Proto J5250HTCF 3/8 in Drive Pear Head Flex Ratchet 90T

Product Description

The PROTO J5250HTCF is a 3/8 inch drive, pear head flex ratchet built for professional technicians who need reach and control in tight service environments. The reversible flex head rotates to access fasteners at difficult angles, while the long-arm handle delivers increased torque leverage without added bulk. At 13 inches overall length and 90 gear teeth, this ratchet provides fine arc swing — useful when working in confined engine bays, mechanical rooms, or equipment enclosures where full wrist rotation is not possible. It meets ASME B107.110-2012, confirming dimensional and performance compliance to a published standard.

This ratchet is suited for automotive technicians, HVAC service technicians, plumbers, and industrial mechanics working on bolted assemblies, component R and R, and general mechanical fastening tasks. The 90-tooth gear count means a 4-degree arc swing per click, making it practical in areas where handle travel is restricted. The long-arm configuration reduces the number of handle strokes needed per revolution, saving time on repetitive fastener removal and installation. This is a single-piece tool sold individually.

Installation Notes

This tool is used by licensed HVAC technicians, plumbers, electricians, and mechanics for fastener removal and installation. Inspect the flex joint and ratchet mechanism for damage before each use and confirm the direction selector is fully engaged before applying load. Do not use with impact drivers or apply force beyond the tool's rated capacity. Store dry to prevent corrosion of the internal gear mechanism.
