| Performance Metric | Rating / Measured Threshold | Structural Workspace Behavior |
| Material Hardness Rating | Rockwell Scale: 58 to 62 HRC | S2 steel core resists tip twisting and shaving down under heavy load |
| Torque Threshold Limit | Up to 1.8 N·m (Newton-meters) | Exceeds standard electronic assembly torque needs without cracking |
| Magnetic Flux Strength | Strong localized engagement field | Instantly holds loose 0.6mm screws securely against the bit tip |
| Surface Rust Protection | Manganese Phosphate conversion coating | Resists corrosion from salty skin oils, flux, and isopropyl alcohol |
| Tolerance Deviation Margin | less than 0.02 mm concentricity variance | Fits tightly into screw heads to minimize slip-outs and stripping |
| Tool Station Ecosystems | Supported Driver Handles | Intended Repair Scenarios |
| 2UUL System Rails | Fits 2UUL KAKA Torque Screwdriver and specialized anti-slip manual drivers. | Replacing display screens and re-assembling logic boards under microscopes. |
| Third-Party Drivers | Works with any standard 4mm precision hex socket driver handle. | Fastening battery brackets, replacing camera modules, and fixing charging ports. |
| Magnetic Workmats | Pairs perfectly with the 2UUL ST95 MagDock and ST92 magnetic project layouts. | Keeping trace components safe during detailed micro-soldering tasks. |
| Operational Maintenance Step | Actionable Method Guideline | Primary Goal |
| Step 1: Alignment Inspection | Visually check the bit profiles under a repair microscope before using on high-torque fasteners. | Spot early micro-fractures to avoid damaging rare screw heads. |
| Step 2: Post-Repair De-fluxing | Wipe down the bits using a lint-free cloth lightly dampened with 99.9% industrial isopropyl alcohol (IPA). | Removes sticky rosin flux residue from the magnetic tip valleys. |
| Step 3: Base Remagnetization | Slide the bit bottoms against a magnetizer block if the screw holding force decreases over time. | Re-aligns internal magnetic domains to bring back full pickup power. |
| Step 4: Storage Placement | Always drop the bits vertically back into their designated CNC aluminum base slots immediately after use. | Keeps bits from rolling off the bench, chipping, or getting lost. |
| Step 5: Climate Safeguards | Store the kit inside tool cabinets away from open ultra-sonic cleaners or chemical vapor stations. | Prevents moisture buildup inside the base sockets, ensuring smooth bit extraction. |
