Ground Screw Fasteners | M3-M8 Hex Socket Cap Bolts | 304 Stainless

This DIN912 hex socket screw is a basic part for putting things together mechanically. It holds parts firmly in place for machines, electronics, or robots. It's made from A2-70 stainless steel, which means it's strong and resists rust well for your project. Features and Benefits - A2-70 Stainless Steel - This is 304-series stainless steel (A2) with a tensile strength of 700 MPa (70). It protects against rust in most indoor and damp spots. - Hex Socket Head - You can use an Allen key with this head to tighten it down hard. This is good for fastening parts in tight spots where a regular wrench won't fit. - Smooth Cylindrical Head - This head is smooth, not knurled for hand-tightening. It gives a neat, finished look and works with tools for assembly. - Wide Metric Range - Sizes go from M1.6 to M8. You can find the right fit for small electronics up to bigger machine frames. Applications - Machinery and Robotics: Use these A2-70 stainless steel screws to build frames, attach motors, and secure parts that need a strong hold. - Electronics Enclosures: The M3 and M4 sizes work well for attaching circuit boards, panels, and cases in custom electronic setups. - Automotive and Marine: A2 steel resists moisture, so these fasteners are good for car interiors or freshwater boat uses. For saltwater, A4 grade is better.
