Proto J31819 Open End Wrench 18 Mm X 19 Mm Double End

Product Description

The PROTO J31819 is a double-ended open end wrench sized at 18 mm and 19 mm, designed for fastener work in tight or open spaces where a box end cannot seat. Forged from steel with a satin finish, this wrench is built for repeated use in demanding shop, field, and maintenance environments. The 15-degree head angle offsets the handle from the work plane, giving the technician clearance to swing the tool in confined areas. It is a standard hand tool for licensed HVAC technicians, plumbers, pipefitters, and general mechanical tradespeople.

This wrench fits metric fastener applications across a wide range of residential, commercial, and industrial service work. The dual-size configuration — 18 mm on one end and 19 mm on the other — reduces the number of individual tools required on the job. It is well suited for equipment service, piping connections, bracket work, and any task requiring a metric open end drive. Both ends are ground to standard tolerances for a reliable fit on hex fasteners.

Key Features

• Double-ended design with 18 mm and 19 mm openings in a single tool
• 15-degree head angle provides clearance in confined work areas
• Steel construction for durability under torque loads

Compatibility

Designed for use with standard metric hex fasteners requiring 18 mm or 19 mm open end drive. Suitable for general mechanical, HVAC, plumbing, and pipefitting service applications where metric hand tools are required.

Installation Notes

This wrench is a hand tool requiring no installation. Ensure the correct wrench size is fully seated on the fastener before applying torque to prevent rounding of fastener heads. Use appropriate personal protective equipment when working on pressurized systems or energized equipment. Always de-energize, depressurize, or lock out equipment per applicable codes before using hand tools on mechanical connections.
