Product Description

The M6x40 stainless screw is a corrosion-resistant fastener designed for secure mechanical connections, featuring a 6mm diameter and 40mm length. Suitable as an M6x40 hex bolt or M6x40 machine screw, it supports applications requiring high tensile strength (≥800 MPa) and durability. Crafted from stainless steel (A2/A4 grade), it operates in temperatures from -50°C to 300°C, ideal for automotive, construction, and industrial machinery. The hexagonal head ensures easy torque application with standard tools, while the threaded design provides reliable clamping force. Advantages include resistance to rust and oxidation, while limitations include potential thermal expansion under extreme conditions. Compatible with standard M6 nuts and threaded inserts for versatile assembly. Requires periodic inspection in high-vibration environments.
