Count On Tools Inc. announces that it now carries PB Swiss Tools’ Rainbow 100 degree Hex Keys. The color-coded features of the Rainbow Series set them apart from the rest by giving an indication of size to every tool. They feature a 100 degree angle at the particularly short key part and the ballpoint. The hex keys are chrome-plated with a powder-coated color finish for protection against corrosion. They feature chamfered corners for easy insertion into screws. Additionally, they provide precision and regularity with tolerances smaller than a human hair. Each tool is labeled with the serial number for additional security. The hex keys also features a ballpoint end that allows any user to turn the screws with an angle of up to 30 degrees. The hex keys in sizes 1.5-10 mm are available as individual tools or in a set. For more information, visit www.pbtools.us.
