Socket Head Cap Screws DIN 912 / ISO 4762, Zinc-Plated Steel, Grade 10.9 (M6 x 130 mm, 50 pcs)

Description

• HIGH-STRENGTH GRADE 10.9: Higher tensile strength and yield strength than standard grade 8.8 screws; ideal for safety-relevant structures and heavy mechanical loads.
• PRECISION TO DIN 912: Manufactured to DIN 912, equivalent to ISO 4762, with a precise hex socket drive for efficient torque transfer and easy installation, even in hard-to-reach areas.
• RELIABLE CORROSION PROTECTION: Electroplated zinc coating helps protect the steel screws against rust for lasting appearance and functionality indoors and in protected outdoor areas.
• METRIC THREAD: Continuous or partial thread, depending on length, according to metric standards; compatible with common nuts and internal threads from M3 to M30.
• PROFESSIONAL QUALITY FOR INDUSTRY AND TRADE: Suitable for mechanical engineering, automotive repair, and demanding DIY projects. Available in flexible quantities for different requirements.

Maximum strength in a compact design: This socket head cap screw with hex socket drive, manufactured to DIN 912 and high-strength grade 10.9, is designed for extremely heavy mechanical loads. Its electroplated zinc coating provides basic corrosion protection indoors and in protected outdoor areas. The hex socket drive enables high torque without slipping. Grade 10.9 is suitable for safety-relevant structures, while the zinc-plated surface provides reliable corrosion protection for standard applications. The screw complies with ISO 4762. Why choose grade 10.9? A grade 10.9 screw has a significantly higher yield strength. This means it can be preloaded more strongly and only undergoes permanent deformation at substantially higher loads. When vibrations, heavy loads, or dynamic forces are involved, such as in automotive applications or on engines, grade 10.9 provides the necessary safety reserve that a grade 8.8 screw cannot offer. Typical applications for grade 10.9 While standard grade 8.8 is often sufficient for typical home improvement needs, DIN 912 grade 10.9 is used wherever safety and high force transmission allow no compromises: vehicle technology and tuning, including suspension components, brake systems, and engine attachments exposed to high vibration and tensile forces; mechanical and plant engineering, including heavily loaded gearboxes, presses, and moving machine components; steel construction, for heavy-duty connections requiring high preload to prevent components from loosening; and toolmaking, where grade 10.9 is preferred for clamping fixtures and molds due to its high hardness and strength. The selected length is the screw length excluding the head thickness.
