Hex Screws – High-Performance Fastening for Mechanical and Structural Assemblies
Product Description
Hex Screws, also known as Hex Cap Screws, are precision-engineered threaded fasteners with a hexagonal head used in a wide range of mechanical, automotive, construction, and heavy-duty structural applications. Designed for use with a spanner or socket tool, these screws are manufactured to tight tolerances and are available in full-threaded or partial-threaded variants to suit load-bearing and fastening requirements.
At SM Fasteners, we manufacture and supply Hex Screws in various finishes, grades, and coatings including zinc-plated, black oxide, hot dip galvanized, and stainless steel options. Whether you need bulk industrial supply or custom sizing for your OEM project, our Hex Screws deliver reliable torque strength and long-term fastening integrity.
