No More Frustration - Remove Damaged Bolts With Ease Get Into Tight Spaces That Other Tools Can't Reach  Features 2-in-1 Multifunctional Wrenches With these offset wrenches you get two useful tools in one; a regular set of closed-end wrenches, but with innovative biting teeth that act as an extractor wrench set, which are exclusive to Olsa Tools. The wrench grips your rounded or damaged bolt(s) and takes it out with ease. The 6-point box end design keeps the load off the corners of fasteners, reducing the risk of rounding nuts and bolts under high torque. Precision Metric & SAE Wrenches You will be able to remove multiple sizes of rounded bolts and nuts using this set of wrenches. The Metric set includes sizes 6x7, 8x9, 10x11, 12x13, 14x15, 16x17, and 18x19 mm and the SAE set includes 1/4 x 9/32, 5/16 x 11/32, 3/8 x 7/16, 15/32 x 1/2, 9/16 x 5/8, 11/16 x 3/4-inches with no sizes skipped. They come in an organizer tray that is great for keeping your wrenches tidied up in your toolbox or drawer, helping you to quickly find the right wrench for the job. Professional-Grade Reliability The wrenches exceed DIN standards for box-end wrenches so you can be confident that your bolt extractor wrench set will be reliable for a lifetime of heavy-duty use. The wrenches are carefully engineered with industrial-grade Chrome Vanadium (Cr-V) steel with chrome plating and polished to perfection, to protect your wrenches from rust for years.
