Product Overview
Product Application
DIN 7982 is the standard for countersunk head tapping screws with cross recesses. Once tightened, the head of this screw is completely countersunk into the surface of the fastened component, ensuring a flush mounting surface. As a result, it is widely used in applications where a smooth, flush finish is required, such as furniture manufacturing, door and window installation, automotive interiors, and electronic enclosures.
Currently, this standard has been superseded by the international standard ISO 7050, but “DIN 7982” remains one of the most commonly used terms in the fastener market.

Key Technical Specifications
1. Head Profile & Geometry
-
Head Style: Countersunk (Flat head). It sits completely flush with the surface of the material when fully installed, requiring a pre-countersunk hole.
-
Countersink Angle: Standard 90° taper.
-
Drive Types: Typically features a cross-recess, available in two primary formats:
-
Type H: Phillips (PH)
-
Type Z: Pozidriv (PZ)
-
2. Thread & Point Design
-
Thread Type: Spaced, coarse self-tapping thread optimized for high stripping resistance in thin materials.
-
Point Style: * Form C: Sharp cone point (most common for piercing and alignment).
-
Form F: Flat, blunt point (used when clearance behind the substrate is limited).
-
Product Advantages
Self-Tapping Efficiency
Hardened threads cut mating threads instantly, eliminating pre-tapping.
High Strip-Resistance
Coarse pitch provides superior holding power in thin substrates.
Common Questions
Can DIN 7982 replace self-drilling screws (Tek screws)?
No. Self-drilling screws form their own holes, whereas self-tapping screws (7982) require a pre-drilled pilot hole.
What is the difference between DIN 7982 and ISO 7050?
Minor head and recess dimension tweaks. ISO 7050 is international, but they are practically interchangeable.
When to choose Form C (sharp point) vs. Form F (flat point)?
Form C provides precise alignment/piercing. Form F suits shallow clearance where a protruding sharp point is hazardous.
Can these screws be used in plastics and wood?
Yes. The coarse pitch provides excellent engagement in rigid plastics (e.g., PVC) and plywood.
