Product Introduction
Hex Bolt Din 933 is a fully threaded hex bolt conforming to German industrial standard DIN 933. It's usually made of carbon steel, alloy steel or stainless steel with high strength and good corrosion resistance. The grade ranges from 4.8 to 12.9, size varies from M6 to M48, surface treatments include galvanizing, blackening, hot-dip galvanizing, etc. It's widely used in construction, machinery, automotive, electronics and electrical fields.
Product Advantages
High-Strength Material Ensures Durability
Hex Bolt Din 933 is manufactured from high-strength carbon steel or stainless steel, with a tensile strength exceeding 800 MPa, far surpassing the 400-600 MPa of ordinary bolts. This material, undergoing heat treatment and surface hardening, maintains stable performance in high-load and frequently vibrating environments, extending service life by approximately 50% compared to regular bolts. Its durability is particularly suited for fields with stringent fastener requirements, such as construction and machinery manufacturing.
Precision Manufacturing Process Guarantees Dimensional Accuracy
Hex Bolt Din 933 employs cold forging (for M2-M24) and hot forging (for M24-M100) processes to ensure thread and hex head dimensional accuracy in line with DIN 933 standards. Cold forging achieves a bolt surface finish of Ra 1.6μm and thread accuracy of grade 6g, ensuring tight fitting with nuts and reducing loosening and thread stripping. This high-precision manufacturing process enhances installation efficiency by 30% in mechanical equipment, bridge structures, and other sectors.
Excellent Corrosion Resistance
The surface of Hex Bolt Din 933 undergoes galvanizing or passivation treatment, forming a dense protective film that effectively resists erosion from moisture, salt spray, and chemicals. Its corrosion resistance exceeds 500 hours, 150% higher than the 200 hours of ordinary bolts. This characteristic makes it ideal for outdoor engineering or marine environments.
High Torque Carrying Capacity
The hex head design of Hex Bolt Din 933 is optimized to withstand higher torques, reaching a maximum torque value of 40 N·m, about 30% higher than that of ordinary bolts. This design ensures that the bolt does not strip or damage easily during tightening, providing more stable connection strength suitable for heavy equipment or high-vibration environments.
Customized Production Capabilities Meet Diverse Needs
Hex Bolt Din 933 supports customized production through CNC and machining technologies, catering to client demands for special sizes, materials, and surface treatments. For instance, in the aerospace sector, nickel-plated or zinc-nickel-plated bolts are available, further enhancing corrosion and wear resistance. This flexibility adapts Hex Bolt Din 933 to more industries and application scenarios.
