Welcome to Cangzhou Dean Safety & Special Tools Co., Ltd — a trusted manufacturer with over two decades of expertise since 2001. Our Hex Key Wrench Size 30mm, Length 240mm, 45# Steel is precision-engineered to meet the rigorous demands of heavy-duty industrial applications. With an annual export value exceeding US$100 million and serving markets across North America, South America, Europe, Asia, Africa, and Oceania, we bring unparalleled quality and reliability to every tool we produce. This Allen Key Hex Driver combines robust material, ergonomic design, and exacting manufacturing standards to deliver exceptional torque and durability for large fasteners.
Product Overview & Key Features
Our 30mm hex wrench is crafted from 45# medium carbon steel, known for its excellent balance of strength, toughness, and wear resistance. After precise forging and machining, the tool undergoes a standard heat treatment process to achieve optimal hardness — typically HRC 45–50 (hardness can be customized upon request). The L-shaped design provides a longer leverage arm (240mm) for higher torque output while remaining compact enough for storage.

Detailed Advantages & Customer Benefits
- High Torque Transmission: The 240mm long arm generates substantial leverage, making it effortless to tighten or loosen large bolts (e.g., M20, M24) that require 30mm hex sockets. This reduces operator fatigue and increases work efficiency.
- Superior Material Strength: 45# steel offers balanced tensile strength (~600 MPa) and yield strength (~355 MPa) after heat treatment, ensuring the tool resists bending or breaking even under extreme loads.
- Precision Fit: Each hex key is machined to strict tolerances (ISO 2936 or equivalent standard) to prevent slippage and damage to fastener heads. Corners are slightly chamfered for smooth insertion.
- Durable Surface Protection: Optional black oxide coating provides corrosion resistance and reduces glare in bright work environments. Standard plain finish is also available.
- Versatile Applications: Ideal for heavy industries such as mining equipment repair, wind turbine maintenance, railway track bolting, steel structure assembly, and large agricultural machinery.
- Customization Options: We offer customized length, hardness, surface treatment, and packaging to meet specific OEM or aftermarket requirements. Minimum order quantities are flexible.

Frequently Asked Questions (FAQ)
-
Q: What materials are available for this hex key besides 45# steel?
A: We can also produce using 40Cr, 42CrMo, or S2 alloy steel upon request. However, 45# steel offers the best cost-performance for most industrial applications. -
Q: Is the 30mm hex key hardened all over or only at the working end?
A: The entire L-shaped bar is through-hardened to ensure uniform strength and wear resistance. The hardness range is typically HRC 45–50, but we can adjust according to your needs. -
Q: What is the tolerance on the hex size?
A: Our manufacturing tolerance is within ±0.05mm for the hex end, which meets international standards (ISO 2936). This ensures a snug fit without gaps. -
Q: Do you offer a set of multiple hex key sizes?
A: Yes, we provide custom sets in pouches, boxes, or rolls. Please let us know your required size range and quantity for a tailored solution. -
Q: Can the surface be plated or coated for rust prevention?
A: Absolutely. Options include black oxide, phosphate coating, zinc plating, or even stainless steel material (e.g., 304/316) if needed. Standard finish is plain with anti-rust oil. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ for stock sizes is around 100 pieces. For custom orders, MOQ may vary depending on specifications. We accept small trial orders to test quality. -
Q: How long does shipping take to North America?
A: Typically 25–35 days by sea from Tianjin or Shanghai. Express delivery (DHL, FedEx) is also available for urgent samples or small shipments. -
Q: Do you provide a warranty for these hex keys?
