# Industrial Specification: Release/Click Mechanism

## 1. Technical Definition
Audible and tactile feedback mechanism in torque wrenches that signals when preset torque is reached

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-340 N·m (0.37-250.7 lbf·ft)**. Failure boundary: **Shear stress exceeding 450 MPa in the cam mechanism or spring deflection exceeding 2.1 mm beyond design limit**, Mechanism: **Hertzian contact stress exceeding 1.2 GPa at cam-roller interface causing plastic deformation, or spring relaxation due to cyclic loading beyond 10^5 cycles at 85% of yield strength**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Over-torque application exceeding 120% of rated capacity | 8 | Cam lobe deformation causing loss of audible click and torque accuracy drift &gt;±8% | Hardened AISI 52100 steel cam with surface hardness 60-62 HRC and torque limiter clutch |
| Lubricant degradation due to particulate contamination &gt;15 μm | 8 | Increased friction coefficient from 0.12 to &gt;0.25 causing inconsistent release force | Sealed bearing assembly with MIL-PRF-81322 grease and 5 μm filtration |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: How does the release/click mechanism indicate when preset torque is reached?
**A**: The mechanism produces an audible click and tactile vibration through a spring-loaded release ball/pawl system that disengages at the precise torque setting, preventing over-tightening.

### Q: What maintenance is required for torque wrench click mechanisms?
**A**: Regular calibration checks, lubrication of precision bearings, inspection of spring assembly for fatigue, and cleaning of adjustment cam surfaces to ensure consistent performance and accuracy.

### Q: Can these mechanisms be customized for different torque ranges?
**A**: Yes, by adjusting spring tension, modifying cam profiles, and using different hardened alloy steel grades, the mechanism can be engineered for specific torque ranges from light-duty to heavy industrial applications.

## 6. Manufacturing Compliance
