Product Description

The Metric Hex Bolts M4x50 (also known as M4-50 Hex Head Screws or DIN 933 Hex Cap Bolts) are standardized fasteners with an M4 thread diameter and 50mm length, featuring a full-threaded design for universal compatibility. Manufactured from Grade 8.8 steel or corrosion-resistant A2/A4 stainless steel, these bolts comply with DIN 933 standards, offering a tensile strength of 800 MPa (steel) or 500 MPa (stainless). The hexagonal head requires a 7mm wrench and delivers a recommended torque range of 2.5-3.1 Nm. Surface treatments include zinc plating (5-8µm) for rust prevention or plain finish for indoor applications. With a temperature tolerance of -50°C to +250°C (steel) and -70°C to +300°C (stainless), they are widely used in machinery assembly, automotive frameworks, and structural engineering. Key advantages include precise dimensional accuracy and vibration resistance, though steel variants may require anti-corrosion maintenance in harsh environments. Typical applications involve securing metal brackets, electrical panels, and industrial equipment components where high shear strength is critical.
