Feature
108-Teeth Precision & 3.3° Swing Arc
The 4101PQ-108 Quick Release Ratchet Handle is built for mission-critical mechanical service:
- Industry-Leading 108-Teeth Mechanism: The defining professional feature of the 4101PQ-108 is its 108-tooth gear. This provides an ultra-fine 3.3° swing arc, the most compact movement in its class. This allows for fastener engagement in extreme “zero-clearance” zones where even 72 or 90-teeth ratchets struggle to reset.
- Recessed Quick Release Button (Q): Features a thumb-operated ball-detent release for rapid socket swaps. The recessed design ensures that sockets are held with absolute security during high-torque pulls but won’t be accidentally released in tight gaps.
- PQ-Series Ergonomic Grip (P): The plain “P” handle series is designed for technicians who prefer a sleek, high-strength plain grip that maintains a slim profile for maximum clearance while providing a balanced feel in the hand.
- Forged Chrome Vanadium Steel: Forged from premium Chrome Vanadium (Cr-V) steel and finished with a high-mirror chrome coating to resist corrosion and ensure industrial longevity.
B2B Procurement & Workshop Efficiency ROI
- Peak Precision for Restricted MRO: This Quick Release Ratchet Handle is the primary choice for Service Managers who need to equip technicians for the most challenging modern engine architectures where standard tools cannot operate.
- Increased Workflow Speed: The 3.3° arc significantly reduces “lost motion,” allowing for faster fastener removal and installation in limited-space scenarios.
- Industrial Compliance: Manufactured to meet and exceed DIN 3122 / ISO 3315 standards, ensuring that despite the fine teeth, the mechanism remains strong enough for professional-grade torque.
What is the benefit of 108 teeth over 90 teeth? The 108-teeth gear in the 4101PQ-108 reduces the swing arc to just 3.3°. This provides even finer control and smoother operation in the tightest spaces where you have almost zero room to move the handle.
Is this ratchet as strong as a 36-teeth model? While 108-teeth ratchets provide more precision, they are engineered to meet the same DIN/ISO professional torque standards. However, they are high-precision instruments and should never be used with “cheater bars” or for breaking loose extremely rusted, oversized bolts.
What does “PQ” mean in the model name? In Hans nomenclature, “P” generally indicates the plain/silver handle version, and “Q” indicates the Quick Release mechanism for fast and secure socket changes.
