Professional 9/16" SAE four-way angle head wrench with Flank Drive® Plus technology delivering 62% more turning power, nickel-chrome finish, and ASME certified quality.
The 9/16" SAE Flank Drive® Plus Four-Way Angle Head Open-End Wrench (Model SVS18A) is a professional-grade fastening tool manufactured by Snap-on, designed for demanding industrial applications. This wrench features Snap-on's proprietary Flank Drive® Plus wrenching profile on the open end, which "bites" into the fastener head to prevent slipping and rounding of fasteners while delivering up to 62% more turning power and strength compared to conventional open-end wrenches. The tool is constructed from special alloy steel and heat-treated to ensure optimum strength, durability, and reliability in heavy-duty work environments.
The four-way angle head design allows the same size wrench to be used in four different positions, with offset angles at 30° and 60° to the handle for enhanced accessibility in tight spaces and confined areas. The wrench is finished with nickel-chrome plating that provides superior corrosion resistance and makes cleaning and maintenance simple and quick. Measuring 6-9/16 inches in length with a 1-1/8 inch outside diameter and 1/4 inch head depth, this wrench is sized for optimum comfort and balance during extended use. Conforming to ASME® B107.100 standards, this professional tool is ideal for aviation, aerospace, military, defense, oil and gas, power generation, railroad, and general industrial applications.
