CR-V construction - Made from heat treated chrome vanadium steel for strength and durability. Durable finish - Polished chrome plated for long lasting protection and resistance to corrosion. 12-point box end - Doubles the access angles of a 6-point design. - Helps prevent fastener round-off by distributing force to the flat sides of the fastener head rather than the corners. Offset end - Provides finger clearance and makes it easier to reach around obstructions. Key benefits - Enhanced durability and long tool life from heat treated CR-V steel. - Improved grip and reduced risk of rounding with the 12-point box end. - Easier access in tight spaces thanks to the offset end and increased reach around obstacles. Practical use scenarios - Automotive maintenance in cramped engine bays where bolts sit behind hoses or components and clearance is limited. - Bicycle and equipment repairs where bolts are tucked between frame tubes or behind panels. - Home improvement or furniture assembly in tight corners or behind obstacles such as cabinets, appliances, or wall fixtures.
