When productivity is on the line and you need to solve problems fast, the Fluke® 87V delivers the accuracy and advanced troubleshooting capabilities you need. Designed specifically to handle complex signals, the 87V industrial multi-meter, allows you to gain productivity by taking the guesswork out of drive system troubleshooting even in loud, high energy and high altitude locations.

Forged from select alloy steel, the Klein Tools 1-Inch Nominal Opening Spud Wrench is designed to withstand high-leverage and heavy loads. It's designed for use with 5/8-Inch bolts and U.S. regular nut types. The extra-duty head area gives maximum strength and durability. Plus, the continuous taper of the handle makes it easy to line up bolt holes.

The GEARWRENCH combination wrenches are durable tools for most jobs. They are made from alloy steel with either a full polish or satin finish that resists rust & corrosion. The off-corner loading design on both ends provides a stronger grip on fasteners, reduces fastener rounding, and delivers up to 25% more torque to the fasteners. Sizes are stamped on the beam for quick, easy, & permanent identification. The box end is offset 15° for increased access to fasteners. Available in stubby & long pattern lengths and 6 & 12 point, the GEARWRENCH combination wrenches are a must have for every toolbox.
