Gearwrench 83504 Hex Key Set Metric Sae L-handle

Product Description

The GEARWRENCH 83504 is a combination L-handle hex key set covering both SAE and metric sizes in a single kit. The SAE range runs from 0.050 to 3/8 inch, while the metric range spans 1.5 to 10 mm, making it a practical go-to set for technicians working across mixed-fastener systems. The L-handle design provides two points of engagement: the short leg for torque and the long leg for reach into recessed fasteners. This set is used by HVAC technicians, plumbers, electricians, and general service professionals who regularly encounter hex socket fasteners on equipment, panels, and assemblies.

This hex key set fits into general trade service work where both inch and metric fasteners appear on the same job. Common applications include tightening or removing set screws on motors, pulleys, and shaft collars, adjusting components inside electrical enclosures, and servicing imported equipment with metric fastener specifications alongside domestic SAE hardware. The L-handle form factor is well suited to confined spaces where a T-handle or folding set cannot fit cleanly.

Key Features

• Dual measurement coverage: SAE (0.050 to 3/8 inch) and metric (1.5 to 10 mm) in one set
• L-handle design provides leverage on the short leg and extended reach on the long leg
• Useful for set screws, recessed fasteners, and hex socket cap screws across trade applications
• Compact individual keys allow access in tight clearances where folding sets cannot reach
• Single kit eliminates the need to carry separate SAE and metric sets on service calls

Compatibility

Designed as a general-purpose L-handle hex key set compatible with standard hex socket fasteners in both SAE and metric sizes across HVAC, plumbing, electrical, and mechanical service applications.

Installation Notes

Select the correct key size before applying torque to avoid rounding hex sockets. Inspect keys periodically for wear or deformation, as a worn key can damage fasteners. For high-torque applications, use the short leg for driving to reduce the risk of key flex or slippage.
