Product Overview
Product Application
DIN 7976 is the standard for external hex head self-tapping screws. These self-tapping screws are typically used for fastening thin metal sheets (sheet metal), plastics, composite materials, or plywood. Their distinctive feature is an external hex head that can be tightened with a wrench or hex socket, enabling them to withstand higher torque than standard Phillips-head screws.
While the DIN 7976 standard has technically been officially withdrawn and replaced by international standards (ISO 1479 or ISO 27018), it remains widely referenced and used in industrial procurement and manufacturing.

Product Advantages
Thread-Forming Efficiency
Self-taps directly into pre-drilled holes, eliminating separate tapping steps.
Strong Thin-Metal Grip
Deep-spaced threads maximize clamping force and vibration resistance.
Common Questions
What is the difference between DIN 7976 and self-drilling screws?
DIN 7976 screws form threads in a pre-drilled hole, while self-drilling screws include a drill point that drills and taps in one operation.
Is DIN 7976 the same as ISO 1479?
ISO 1479 replaced DIN 7976 as the international standard, but DIN 7976 is still widely used in engineering drawings, purchasing specifications, and global trade.
Can you manufacture custom DIN 7976 screws?
Yes. we provides customized dimensions, materials, coatings, packaging, and OEM branding according to customer requirements.
What materials can DIN 7976 screws be used in?
They are suitable for sheet metal, aluminum, plastics, thin steel sections, and other relatively soft materials.
