Williams Comfort Products 1199BBL Combination Wrench 3 3/8 in

Product Description

The WILLIAMS COMFORT PRODUCTS 1199BBL is a combination wrench with a 3 3/8 inch opening, featuring both an open end and a 12-point box end with identical opening sizes. The open end uses a SUPERCOMBO profile with grooves engineered to direct wrenching force away from fastener corners, reducing the risk of rounding. The box end uses a SUPERTORQUE design that places wrenching force on the flat surfaces of the fastener rather than the corners, allowing higher torque application without deforming hex points. Licensed trades and industrial mechanics rely on this wrench for precision fastener work in demanding environments. The satin-chrome finish resists corrosion and provides a clean, non-glare surface.

This wrench is suited for heavy-duty fastener work where protecting fastener integrity under high torque is critical. The 3 3/8 inch opening handles large hex fasteners common in industrial, mechanical, and structural applications. Because both box and open end openings are identical in size, the wrench offers consistent fit from either end. The SUPERTORQUE box end is compatible with all common 6-point hex fasteners and meets aerospace specification AS 954 for 12-point fasteners as defined by AS 870, making it appropriate for precision torque applications where an accurate torque-to-tension relationship is required.

Key Features

• SUPERCOMBO open end directs wrench force away from fastener corners to reduce rounding
• SUPERTORQUE box end applies force to flat surfaces behind fastener points, not the corners, enabling higher torque without deforming fasteners
• Box and open end openings are identical at 3 3/8 inches for consistent fit from either end
• Meets or exceeds aerospace specification AS 954 for 12-point fasteners as defined by AS 870
• Compatible with all common 6-point hex fasteners with performance advantage over conventional box end wrenches
• Satin-chrome finish for corrosion resistance and reduced glare

Compatibility

Designed for use on all common 6-point hex fasteners and meets aerospace specification AS 954 for 12-point fasteners, suitable for industrial, mechanical, and precision torque applications requiring a 3 3/8 inch opening.

Installation Notes

This wrench is a hand tool requiring no power source or special installation. Always confirm the fastener size matches the 3 3/8 inch opening before applying torque. Inspect the wrench for cracks or deformation before each use and do not use damaged tools. Comply with applicable workplace safety standards and torque specifications provided by the equipment manufacturer.
