The set’s varied size range allows you to select the optimal extractor for the specific fastener, reducing the chance of slippage and stripping. Its compact case makes it easy to transport in a tool belt, toolbox, or vehicle, ensuring you have the right size on hand whenever a surprise break occurs. The extractor’s ergonomic shape provides a comfortable grip, even during extended use, and its steel construction tolerates high torque applications, making it suitable for heavy‑duty tasks such as removing seized engine bolts or extracting damaged pipe fittings.

FAQ
What types of fasteners can this extractor remove?
The CMMT14108 set is designed to remove broken studs, bolts, socket screws, and similar fasteners that have snapped or become seized. The range of extractor sizes (1/8‑inch to 3/4‑inch) allows you to tackle a wide variety of diameters commonly found in automotive, plumbing, and construction applications.
How does the left‑hand spiral design differ from standard extractors?
Standard extractors typically have straight flutes that can slip on smooth or damaged screw heads. The left‑hand spiral grooves on the CRAFTSMAN extractors create a self‑locking action as you turn counter‑clockwise, increasing friction and pulling the broken fastener out more efficiently, especially in tight or rusted conditions.
Is the storage case included, and what is it made of?
Yes, the set includes a durable, molded plastic storage case that securely holds all five extractors. The case features a snap‑tight lid and internal slots that keep each extractor in place, protecting the steel tips from impact and corrosion while making it easy to transport.
Can I use these extractors with power tools?
While the extractors are primarily intended for manual use to provide precise control, they can be paired with a low‑speed drill or impact driver if additional torque is required. However, it is recommended to start with hand operation to avoid over‑driving the extractor and to maintain the integrity of the broken fastener.
What does the lifetime warranty cover?
The full lifetime warranty covers any manufacturing defects in materials or workmanship for the life of the product. If the extractors fail due to a defect, CRAFTSMAN will replace them at no cost. The warranty does not cover damage caused by misuse, improper handling, or normal wear from regular use.
