# Industrial Specification: Fastener Gripper

## 1. Technical Definition
A specialized gripping component within a fastening end-effector designed to securely hold and position fasteners during assembly operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 NÂ·m gripping torque, 0.1-0.5 mm positional accuracy, 15-35Â°C operating temperature**. Failure boundary: **Gripping force drops below 0.3 NÂ·m at 40Â°C due to thermal expansion exceeding 0.02 mm in jaw alignment**, Mechanism: **Differential thermal expansion between aluminum alloy jaws (Î±=23.1Ã—10â»â¶/Â°C) and steel fasteners (Î±=12Ã—10â»â¶/Â°C) causing misalignment and reduced friction coefficient from Î¼=0.35 to Î¼=0.18**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Cyclic loading at 5 Hz exceeding 3 NÂ·m during misaligned fastener insertion | 8 | Fatigue crack propagation in jaw hinge pin (SAE 4140 steel) at stress concentration factor Kt=3.2 | Implement strain gauge monitoring with automatic shutdown at 2.8 NÂ·m load and replace hinge pin with maraging steel (Kt=1.8) |
| Contaminant particle (â‰¥50 Î¼m) ingress between jaw surfaces during 0.3 mm closure | 8 | Hydraulic locking preventing full closure, causing 0.15 mm positional error exceeding servo tolerance | Install 40 Î¼m absolute filtration in pneumatic supply line and add redundant optical position verification at 0.05 mm resolution |

## 3. Key Technical Parameters
