Stud Bolt

  1. Heavy-duty stud bolt standard
  2. Material: Alloy steel (40Cr, 35CrMoA), stainless steel (316L), carbon steel (45#); strength grade 8.8–12.9
  3. Structure: Double-end full thread + middle smooth shank + heavy hexagon nut (thicker flange, higher torque)
  4. Surface Treatment: Phosphating, Dacromet (salt spray ≥1500h), galvanizing, black oxide
  5. Size: Nominal diameter M8–M64, length 50–1000mm; nut thickness 10–50mm (matching bolt strength)

Description

Core features of Stud Bolt with Heavy Nut

  1. Super Preload: Heavy nut’s thick wall enhances torque bearing, ensuring sufficient preload to resist vibration loosening
  2. Double-end Adaptability: Threaded ends connect workpieces and nuts respectively, suitable for flange, equipment base fixed scenarios
  3. Uniform Force: Smooth shank reduces stress concentration, matching heavy nut to improve overall load-bearing capacity
  4. Harsh Environment Adaptation: High-strength material + corrosion-resistant coating, applicable to petrochemical, machinery, construction heavy equipment
  5. Easy Assembly: Heavy nut’s clear hexagon structure facilitates wrench operation, improving installation efficiency
