PROTO® OFFERS MORE THAN JUST TOOLS. WHAT WE REALLY OFFER OUR CUSTOMERS IS: PEACE OF MIND. Three miles down in the earth at the bottom of a coal mine. An oil rig in the Indian ocean. A battlefield in a war torn country. These are places where keeping the work going is mission critical because lives may be at stake. Our customers work tough industrial jobs in extreme environments and the impact of injury or work stoppage can be catastrophic and costly. That’s why they demand the most durable and safest tools in the world.When they buy from PROTO® they aren’t just buying tools. What they are really buying is confidence that our tools will help keep them working longer and safer. To ensure this, the PROTO® brand must always be unique in the marketplace, relevant to our customer’s work style, and authentic to our company’s values and heritage. Lastly, these objectives must be implemented in a consistent manner in order to build recognition and trust in the PROTO® brand Features Striking box-end wrenches have an offset handle that allows access to fasteners in tight spaces. They have a block shape on one the end of the handle that is struck with a hammer to loosen or tighten a fastener. Wrenches are SAE (inch) size with an opposite end having an enclosed head end (box end) that fits around the entire head of the fastener for a more secure grip while turning compared to an open end. The 12-pt. Design has additional grooves that make it easier to connect with the head of the fastener and connect at more angles for better accessibility compared to a 6-pt. wrench.
