Cheese Head Screw
What are Cheese Head Screws?
Cheese head screws are precision-engineered fasteners featuring a cylindrical head with a flat bearing surface and deep drive slot (slotted or hex socket). Their tall head provides increased torque transmission and a clean finish, making them ideal for machine assemblies and electronic devices.
Asiad Steel Industries is a leading manufacturer, supplier, and exporter of high-quality Cheese Head Screws in various sizes, grades, materials, and finishes, delivering reliable fastening solutions across multiple industries worldwide.
