The 151A spark-reduced double closed-end offset wrench has two enclosed openings on both ends. It also includes an offset handle to improve access to the nut or bolt where lack of space or clearance prevents the use of a straight wrench. The wrench is drop-forged from copper alloy to impart extra tensile strength to the structure. It is created by adopting German standard DIN838 as basis for its design.
This series of wrench is primarily used in a variety of areas where potential fire or explosion hazard might be experienced. Durable and long-lasting, the product gives stable mechanical functioning.
