Description

Extend Your Reach and Grip with Precision

Overcome the frustration of recessed fasteners and tight clearances with the Klein Tools 16-Piece Long Hex Bit Socket Set (652216HEXL). Designed for professional mechanics, electricians, and HVAC technicians, this versatile set features extra-long hex bits that provide the critical reach needed to access deep-set screws without scraping your knuckles. The comprehensive collection includes both SAE (5/32" to 1/2") and Metric (4mm to 12mm) sizes, ensuring you are equipped to handle a wide variety of equipment and machinery with a single, organized kit.

Engineered for efficiency and durability, each socket is crafted from high-strength Chrome-Vanadium steel and features a specialized knurled base. This texture allows for a secure, non-slip finger grip, enabling you to hand-start fasteners quickly and precisely to prevent cross-threading before applying final torque. The set comes housed in a compact, rugged carrying case that connects seamlessly with the Klein MODbox™ System, allowing you to stack and transport your tools with ease. With bold, stamped markings for instant size identification, this set keeps your workflow smooth and productive.

Pro-Tip: While long hex bits offer superior reach, the extended length can act as a torsion spring. To avoid stripping screw heads or damaging the bit, ensure the hex is completely seated in the fastener recess before turning. Use the knurled base to hand-thread the bolt first to ensure proper alignment before applying final torque with a ratchet.
