Performance Tool 12-Point Combo Wrench 2-3/8 in - Durable Torque

In this review the Performance Tool W355B 12-point combo wrench is judged on durability, fit, and usefulness for heavy-duty work. The bottom line: this 2-3/8 in combo wrench is built for mechanics and serious DIYers who need a sturdy, corrosion-resistant wrench that delivers extra torque on large nuts. The satin chrome finish and drop-forged, hardened chrome alloy steel construction give it the toughness expected in a professional hand tool while the rounded 12-point box end aims to reduce rounding of fasteners and improve leverage under load.

Key Features

• Size 2-3/8 in: Sized for large fasteners commonly found on heavy equipment, this wrench covers applications where smaller wrenches come up short.
• Drop forged and hardened steel: The forged chrome alloy steel construction provides strength and wear resistance for daily workshop use.
• 12-point box end with rounded corners: Rounded corners increase torque transfer while reducing the risk of rounding off bolt heads under high load.
• Professional style raised panel: The raised panel and full pattern design improve grip and make the wrench easier to handle when applying force.
• Satin chrome finish: A polished satin finish resists rust and corrosion while presenting a clean, professional appearance.
• Combo wrench format: Open end plus box end gives access in cramped spaces and the torque advantage of a box-style end on the same tool.

Who It's For

This wrench is best for diesel mechanics, heavy equipment technicians, and anyone working on large fasteners who needs a robust, no-nonsense tool that holds up to regular use. The combination of hardened chrome alloy steel and the 12-point box end makes it suitable where strength and torque are priorities.

Less suitable users include those who only need occasional light home repairs or who require metric sizes; this large 2-3/8 in size is specialized and not ideal as an all-purpose kitchen-drawer tool.

Pros & Cons

Does the satin chrome finish prevent rust?
The satin chrome finish provides good resistance to rust and corrosion but regular maintenance is recommended in harsh environments.
