Wright Tool Introduces WrightGrip(TM) Design On New Open-End and Combination Wrenches
BARBERTON, OHIO - October 2002 - Wright Tool Company has introduced WrightGrip(TM), an innovative, high-strength, anti-slip design on the manufacturer's open-end style wrenches. The new design will be standard on all Wright Tool open-end and combination wrenches in sizes up to 1-1/4".
WrightGrip ensures that the open-end wrench fits more snugly on the fastener, preventing the jaws from spreading and keeping the wrench from slipping. WrightGrip has up to 50% more strength than traditional Wright open-end wrenches, and is up to 80% stronger than comparable competitors' wrenches.
The new design incorporates a series of strategically placed teeth or grooves on the insides of the wrench's two jaws. These teeth allow for a better seating of the wrench on a fastener. One fastener corner locks into the groove so the fastener won't slip or twist out of the wrench under load.
The WrightGrip design also includes a slight enlargement of the wrench opening's back end. The additional metal in this high-stress area helps to stiffen the wrench jaws, thus decreasing the chance of their spreading under heavy loads. The enlargement also provides space for radii on the back surfaces to reduce stress concentration.
In addition, the shape of the wrench's back end has been modified. The new modified U-shape design further reduces stress and improves performance.
Traditional open-end wrench designs sometimes allow a fastener to pivot about one of its outer corners, thus causing the fastener to move outward. The result is that the fastener makes contact further out on the wrench which can cause the jaws to spread. Tests have shown that this spreading, along with the corners of the wrench being flattened, can result in the wrench slipping over the fastener corners.
Wright Tool is offering WrightGrip on open-end and combination wrenches in both its professional line and its Cougar(TM) value line.
The improvements to the Wright line of wrenches are the result of the manufacturer's relentless pursuit of quality, innovative design, and extensive research and development. The higher torques required in many applications demand tools with higher strength and performance. Wright Tool has long been known for incorporating such advanced technologies to improve the company's entire line of tools.
Like all Wright tools, WrightGrip wrenches are manufactured in the U.S.A. in accordance with ISO 9001/2000 quality procedures. They are precision-manufactured from WRIGHTALLOY(TM) steel for strength and durability.
