Advantages

The 120-tooth bi-material ratchet provides precise 3° increments for tightening in confined spaces. X-knurl Maxidrive sockets feature improved knurling for easier handling, a neck-down design for narrow access, a Maxidrive profile for optimized contact with fasteners and visible size markings for quick identification. Included extensions, universal joint and spinner extend reach and accessibility. The rugged construction suits professional environments, while the compact case and PRO-STACK compatibility simplify storage and transport.

How to use

Select the appropriate 1/4" socket or bit for the fastener, attach it to the bit holder, spinner or ratchet as needed, and use the ratchet for controlled tightening or loosening. For hard-to-reach fasteners, fit an extension or universal joint to extend reach and improve access. The spinner is suitable for manual screwdriving with bits; switch to the ratchet for higher torque or rapid turning.

Recommendations

Store the set in its PRO-STACK case to protect components and maintain organization. Inspect bits and sockets periodically for wear and replace damaged pieces to ensure safe and effective operation.
