This video explains three critical mistakes in #tightening structural #bolts that can cause serious failures in #steel_structures. The first mistake is using impact #wrenches for final tightening — they provide inconsistent #torquefitness and can lead to over- or under-tensioned bolts. Instead, bolts should be snug-tightened with impact tools and then finished using a calibrated torque wrench or the turn-of-nut method. The second mistake is incorrect washer placement, which causes uneven pressure and eventual loosening of connections, especially in slotted or oversized holes. The third mistake is skipping #tension_verification — every high-strength bolt must be tested or inspected to ensure proper clamping force. The video emphasizes that steel doesn’t fail because it’s weak but because people take shortcuts. Proper tools, surface cleaning, calibration, and documentation are essential for safe, reliable bolted joints. Build safely — precision in every bolt matters.
