Bolt Usage Tips

Bolts and nuts are fundamental fasteners in industrial applications. Proper use can improve equipment safety and assembly efficiency. First, select the appropriate material (stainless steel/carbon steel, etc.) based on the environment (e.g., high temperature, corrosion) and match the thread specifications (e.g., M6-M24 thread). During installation, ensure a good thread fit. Tightening torque should be controlled in stages (e.g., pre-tighten by 30% torque and gradually increase to 100%) to avoid overload (typical value: 20-150 N·m for 8.8 grade carbon steel bolts). For multi-point connections, tighten diagonally to distribute force evenly. In vibrating environments, use anti-loosening washers or locking adhesive (e.g., Loctite 243). Use the appropriate tools to protect the threads during disassembly. Scientific use can extend lifespan and reduce equipment failure.
