The Stahlwille 4026 Single-end Wrench is the perfect tool for your bolt, nut, and square lock nut needs. Made of high-quality chrome vanadium and finished with a gunmetal coating, this wrench is drop-forged, hardened, and tempered to provide high torque and added leverage. It is also adjustable, with a 22.5-degree jaw offset, making it an ideal tool for use in confined spaces. What sets Stahlwille wrenches apart from the competition is their superior design and construction. Our wrenches are made using high-quality special steels that are subject to continuous quality controls, ensuring that they are particularly durable and robust. They also feature a non-slip finish and are designed to fit comfortably in your hand, even during extended use or when higher forces are applied. Our wrenches are also designed with a reinforced area between the jaw and the shank to reduce the risk of breakage to a minimum. The thumb groove along the wrench handle eliminates material where there is no stress and concentrates it where it is needed, providing extreme load-bearing capacity and maximum flexural strength with a lower weight. We take great pride in the quality and craftsmanship of our products, and we manufacture our wrenches under the most stringent quality control conditions, adhering to DIN 3117/ISO 6787 (B shape) and ASME B107.100 specifications. As a traditional German company from Wuppertal, we have been providing tools valued worldwide for their excellent quality for over 160 years. We offer a comprehensive range of metric, imperial, spline drive, and TORX wrenches, and our tight manufacturing tolerances and reproducible dimensional accuracy ensure that each Stahlwille wrench is as close-fitting as the next. Both our open-jaw and ring wrenches will always firmly hug the fastener head for an excellent power lock. Choose Stahlwille for your wrench needs and experience the difference that superior design, construction, and quality can make.
