Stainless steel drilling screws use scenarios and advantages

Stainless steel self-drilling screws (Self-Drilling Screws) are a kind of efficient fasteners that integrate drilling, tapping and fastening functions, showing significant advantages in many fields. The following are its main usage scenarios and core advantages:

1. Typical usage scenarios
Construction industry

Installation of light steel structure (color steel plate, sun room, curtain wall)

Fixing of roof waterproofing membrane

Assembly of ventilation ducts and cable trays

Industrial manufacturing

Connection of sheet metal parts of mechanical equipment (control cabinet, chassis)

Installation of automobile/ship interior parts

Assembly of metal shelves and storage cages

Home decoration

Fixing of aluminum alloy doors and windows

Connection of wood-plastic board/composite board with metal keel

Installation of outdoor fence and anti-theft net

Special environment

Chemical equipment (corrosion resistance requirements)

Buildings in coastal high salt fog areas

Low-temperature outdoor facilities (such as cold storage)

2. Core advantages
Efficient construction

Self-drilling and self-tapping: The tip drill tail design can directly penetrate thin steel plate (≤6mm) or aluminum alloy, eliminating the pre-drilling step and increasing the installation efficiency by more than 50%.

One-time forming: The thread and the drill bit complete the tapping and tightening simultaneously to avoid secondary operations.

Super weather resistance

Material advantages: 304/316 stainless steel is corrosion-resistant, has passed the salt spray test for more than 1,000 hours, and has a service life of 3-5 times that of ordinary carbon steel screws.

Surface treatment: optional passivation or plating (such as Geomet®) to further extend the service life.

Reliable connection

High torque design: cross slot or hexagonal head provides greater tightening force and resists vibration loosening.

Thread optimization: double-line thread or high and low tooth design to improve bite force (especially suitable for thin plate connection).

Economical

Low overall cost: save drilling tools, labor and time costs.

Less maintenance: no regular anti-rust treatment is required, reducing long-term maintenance costs.

Wide adaptability

Complete specifications: diameter range (Φ2.5-Φ6.5mm) and length (10-150mm) are optional.

Various head shapes: pan head, countersunk head, hexagonal flange head meet the sealing or load-bearing requirements of different scenarios.
