MADE OF ALLOY STEEL: This metric and imperial hex key set is forged from 40cr alloy steel. After special heat treatment, each wrench has excellent hardness and toughness, and is difficult to deform or break during use. The surface of the material is finely polished and anti-rust treated to form a protective layer that is resistant to wear and corrosion, thus extending the service life of the tool. Double Metric and Imperial Standards: This set contains 18 metric specifications and 18 imperial specifications, covering all normative requirements. This dual standard configuration is suitable for handling imported equipment or multi-standard projects, without requiring multiple toolsets. Each specification is precision machined to ensure it fits the corresponding screws and avoid any risk of tearing. Multi-Specification Coverage: The metric specifications of the product range from 1.27mm to 8mm, and the imperial specifications from 0.05 inch to 5/16 inch, forming a relatively comprehensive range of sizes to meet different needs, from precision electronics to heavy machinery. Small keys are suitable for fine repairs such as glasses, while large keys meet assembly needs, especially for automobiles. Seven design: The wrench adopts a classic seven-way structure, with a long arm for leverage and a short arm for fast rotation. The surface treatment not only prevents rust, but also improves grip comfort and fatigue after prolonged use. The product adopts a unified ergonomic design, allowing you to maintain a constant feeling of control when changing specifications. Versatile application: The 36-piece configuration of the product makes it a practical tool. Metric specifications are suitable for maintenance of mechanical equipment, while imperial specifications are suitable for the maintenance of products that comply with European and American standards.
