Product Description

Brief Overview

This 131-piece thread repair set delivers everything your shop needs to restore damaged internal threads across five critical metric sizes. Whether you're handling stripped bolt holes in engine blocks, agricultural equipment, or industrial machinery, this kit eliminates the cost of component replacement and reduces downtime. The set includes matched drill and tap pairs in HSS high-speed steel, plus 125 stainless steel threaded inserts—all organized in a professional blue metal case with foam inserts for tool protection and easy inventory management. For shops that work across multiple thread sizes regularly, this comprehensive kit is far more practical than purchasing individual M6 repair kits or M8 insert systems separately.

Key Features

• Five metric thread sizes included: M5×0.8, M6×1.0, M8×1.25, M10×1.25, M12×1.75
• 125 stainless steel helicoil inserts: 25 pieces each for M5, M6, M8, M10; 10 pieces for M12
• HSS high-speed steel drill and tap pairs: Precision-matched for each size (5.2/6.3/8.3/10.4/12.4 mm drills; corresponding metric taps)
• Blue T-style installation knobs: One for each size—ensures consistent torque and prevents hand fatigue
• Professional metal case: Durable blue steel carrying case with foam-cut tray for tool organization and job-site portability
• Spring punch removal tool: Included for safe extraction of insert tangs after installation
• Hex key included: For minor adjustments and maintenance

Business Advantages for Resellers

This multi-size set significantly improves your shop's throughput and profitability:

• Eliminate costly part scrapping: Restore stripped threads instead of replacing entire components—increases customer satisfaction and repeat business.
• Faster turnaround: All five sizes in one case means no hunting for individual kits; reduces labor time per repair job.
• Margin-friendly model: The stainless steel inserts are durable and reusable; every repair generates labor revenue without consumable pressure.
• Professional presentation: The organized metal case communicates quality to customers and reflects well on your operation.
• Cross-selling opportunity: Stock individual size kits alongside this set to capture customers who need only one or two sizes regularly.
