Product description

Highlights at a glance

  • Made of premium 304 A2-70 or 316 A4-80 stainless steel, our hex bolts are cold-forged integrally with stable internal structure, no cracks or sand holes. Featuring excellent tensile and shear resistance, they stay tight under heavy loads and frequent vibration, avoiding deformation, thread slipping and loosening to extend service life greatly.
  • With professional pickling and passivation surface treatment, these bolts deliver outstanding rust and corrosion resistance. They withstand humid, rainy, coastal salt fog and weak acid-alkali environments perfectly. 316 grade performs better in marine and chemical working conditions, never getting stuck due to rust like carbon steel fasteners, ideal for long-term outdoor applications.
  • Manufactured strictly in accordance with DIN933 and DIN931 standards, the precisely rolled threads are neat and uniform for smooth screwing and repeated disassembly without thread damage. The flat hexagonal head prevents wrench slipping during installation, improving construction efficiency and ensuring reliable locking performance.
  • Compatible with sleeves, open-end and torque wrenches, our bolts are available in full-thread and half-thread styles with complete metric sizes from M3 to M24. Matched with standard nuts, flat washers and spring washers, they are widely used in machinery, construction, new energy, pipeline, shipbuilding, guardrail and cabinet assembly.
  • Each batch undergoes strict quality inspection, with smooth burr-free matte surface and good oxidation resistance. We provide material spectrum, mechanical property and salt spray test reports. In-stock supply and customized non-standard specifications are supported, with moisture-proof packaging to meet bulk domestic and overseas engineering procurement demands.
    • Frequently asked questions
