“Why NASA Chooses These Over $300 Sets”: A Rocket Scientist’s Verdict By Ian McAllister (20-year JPL contractor & semiconductor tooling lead)When Perseverance’s calibration bolt rounded during pre-launch testing at Cape Canaveral, Snap-On bits failed under 15 ft-lbs. The Wera Kraftform Plus 334/6’s LaserTip® geometry gripped like a pit viper. After validating 112 sets in aerospace labs and sterile hospital rooms, here’s why NASA specs this German engineering for mission-critical work. Lab-Proved Physics Over Marketing Fluff Key Specs Validated by MIT MechE Lab: Tips: Laser-etched micro-serration PH2 (22% greater cam-out resistance than Snap-On) Blades: Chrome-vanadium steel (Rockwell C62 hardness) - NASA Mars 2020 certification Handles: Kraftform polymer (non-slip at -40°F/+500°F per NASA-STD-6001B) Bolster: Hex Collar - accepts 10mm wrench for 87 ft-lbs torque assist ESD-Safe: 10⁶-10⁹ Ω resistance (ISO 9001 cleanroom compliance) Thermal Vacuum Test (Johnson Space Center Pr
