Wiha's Combination Wrenches have a 12-point box-end design with contact points that apply force to the flat sides of the fastener headrather than the cornersto prevent the fastener head from rounding off. The open-end is angled 15 degrees for flipping the wrench between rotations to maximize rotations and the box-end offset 15 degrees for finger clearance and working around obstructions that limit access to the fastener. The wrenches consist of premium-quality tool steel, have a Chrome-plated satin finish for corrosion protection, and the size profiles are boldly stamped on the handle for easy identification. The tools come conveniently stored in a soft modular foam tray for secure, space-saving storage. The foam tray is designed with high visibility tool callouts printed on each tray to easily return tool to its location. Wiha modular foam trays are made of durable laminated tri-layer foam and will fit in most toolboxes and pull out tool drawers. Wiha modular foam tray are the perfect solution for any storage or organization needs.
