Proto J5250HTC 3/8 in Drive Pear Head Ratchet 90 Tooth

Product Description

The PROTO J5250HTC is a 3/8 inch drive pear head ratchet designed for professional trade use in automotive, mechanical, and industrial service environments. Built to a long-arm configuration with a 13 inch overall length, this ratchet delivers increased torque leverage compared to standard-length handles. The 90-tooth gear mechanism provides a 4-degree swing arc, allowing operation in tight quarters where full handle sweep is not possible. The reversible head switches drive direction without removing the ratchet from the fastener. ASME specification B107.110-2012 compliance confirms dimensional and performance standards. Weighing approximately 0.963 pounds, it balances reach with manageable hand weight for extended use.

The J5250HTC suits licensed mechanics, millwrights, pipefitters, and maintenance technicians working on equipment with restricted fastener access. The pear head profile keeps the head width to 1.16 inches, allowing entry into recessed bolt pockets and confined drive spaces. The long-arm handle is well suited for under-hood automotive work, mechanical room equipment service, and production-floor maintenance tasks where a standard ratchet cannot generate adequate torque without an extension.

Key Features

• 3/8 inch drive size compatible with standard 3/8 inch drive sockets and accessories
• 90 gear teeth for a 4-degree swing arc, enabling use in confined spaces
• 13 inch overall length long-arm handle for increased torque leverage
• Reversible pear head for quick drive-direction changes without disengaging the socket
• 1.16 inch head width fits into recessed and tight fastener locations
• Meets ASME B107.110-2012 specification for ratchet hand tools

Compatibility

Designed for use with standard 3/8 inch drive sockets, extensions, and adapters. Compatible with any 3/8 inch drive socket set conforming to ASME B107 dimensional standards.

Installation Notes

This ratchet is a hand tool requiring no installation. Technicians should inspect the reversing mechanism before each use to confirm positive engagement in the selected drive direction. Apply appropriate personal protective equipment when working in environments with rotating equipment or pressurized systems. Do not use impact-rated sockets unless separately rated for hand-ratchet use, and never use a ratchet as a substitute for a torque wrench where fastener torque specifications apply.
