The hex head self-drilling screw is a mechanical fastener with an integrated drill tip for simultaneous drilling and fastening into metal sheets. Diameter ranges from 4 to 12 mm, with lengths between 16 and 200 mm. Made from hardened carbon steel or stainless steel A2/A4, tensile strength ranges from 600–900 MPa. The hex head, with standard height 6–12 mm, allows fast installation using a wrench or power screwdriver. Galvanized, chrome, or epoxy coating increases corrosion resistance and durability in harsh environments.
The drill tip, angled 60–90 degrees, enables drilling without pre-holes. Threads are precisely designed to create strong, uniform connections in steel sheets 0.5–8 mm thick. Common applications include metal structures, industrial profiles, warehouses, and construction equipment. Optimized mechanical design and resistant coating provide long service life and reduce maintenance requirements.You can order and buy Self Drilling Hex Bolt from Iran by contacting us through whatsaap and email.

Method for Selecting the Appropriate Size and Length of Hex Head Self-Drilling Screws in iran
The selection of size and length for hex head self-drilling screws depends on the workpiece thickness and connection type. Screw diameter should match the required tensile strength and shear load capacity. Screw length equals the sum of workpiece thickness, penetration depth into the substrate, plus 1–2 extra threads for secure engagement. For thin sheets, smaller diameter and shorter screws prevent bending and damage. For thick components, length must allow full thread engagement in the substrate. Following ISO or DIN standards and manufacturer technical tables ensures joint safety and durability.
