DIN7504 Self Drilling Screw

The DIN7504 Self Drilling Screw is a high-performance fastener designed to drill, tap, and secure materials in a single operation without pre-drilling. It features a drill point tip (similar to a twist drill bit) and a threaded shank, making it ideal for joining thin metal sheets, steel structures, or composite materials.

Key Features:

Material: Typically made from carbon steel (ST/SC) or stainless steel (A2/A4), with optional coatings like zinc plating, galvanization, or phosphating for corrosion resistance.

Head Styles: Countersunk head (flat head, 90° angle) as per DIN 7504 standard, ensuring a flush finish.

Thread Types: Partial or full thread options for varied grip strength.

Point Types: Type N (standard drill point) or Type H (enhanced performance for thicker/harder materials).

Drive Types: Cross recess (Phillips/Pozi) or hexagonal socket (internal drive).

Applications:

Sheet metal assemblies (e.g., HVAC, roofing).

Steel framing, automotive, and electrical enclosures.

Lightweight construction with aluminum or plastics.

Standards:

Complies with DIN 7504 (German industrial standard) for dimensions and performance. Equivalent to ISO 15480.

Advantages:

Eliminates pre-drilling, saving time and labor.

High shear strength and vibration resistance.

Corrosion-resistant variants available for harsh environments.
