FAQ
Q1: What is the insulation rating and what certifications does this wrench have?
A: The handle of this product is one-piece injection-molded from high-voltage resistant insulating material with excellent high-voltage insulation performance. Suitable for high-voltage electrical work environments, effectively protecting operator safety. Please contact our sales team for detailed technical specifications and certification information.
Q2: What sizes are available? Can I buy individual pieces or do I have to buy a set?
A: This product is available in 11 sizes: 8mm, 10mm, 12mm, 14mm, 17mm, 19mm, 22mm, 24mm, 27mm, 30mm, 32mm. You can purchase individual pieces based on your needs or buy a complete set. Please contact our sales representatives for details.
Q3: What material is the wrench made of? How hard and durable is it?
A: This product is forged from premium alloy steel with full heat treatment process, providing uniform hardness, high strength, and excellent toughness. The precision-machined jaw offers tight grip and accurate torque transmission — built to last.
Q4: What is the difference between open-end wrenches, box-end wrenches, and adjustable wrenches?
A: Open-end wrenches are flexible to use, ideal for quick assembly/disassembly and confined spaces, but have relatively smaller contact area. Box-end wrenches have larger contact area, can handle higher torque, and are less likely to slip. Adjustable wrenches offer size flexibility but with lower precision. Open-end wrenches are the most commonly used basic wrench type with the widest range of applications.
