Apex 85999 Xl Gearbox Ratcheting Wrench Set 13 Pc Sae

Product Description

The APEX 85999 is a 13-piece XL GearBox double box end ratcheting wrench set designed for professional tradespeople who need precise torque control and fast fastener cycling in tight spaces. The set is built from chrome vanadium steel for long-term durability under daily shop and field use. Each wrench features a 12-point ratcheting box end that requires as little as 5 degrees of arc swing to advance the fastener, compared to 30 degrees for a standard box end wrench. The standard box end on the opposing side provides the torque leverage needed to break loose stubborn or corroded fasteners before the ratcheting end takes over for fast run-down.

This set covers a full SAE range across 13 sizes: 5/16 inches, 11/32 inches, 3/8 inches, 7/16 inches, 1/2 inches, 9/16 inches, 5/8 inches, 11/16 inches, 3/4 inches, 13/16 inches, 7/8 inches, 15/16 inches, and 1 inch. The long-pattern handle length increases mechanical advantage on seized fasteners, making it well suited for automotive service, HVAC equipment work, plumbing rough-in, and general mechanical maintenance where a combination of breaking torque and rapid cycling is required. Licensed tradespeople and experienced mechanical technicians are the primary users of this set.

Key Features

• 5-degree arc swing allows ratcheting in confined spaces where standard wrenches cannot cycle
• Off-Corner Loading geometry reduces fastener rounding and improves box end strength
• Long-pattern handle length increases torque capability on stubborn or rusted fasteners
• Chrome vanadium steel construction for precision tolerance and extended service life
• Double box end design combines breaking torque on one end with fast ratcheting on the other
• Complete 13-piece SAE set covers 5/16 inches through 1 inch in a single purchase

Compatibility

Designed as a general-purpose SAE double box end ratcheting wrench set suitable for use on standard SAE hex fasteners across automotive, HVAC, plumbing, and mechanical maintenance applications.

Installation Notes

Ratcheting wrenches are a hand-tool application requiring no power source or special setup. Always confirm fastener size before applying torque to avoid rounding. Inspect the ratcheting mechanism for smooth engagement before use, and do not use extension bars or cheater pipes on wrench handles, as this can damage the ratchet mechanism and void tool integrity.
