galvanized machine Screws

Our Slotted Cheese Head Machine Screw is a classic, cost-effective fastener designed for a wide array of general-purpose applications. Manufactured from Grade 4.8 steel and typically finished with a protective layer of colored zinc plating, this screw is an economical choice for electrical, mechanical, and industrial assemblies. It features a traditional slotted drive and a distinctive “cheese head” with a tall cylindrical profile, making it a reliable and functional component. As a factory-direct manufacturer, we offer these screws at a low price with extensive customization options in materials, finishes, and dimensions.

Product Details

The defining characteristic of this screw is its “cheese head,” which is cylindrical with a flat top and a flat bearing surface. The head’s taller profile provides a good grip for driving tools and is well-suited for use in counterbored holes.

The drive is a traditional single slot, which is compatible with any standard flat-blade screwdriver, making it universally accessible for manual assembly and repair work. As a “machine screw,” it has a precise, uniform thread engineered to fasten into a pre-tapped hole or to be used with a nut, ensuring a secure and reliable mechanical joint. While the primary product is an economical Grade 4.8 steel screw with zinc plating, we can manufacture these fasteners in a vast range of materials to meet specific performance requirements.
