Description
Hex Screws or Hex Bolts are six-sided head fasteners with a threaded shaft, commonly used in construction, automotive, machinery, and equipment assembly. Designed for durability and strength, these bolts are precision-engineered to meet both metric and inch standards. Manufactured using premium stainless steel—SS 304 / SS 316—they provide excellent resistance to corrosion and high strength under tension.
Hex bolts are available in full-thread (DIN 933 / ISO 4017) or partial-thread (DIN 931 / ISO 4014) options to meet various assembly requirements. They are used with nuts or threaded components and are ideal for heavy-duty fastening solutions.
