Machine Screws
Shop machine screws for clean, secure fastening in pre-threaded holes across metal, machinery, electrical, and general hardware applications. This collection includes a wide range of IFI standard machine screws in a zinc finish, with popular head styles like slotted round head, slotted flat head, slotted pan head, Phillips pan head, Phillips flat head, and Phillips round head. Whether you need small machine screws for light-duty assemblies or bulk machine screws for production work, these fasteners are designed to deliver reliable performance and consistent fit.
Unlike a cap screw, which is typically used in heavier-duty applications and often installed with a wrench or socket drive, a machine head screw is designed for precise fastening into tapped holes or with compatible nuts. These mechanical screws are commonly used in equipment panels, electronics, appliances, brackets, enclosures, and repair work where a tight, accurate hold is required.

Our collection includes zinc-plated machine screws with a variety of head types to help match the needs of your application. Zinc-plated machine screws are a versatile and economical choice for indoor fastening and general-purpose assembly.
