As a leading manufacturer based in Cangzhou, Hebei, China, with over two decades of experience since 2001, Cangzhou Dean Safety & Special Tools Co., Ltd. proudly presents our Drop Forged Alloy Steel Deep Offset Striking Wrench. This tool is engineered for the most demanding industrial applications, offering exceptional strength and durability. Our commitment to quality is backed by an annual export value exceeding US$100 million, serving markets across North America, South America, Europe, Asia, Africa, and Oceania. We understand that professionals need tools that withstand extreme torque and repetitive impacts, and this wrench is meticulously crafted to meet those challenges.
The deep offset design of this striking wrench provides superior clearance when working on recessed fasteners, making it ideal for heavy machinery, oil and gas pipelines, and structural steel assembly. Each wrench is drop forged from premium alloy steel, then hardened and tempered to achieve optimal toughness and wear resistance. The result is a tool that delivers consistent performance under high-stress conditions, reducing the risk of slippage or breakage. Whether you're a maintenance technician in a shipyard or a rigger on a construction site, this wrench is built to handle the toughest jobs.
Key Features & Technical Specifications
Below are the core characteristics that set our deep offset striking wrench apart from conventional tools:
- Drop Forged Construction: The entire wrench is formed from a single billet of alloy steel through drop forging, eliminating weak points and ensuring a uniform grain structure for maximum strength.
- Hardened & Tempered Treatment: A precise heat treatment process enhances hardness while maintaining ductility, preventing chipping or cracking under heavy impact.
- Deep Offset Profile: The offset angle (typically 30° to 45°) allows the wrench to reach fasteners in confined spaces, such as those on cylinder heads, flanges, or heavy equipment frames.
- Wide Size Range: Available in sizes from 30mm to 80mm, covering a broad spectrum of fasteners used in industrial applications. Each size is clearly marked for quick identification.
- Impact-Ready Striking Face: The large, flat striking surface is designed to withstand repeated blows from a sledgehammer or mallet without deformation.
- Corrosion Resistant Finish: Optional finishes such as black oxide or phosphate coating provide protection against rust and improve grip in oily environments.

Frequently Asked Questions (FAQ)
-
What is the difference between a deep offset wrench and a standard striking wrench?
A deep offset wrench has a bent handle that allows it to reach fasteners located in recessed or obstructed areas, such as on cylinder heads or flanges. Standard striking wrenches typically have a straight or slight offset, limiting their access in tight spaces. -
Can I order a specific size that is not listed in the 30-80mm range?
Yes, we can customize sizes beyond 80mm or between increments upon request. Please provide your required dimensions, and our engineering team will assess feasibility. -
What is the typical hardness of these wrenches?
Our standard hardness range is HRC 38-45, which balances strength and toughness. However, we can adjust the heat treatment to achieve higher hardness (e.g., HRC 48) for specific applications, subject to testing. -
Are these wrenches suitable for use with impact wrenches?
Yes, they are designed to withstand high torque from impact tools. However, we recommend using a manual hammer for the striking face to avoid damaging the wrench's square drive (if any). For impact wrench use, ensure the tool is properly secured. -
What finish options are available?
We offer black oxide, phosphate, and plain steel finishes. For added corrosion protection, a black oxide finish is recommended. Other finishes like zinc plating are available as custom options. -
How are the wrenches packaged for export?
Standard packaging includes individual poly bags, then bundled in a carton or wooden crate depending on weight and quantity. Custom packaging with your logo and branding is available upon request. -
What is the minimum order quantity (MOQ)?
For standard sizes, MOQ is typically 50 pieces per size. For custom sizes or special finishes, MOQ may be higher. Please contact us for a detailed quotation. -
How long does delivery take?
For stock items, delivery can be arranged within 7-15 days after order confirmation. For custom orders, production lead time is generally 20-30 days, depending on quantity and complexity.
