Stud extractor for tight spaces - Kukko Quality Tools Inc

The Kukko 53-22 Stud Extractor is a professional-grade tool designed for the efficient and non-destructive removal of seized or broken stud bolts, especially in confined or hard-to-reach areas. Its compact design and robust multi-roller gripping mechanism enable technicians to precisely extract damaged or rusted studs, minimizing collateral damage and labor time.

Key Features

• Compact Form Factor: At 48 mm body diameter and 100 mm length, this tool is specifically engineered for navigating cramped engine bays, behind manifolds, and other restricted areas where conventional tools often cannot reach.
• Secure Multi-Roller Grip: Three eccentrically arranged, internally toothed rollers establish a positive, non-slip grip on studs up to 22 mm, effectively engaging even severely rusted, rounded, or short protruding fasteners.
• Versatile Dual Drive Options: Features a 1/2" internal square drive for compatibility with ratchets and torque wrenches, alongside a 36 mm external hex for use with spanners or impact sockets, ensuring adaptability on or off the vehicle.
• Professional Tool Steel Construction: Manufactured from robust, precision-machined tool steel, both the body and rollers are built for long-term durability and reliable, repetitive use in demanding automotive and industrial shop environments.
• Minimizes Collateral Damage: This tool extracts studs without aggressive grinding or drilling, helping to preserve existing threads and protect delicate components such as aluminum heads, housings, and other critical parts.

Applications

This stud extractor is ideal for professional technicians addressing exhaust manifold studs, turbo and EGR studs, and various cylinder head and engine accessory studs across passenger cars, light trucks, and heavy-duty vehicles. It is also well-suited for industrial maintenance applications, including machinery, pumps, motors, and fabrication work where seized or broken studs must be removed in confined spaces without extensive disassembly.
