Laser-etched scale on the jaw for clear and precise operation. Full-body heat treatment delivers torque exceeding US ASME standards by 30%+ for superior performance. Plastic-dipped handle offers comfortable grip with anti-slip and cold-insulating properties. Available in 6 sizes from 6″ to 18″, ideal for plumbing, automotive repair, machinery assembly, and home DIY.
Key Features
- Forged Premium Alloy Steel — Precision drop-forged from high-grade alloy steel for high density, superior strength, excellent toughness, impact resistance, wear resistance, and long service life.
- Full-Body Heat Treatment, 30% Over ASME — Entire wrench undergoes heat treatment for uniform hardness throughout jaw and handle, delivering torque exceeding US ASME standards by 30%+ — higher strength, greater durability.
- High-Precision Worm Screw — Precision-threaded worm gear rotates smoothly without jamming, enabling quick, accurate, one-handed jaw width adjustment.
- Laser-Etched Jaw Scale — Precision laser markings on the jaw are clear, wear-resistant, and long-lasting for quick size identification and improved work efficiency.
- Plastic-Dipped Handle, Comfortable Grip — Dip-molded handle provides a comfortable, non-slip grip, stays warm in cold weather, and reduces hand fatigue during prolonged use.
- 6 Sizes Available — 6″/8″/10″/12″/15″/18″ sizes to meet various application and jaw opening requirements.
- Rust-Resistant Finish — Black oxide/phosphated jaw surface for rust and corrosion resistance with a robust, professional appearance.

FAQ
Q1: What is the MOQ?
A : The MOQ for standard models is 1 carton (12-120 pcs depending on size), with mixed sizes supported. For custom logo engraving, the MOQ is 500 pcs — please contact our sales team for details.
Q2: Can you provide samples?
A : Yes. We provide free samples (freight collect), usually shipped within 3-5 business days. Custom samples require a sample fee, refundable upon bulk order placement.
Q3: What does “full-body heat treatment, 30% over ASME” mean?
A : Standard adjustable wrenches typically only quench the jaw, leaving the handle with limited strength. Our wrenches undergo full-body heat treatment for uniform hardness throughout, with torque performance exceeding US ASME standards by 30%+ — stronger and more durable than ordinary adjustable wrenches.
Q4: What’s the difference between plastic-dipped and standard handles?
A : Plastic-dipped handles have a PVC coating for more comfortable grip, better anti-slip performance, and warmth in cold weather. Standard bare metal handles feel hard, are cold to touch in winter, and can be slippery. Plastic-dipped handles provide a noticeably better user experience.
Q5: What is the lead time?
A : In-stock items ship within 7 days. Custom orders typically take 25-35 days, depending on order quantity and customization requirements.
Q6: Do you offer a warranty?
A : We offer a 1-year quality warranty. Any non-human-caused quality issues are eligible for free return or replacement — 100% quality guarantee.
