1161M/A Combination Wrench | 3.2mm–105mm & ⅛”–4-⅛”

Cr-V Metallurgy & 15° Offset Engineering

The 1161M-A Combination Wrench is built for mission-critical mechanical service:

 Master Series is built for mission-critical service across all scales:

• Extreme Sizing Range (3.2mm to 105mm): The defining professional feature of the 1161-A is its versatility. The 3.2mm micro-wrench is designed for delicate instrumentation, while the 105mm (and 4-1/8″) jumbo wrenches provide the massive leverage required for heavy-duty turbine and bridge-work fasteners.
• 15° Offset Box End Architecture: Every wrench in the 1161-A series, regardless of size, features a 15-degree offset ring head. This geometry ensures essential knuckle clearance and allows for high-torque applications in recessed or obstructed environments.
• Forged Chrome Vanadium (Cr-V) Integrity: Manufactured using industrial-grade Cr-V steel, heat-treated for maximum torsional resistance. This prevents the open-end jaws from spreading and the box-end from cracking under the extreme loads generated by 100mm+ fasteners.
• Dual-System Availability (Metric & SAE): Provides a perfect “mirrored” range for international maintenance teams, ensuring a zero-tolerance fit for both metric and fractional hardware globally.

B2B Procurement & Technical ROI

• The “One-Series” Solution: This Combination Wrench series is the primary choice for Procurement Officers because it allows for the standardization of a single high-quality brand across an entire facility, from the electronics lab to the heavy-equipment bay.
• Corrosion-Resistant Industrial Finish: Features a high-mirror polished chrome finish that exceeds DIN / ISO standards, allowing for rapid cleaning and long-term protection against oxidation in harsh environments.
• Structural Safety Compliance: All sizes are engineered to exceed DIN 3113 and ISO 7738 torque requirements, ensuring operator safety during high-leverage “breakaway” torque events.
