Application

The M12 FUEL INSIDER Extended Reach Box Ratchet, No. 3050-20, is designed for under hood, undercarriage, and interior applications for aftermarket service, commercial trucks, heavy equipment, and paint and body technicians. Professionals will be better equipped to complete timing jobs, access water pumps, remove strut towers, grounding bolts, sway bar links, and many other necessary applications on the job.

Origin

This solution was developed to solve the challenge of previous size constraints limiting access, performance tradeoffs, and productivity loss due to the need to switch between multiple solutions. The focus was to deliver the smallest profile with the best balance of speed and torque and the ability to insert sockets directly into the head of the tool, eliminating extra size from the anvil and standard socket connection.  

Features and benefits

  • The M12 FUEL INSIDER delivers unrivaled access with over 3/4lower profile, delivering the smallest head profile size in the industry when compared to cordless competitors, and even rivaling access of manual solutions. The INSIDER allows users to reach deep applications reducing the need to reach for a hand tool and increasing productivity.  

  • Improving access and safety on the job, this ratchet features an extended reach neck for ultimate access and protection from knuckle busting in hard-to-reach locations.  

  • The INSIDER eliminates common compromises needed to complete the job. Providing pass-through capability up to 15mm or 9/16” SAE, dual LEDs for increased illumination, and cordless performance in the size of a manual tool, this solution easily integrates into a technician’s current fastening lineup with the inclusion of anvil and magnetic hex adapters. 

  • The M12 FUEL INSIDER Extended Reach Box Ratchet has a 5-year warranty and the included INSIDER Box Ratchet sockets stand by our lifetime guarantee.
