Proto J5449HTC 1/2 in Drive Pear Head Ratchet 90 Teeth

Product Description

The PROTO J5449HTC is a 1/2 inch drive pear head ratchet built for professional tradespeople who need reliable torque transfer in tight service environments. The pear-shaped head measures 0.75 inches in length and 1.69 inches in width, keeping the swing arc compact while the 90-tooth gear mechanism delivers fine 4-degree increments of engagement. At 10 inches overall length, the handle provides enough leverage for most fastener applications without excessive bulk. The reversible head allows direction changes without removing the ratchet from the fastener, which speeds up repetitive work. This ratchet meets ASME B107.110-2012 standards and weighs 1.866 pounds.

The J5449HTC is suited for use in automotive, HVAC, plumbing, and general mechanical service work where a 1/2 inch drive is the appropriate fastener interface. The standard handle style and pear head geometry make it a practical choice for mechanics and service technicians working on equipment access panels, compressor mounts, flanged fittings, and structural fasteners. The 90-tooth count is particularly useful in confined spaces where only a few degrees of handle sweep are available between obstructions.

Key Features

• 90 gear teeth provide 4-degree engagement increments for use in confined spaces
• Reversible pear head allows direction changes without repositioning on the fastener
• 10 inch overall length balances reach and leverage for general service tasks
• Pear head width of 1.69 inches and head length of 0.75 inches reduce clearance requirements
• Meets ASME B107.110-2012 dimensional and performance standards
• Standard handle style compatible with common 1/2 inch drive socket sets

Compatibility

Designed as an OEM-style 1/2 inch drive ratchet compatible with standard 1/2 inch drive sockets, extensions, and accessories conforming to ASME B107.110-2012.

Installation Notes

This ratchet is a hand tool intended for use by licensed mechanics, HVAC technicians, plumbers, and electricians. Before use, ensure the reversing lever is fully seated in the intended direction to prevent unintended fastener movement. Inspect the drive square and gear teeth for wear or damage before applying high torque loads. Do not use with impact drivers or power tools — this is a hand-rated ratchet only.
