Why this one
Wide capacity range
This single tool handles stud bolts from 5.5 to 19 mm diameter thread, eliminating the need for multiple dedicated extraction tools or socket-style pullers.
Eccentric knurled contact wheel
An internal knurled wheel presses the stud against a fluted bore when the tool is turned, creating a progressive grip that tightens as torque increases.
1/2 inch drive compatibility
The 1/2 inch square drive accepts ratchets, torque wrenches, and breaker bars you already own, giving you the leverage a stud master tool needs to break free seized fasteners.
Simple operation
Slide the tool over the stud, engage the ratchet, and turn.
Built for professional use
Designed to meet the demands of full-time technicians and serious home mechanics alike, this tool belongs in any service bay that regularly encounters stud removal and installation work.
Read the full description
Removing and installing stud bolts is one of those jobs that can eat an entire afternoon if you do not have the right tool. The Teng Tools 2300 is built around a single eccentric knurled contact wheel that presses each stud against an internal fluting, creating a self-tightening grip the harder you turn. That means no collets to size, no set screws to fiddle with, and no limit on whether you are pulling a stud out or threading a new one in.
Capacity spans 5.5 to 19 mm diameter thread, which covers the metric studs you will find on exhaust manifolds, turbo housings, cylinder heads, transmission cases, and countless other flanged joints in automotive and industrial work. One tool replaces an entire tray of single-size extractors, saving space in the box and time on the job.
The 1/2 inch drive square pairs with the ratchets, breaker bars, and torque wrenches already in your roll cab. When a stud is seized with heat cycles and corrosion, that larger drive lets you apply serious leverage without worrying about rounding out a smaller square. For installation, the same mechanism lets you thread studs to a consistent depth under controlled torque.
Whether you are a full-time mechanics tools professional working flat-rate or a weekend builder tackling a head-gasket swap in the garage, the 2300 earns its place by doing one job well across a wide range of stud sizes. Slide it on, ratchet, and move to the next fastener.
