Socket Head Cap Screws DIN 912 ISO 4762, Grade 10.9 Zinc-Plated Steel (M4 x 18 mm, 500 pcs)

Description

• - High-strength Grade 10.9: Higher tensile strength and yield strength than standard 8.8 screws; suitable for safety-critical constructions and heavy mechanical loads.
• - Precision according to DIN 912: Corresponds to ISO 4762 and features a precise hex socket drive for effective torque transmission and easy installation, including in hard-to-reach areas.
• - Effective corrosion protection: Electroplated zinc coating helps protect the steel screws against rust for durable appearance and functionality indoors and in protected outdoor areas.
• - Metric standard thread: Full or partial thread depending on length; compatible with common nuts and internal threads from M3 to M30.
• - Professional quality for industry and trades: Suitable for mechanical engineering, automotive repairs, and demanding DIY projects; available in flexible quantities.

DIN 912 / ISO 4762 socket head cap screw made of Grade 10.9 zinc-plated steel. Maximum strength in a compact design: This high-strength Grade 10.9 socket head cap screw according to DIN 912 is designed for extremely heavy mechanical loads. Its electroplated zinc coating also provides reliable basic corrosion protection for indoor use and protected outdoor areas. Drive: Hex socket (Allen) for applying high torque without slipping. Grade: 10.9 (high strength), ideal for safety-critical constructions. Finish: Electroplated zinc, providing reliable corrosion protection for standard applications. Standard: Corresponds to the current ISO 4762. Why choose Grade 10.9? A Grade 10.9 screw has a significantly higher yield strength. This means it can be pretensioned more strongly and only undergoes permanent deformation at substantially higher loads. When vibrations, heavy loads, or dynamic forcessuch as those in automotive applications or on enginesare involved, Grade 10.9 provides the necessary safety margin that a Grade 8.8 screw cannot offer. Typical applications for Grade 10.9 While Grade 8.8 is often sufficient for standard DIY needs, DIN 912 Grade 10.9 is used wherever safety and substantial force transmission allow no compromises: Vehicle engineering and tuning: Ideal for suspension components, braking systems, or engine attachments exposed to high vibration and tensile forces. Mechanical and systems engineering: Suitable for heavily loaded gearboxes, presses, or moving machine parts. Steel construction: Used for heavy-duty connections requiring high pretension to prevent components from loosening. Toolmaking: Due to its high hardness and strength, Grade 10.9 is preferred for clamping devices and molds. The selected length is the screw length excluding the head thickness.
