Mueller-Kueps 800640 4-Piece 90 Degree Socket Adapter Kit 3/8 & 1/2 Drive

The Mueller-Kueps 800640 is a 4-piece 90° socket adapter kit designed to give technicians access to difficult, hard-to-reach fasteners that straight ratchets and extensions simply cannot address. By redirecting drive force at a true 90-degree angle, these adapters eliminate the need for awkward tool positioning in tight engine bays, chassis areas, and confined workspaces.

Key Features:

• 4-piece kit includes two 1/2" drive and two 3/8" drive 90° adapters
• DUO-DRIVE design provides both an inner square drive and outer hex drive for maximum versatility
• Color-coded, spring-loaded joints for quick size identification and secure socket retention
• Compatible with standard extensions and ratchets for modular use
• Conveniently organized and stored on an included rail for easy access and inventory at a glance
• Compact 90° profile offers better torque transfer and control compared to bulky universal joints

Ideal for professional automotive, truck, and powersports technicians who regularly encounter obstructed or confined fastener locations. The Mueller-Kueps 800640 kit ships fully assembled on a labeled storage rail, ready for immediate shop use.
