RethreadingThreading Tool Selection Matrix
Use this technical specification guide to select the right material grade and geometry for your thread cutting or extraction application.
| Tool Category | Material Composition | Thread Specifications | Optimal Application | Key Performance Feature |
|---|---|---|---|---|
| High-Speed Steel Taps | Precision-ground M2 HSS | UNC, UNF, Metric (6H Class) | Machining & production thread cutting | High thermal resistance & sharp edge retention |
| Alloy Steel Hex Dies | Heat-treated Carbon Tool Steel | UNC, UNF, Metric, NPT | Manual rethreading & external cutting | Hexagonal shape fits standard sockets and wrenches |
| Spiral Screw Extractors | Chrome Vanadium / Hardened Alloy | #1 to #5 (1/8" to 3/4" studs) | Extracting snapped studs & frozen screws | Left-hand spiral bites tighter under increased torque |
| Left-Hand Stub Drills | High-Speed Steel (M2) | 5/64" to 19/64" diameters | Pilot drilling broken fasteners | Reverse rotation often backs out fastener while drilling |
| Nu-Thred Restoring Files | Special hardened tool steel | 8 Pitch sizes per file (SAE/Metric) | Restoring bruised external threads | Reforms thread crests without reducing stud diameter |

Frequently Asked Questions
Century threading tools utilize premium grade M2 High-Speed Steel (HSS) for heavy production cutting and heat-treated high-carbon tool steel for manual maintenance and rethreading applications. All tools undergo precision heat treatment to achieve Rockwell hardness ratings optimized for clean thread cutting and long working edge life.
Thread restoring files clean, repair, and reform bruised or damaged external thread crests without removing metal. Cutting dies cut new threads and remove material, which can weaken an existing damaged fastener. Restoring files allow maintenance technicians to save OEM fasteners directly on the machine or vehicle.
Left-hand drill bits rotate counter-clockwise. When drilling a pilot hole into a broken right-hand thread fastener, the cutting torque and heat generated by the left-hand bit frequently loosen and back the fastener out before you even need to insert a screw extractor.
Yes. We offer customized packaging options including industrial bulk cartons, clamshell blister packs, wooden index boxes, and private-label branding for qualified overseas distributors, industrial buying groups, and OEM programs.
