Spark Plug Thread Repair Kit M10x1.0 with HSS Tap and 4 Threaded Sleeves

Brief Overview

This spark plug thread repair kit is engineered for shops that need a reliable solution for restoring damaged spark plug holes in cylinder heads. The kit includes a precision-ground HSS tap paired with four threaded sleeves of varying depths, allowing you to match the specific repair depth required by each engine application. Whether you're managing warranty work, fleet maintenance, or high-volume engine rebuilds, this kit prevents costly head replacement by restoring damaged threads quickly and affordably.

For shops handling multiple thread sizes, consider complementary solutions like glow plug re-threading kits or oil drain plug thread repair sets to expand your thread repair capabilities across engine service work.

Key Features

• HSS Tap (M10x1.0): Hard steel construction resists wear through multiple uses
• Hexagonal Drive (10mm): Direct compatibility with standard tap wrenches and ratchets
• Four Threaded Sleeves (M8x1.0): Variable depths (9.5mm, 11.5mm, 12.7mm, 19mm) accommodate different damage depths and engine designs
• Matte Black Coating: Reduces glare during precision work and provides corrosion resistance
• Compact Design: Lightweight, portable kit fits easily into tool drawers or service carts

Why Resellers Choose This Kit

Margin Driver: Thread repair kits command strong margins on labor-intensive engine work. A single spark plug hole repair eliminates the need for a €500+ cylinder head replacement—customers pay accordingly.

Recurring Revenue: Engine overhauls, warranty claims, and fleet maintenance create consistent demand. Stock multiple kits to capture repeat orders from high-volume shops.

Skill Barrier: Shops without thread repair capability often outsource this work or replace heads unnecessarily. Offering this kit as part of your engine service package increases customer retention and shop profitability.

Wide Application: M10x1.0 taps are standard across many engine families (European, Asian automotive). This size is more versatile than niche alternatives.
