Half Moon Ring Wrench (Model 1108M) is a specialized “obstruction” tool engineered for high-torque fastening in curved or cramped industrial environments. Manufactured by Hans Tools from premium Chrome Vanadium (Cr-V), the Half Moon Ring Wrench features a distinct C-shaped profile. This geometry is specifically designed to bypass obstructions such as manifolds, starters, and pulleys, allowing the technician to apply leverage to fasteners that are blocked from a linear approach.

Feature
C-Shape Obstruction Geometry & Cr-V Strength
The 1108M Half Moon Ring Wrench is built for the most difficult mechanical access points:
- Engine-Optimized Arc: The radius of the Half Moon Ring Wrench is calculated to clear common engine protrusions. This makes it an essential tool for adjusting fuel injection pumps, distributor bolts, and exhaust manifold nuts where a straight wrench cannot swing.
- 12-Point (Bi-Hex) Precision: Both ends of the Half Moon Ring Wrench feature precision-machined 12-point profiles. This ensures a secure grip on the flats of the fastener and a 30° engagement arc, providing maximum versatility in confined spaces.
- Cold-Forged Industrial Quality: Each Half Moon Ring Wrench is heat-treated for maximum torsional rigidity and finished in a high-polish mirror chrome that resists industrial oils and prevents corrosion over long-term use.
B2B Procurement & Workshop ROI
- Essential for Automotive MRO: The Half Moon Ring Wrench is a staple for Fleet Maintenance Facilities and Diesel Specialists who frequently encounter “hidden” fasteners behind accessories.
- Increased Service Efficiency: By eliminating the need to remove auxiliary components just to reach a single bolt, the Half Moon Ring Wrench significantly reduces labor hours and improves workshop throughput.
- Comprehensive Metric Sizing: The 1108M series is available in various size combinations (e.g., 10x12mm, 11x13mm, 14x17mm), providing a standardized solution for global industrial applications.
