Better Tools and Fasteners' (BT&F) new Kobalt Steel Grip Sockets can remove rusted, damaged and severely rounded bolts and nuts, the firm claims.
The new launch grips the flats of a bolt head and squeezes tighter as more torque is applied.
Steel Grip Sockets also provide hands-free holding of bolts and nuts for easy installation and removal in hard to reach places.
Alex Gordon, Director of Marketing for Better Tools & Fasteners, said: "The 'secret' to this phenomenal performance is the internal flexible 'grip' member, which is made entirely of high grade, high strength, alloy steel. This proprietary and patented all-steel technology makes Steel Grip sockets extremely rugged and exceptionally durable."
In metric and SAE sets, the new Kobalt Steel Grip Sockets are available via US hardware retailer Lowe.
