Klein Tools 68452 Open-End Wrench Set, 7-Piece

The 68452 set holds seven double-open-end wrenches, Klein Cat. Nos. 68460, 68461, 68462, 68463, 68464, 68465 and 68466, plus a roll pouch with a marked pocket for each one. Each wrench has a different size opening on either end, so seven tools cover fourteen fastener sizes. Any single wrench can be reordered individually by its own catalog number if one walks off the truck.

Yes. Both ends are offset at a 15-degree angle, which gives clearance over obstructions and lets you flip the wrench between pulls to reset in a confined space, the situation you hit inside a panel, a gutter, or against a strut run. Straight, non-offset open-end wrenches don't give you that half-swing advantage.

No. Klein's warnings for this set say do not push or hammer the wrench and do not extend the handle length, and to wear approved eye protection. For frozen fasteners use a striking wrench or a breaker bar rated for it. Open-end jaws also load only two flats, so on high torque they round nuts; a box wrench or socket is the better tool there.

Open-end wrenches like these are the choice when you need to slip onto a nut from the side, which is most of what an electrician does: strut hardware, conduit clamps, lug and busbar nuts, motor mounts with the fastener partly blocked. A combination or box set grips all six flats and takes more torque, so it is better for hard-torqued mechanical work. Many trucks carry both; if you are picking one for electrical service work, the double-open-end set with the 15-degree offset covers more of the day.

The wrenches are forged alloy steel with a nickel chrome plating for corrosion resistance, so they hold up to damp van storage and outdoor service work better than bare or black-oxide finished tools. Wipe them down after wet work and return them to the marked pouch pockets.

Complete with the pouch, the 68452 set weighs 2.46 lbs and measures 15 x 11 x 1 inches. That flat profile drops into a tool bag or a bucket organizer without much bulk, and it is light enough to carry up a ladder for MRO and service calls.

Order it as Klein Tools 68452. That is the manufacturer part number for the complete 7-piece open-end wrench set with the pouch, and it is the number to quote for standardizing tool kits across a crew or a facility MRO stock.
