wipe clean.
