flat head machine screws

Our Slotted Cheese Head Machine Screws are a classic and highly economical fastening solution, manufactured to the DIN 84 standard for guaranteed consistency and reliability. Made from Grade 4.8 steel, these screws are designed for general-purpose, low-stress applications where a simple and effective fastener is required. With a traditional slotted drive and a functional cheese head, they are a staple in electronics, light machinery, and mass-production assemblies. A protective zinc plating provides good corrosion resistance, making them a dependable and cost-effective choice.

Product Details

This screw is defined by its simple, traditional, and functional design. The “cheese head” features a cylindrical shape with a flat top and a flat bearing surface, providing a solid contact area for clamping. Its height offers a deep slot, making it easy to drive with a standard flat-blade screwdriver.

As a “machine screw,” it has a uniform, straight-shank thread designed for use with a pre-tapped hole or a nut. This ensures a precise, secure, and repeatable fastening. The screw is manufactured from Grade 4.8 steel, a standard commercial-grade carbon steel suitable for a vast range of applications that do not require high tensile strength. The entire fastener is produced through a cold forming process for consistency and strength. A variety of finishes are available, with zinc plating being the most common, offering a protective layer against corrosion in indoor or dry environments.
