Advantages
The DIN 7504K standard defines self-drilling screws featuring a hex flange head design, offering several key advantages for industrial and construction applications:
The DIN 7504K is a metric thread-rolling screw designed for self-tapping into pre-drilled holes in sheet metal, plastic, and light alloys. It features a pan head with a cross recess (Phillips drive) and is commonly used in fastening thin materials without requiring a pre-formed thread.
Head Type: Pan head (low-profile, rounded top).
Drive Type: Cross recess (Phillips, typically PH or PZ).
Thread Type: Self-tapping thread (forms mating thread during installation).
Material: Steel (usually carbon steel or stainless steel A2/A4).
Surface Treatment: Zinc-plated, galvanized, or phosphated for corrosion resistance.
Standards Compliance: DIN 7504K (Germany), similar to ISO 7049 (international).
| Property | Typical Value |
|---|---|
| Tensile Strength (MPa) | 500–1000 (depending on grade) |
| Hardness (HV) | 320–450 (case-hardened for thread durability) |
| Thread Pitch | Coarse thread (e.g., M3, M4, M5) |
Sheet Metal Assembly: Used in electrical enclosures, HVAC ducts, and automotive panels.
Plastic & Composite Materials: Fastens plastic housings, electronic casings, and lightweight structures.
Furniture & Appliances: Secures thin metal sheets in cabinets, racks, and home appliances.
Automotive Interiors: Used in dashboard assemblies, trim panels, and interior fittings.
Electronics & Consumer Goods: Fastens PCB mounts, battery covers, and small mechanical assemblies.
✔ Self-Tapping – Eliminates the need for pre-threaded holes, reducing assembly time.
✔ Pan Head Design – Provides a low-profile, smooth finish for aesthetic applications.
✔ Phillips Drive – Allows for easy installation with standard screwdrivers or power tools.
✔ Versatile Material Compatibility – Works well with steel, aluminum, plastic, and thin sheet metal.
Pre-drill a pilot hole (diameter slightly smaller than the screw’s minor diameter).
Avoid overtightening (risk of stripping threads in soft materials).
Use corrosion-resistant coatings (e.g., zinc or stainless steel) for outdoor/moisture-exposed applications.
DIN 7985K – Similar pan-head screw but with machine thread (not self-tapping).
ISO 7049 – International equivalent with slight dimensional differences.
DIN 7981 – Countersunk head self-tapping screw for flush mounting.
Common sizes: 3#-6.3 * 130mm-180mm (other metric sizes available upon request).
