Business Advantages for Resellers

High-margin repair offering: Position this as an upsell to customers with stripped drain plugs—repair cost is a fraction of engine replacement, driving customer loyalty and repeat business.

Inventory efficiency: One kit covers multiple repair jobs; the brass inserts are the only consumable component, making this a profitable long-tail seller.

Shop floor confidence: Mechanics appreciate having a complete, pre-assembled solution rather than sourcing individual components.

Why This Kit Outperforms Single-Component Sourcing

A stripped oil drain thread is a threshold decision for many vehicle owners: repair or abandon the engine. By stocking this complete kit, you eliminate the friction of sourcing multiple parts. Customers see a professional, ready-to-install solution—not a patchwork of individual components. The brass inserts grip reliably under pressure, and the included tap tool removes guesswork from rethreading.

Stock this kit and watch stripped drain plugs become a profitable service line, not a customer frustration point.

For shops that also service larger equipment or work on heavier vehicles, consider stocking larger M17x1.5 drain plug repair kits to cover the full service range.
