Hex Nuts | High Tensile Steel BZP (Zinc Plated) | DIN 934

Grade 8 High Tensile Hex Nuts (DIN 934) - BZP Finish

Engineered for maximum strength and long-term reliability, our Grade 8 High Tensile Hex Nuts provide a secure fastening solution for your most critical applications. Featuring a robust Bright Zinc Plated (BZP) finish, these nuts deliver exceptional load-bearing capacity combined with superior protection against corrosion. They are the professional's choice for projects where safety and performance are non-negotiable.

Key Features & Benefits

• Exceptional Strength for Critical Loads: Manufactured from heat-treated Grade 8 alloy steel to handle extreme tension and shear forces in high-stress environments like automotive suspensions and structural steelwork.11

• Superior Corrosion Resistance: Coated with a durable Bright Zinc Plating (BZP) that acts as a sacrificial layer to protect the underlying steel from rust and environmental degradation, extending the life of your assembly.10

• Precision Engineering & Guaranteed Fit: Manufactured to the strict dimensional tolerances of the DIN 934 standard, ensuring consistent quality, precise threading, and perfect compatibility with corresponding metric bolts.22

• Versatile High-Performance Applications: The ideal choice for demanding projects in the automotive, construction, industrial machinery, and agricultural sectors where fastener failure is not an option.15

Applications

These high-strength hex nuts are essential for any application requiring a secure, load-bearing connection. Ideal for both professional trades and advanced DIY projects.

• Automotive & Motorsport: Securing engine mounts, suspension components, chassis frames, brake systems, and drivetrain assemblies.15

• Construction & Structural Engineering: Fastening steel beams and columns, bridge assembly, and anchoring heavy equipment to concrete foundations.11

• Industrial & Agricultural Machinery: Vital for the assembly and maintenance of presses, lathes, bulldozers, tractors, and other heavy-duty equipment subject to high vibration and stress.17

• Advanced DIY Projects: Perfect for vehicle restoration, custom trailer fabrication, building heavy-duty workbenches, and assembling workshop machinery.

Technical Specifications

Our Grade 8 Hex Nuts conform to the DIN 934 standard for dimensional accuracy. Please refer to the table below for detailed measurements corresponding to each thread size.

• Material: Heat-Treated Medium Carbon Alloy Steel

• Strength Grade: Property Class 8

• Finish: Bright Zinc Plated (BZP), CR3

• Thread: Metric Coarse, Right-Hand

Usage & Installation Guidance

• System Integrity: For optimal performance and safety, the grade of the nut must be the same or higher than the grade of the bolt. Always pair Grade 8 nuts with bolts of an equal or higher strength grade, such as Grade 8.8 or 10.9 bolts.25 Using a lower-grade bolt will compromise the strength of the entire joint.

• Proper Torque: Ensure the correct torque specifications are applied during installation using a calibrated torque wrench. This achieves the required clamping force and prevents thread stripping or fastener failure.

• Component Matching: For best results, use with corresponding flat washers (to distribute load) and spring or locking washers (to provide additional resistance to vibration).
