Product Description and Features:

The advantages of stainless steel 410 with EPDM gasket for stainless steel drill tail screws are:
1, Strong penetrability.

Although the penetration of 410 stainless steel drill tail screws is inferior to that of carbon steel screws, it is significantly better than that of 304 stainless steel screws.
It is mainly suitable for direct fixation of steel structures and color steel tile houses, and can penetrate steel plates with a thickness of 2.5-5mm without pre drilling. It is commonly used in outdoor scenes such as building roof installation that require rapid construction.
‌
2, Good anti rust performance.
410 stainless steel drill tail screws have better rust prevention performance than galvanized carbon steel screws, and the composite gasket they come with can effectively seal and prevent liquid leakage. They are particularly suitable for connecting industrial equipment in humid environments or with corrosive media, such as the construction of roofs in Southeast Asian or coastal residential buildings with high rainfall and humidity;
It can also be used in the connection of various chemical equipment.

3, 410 stainless steel has magnetism, making it easy to install.

Due to the magnetic properties of 410 stainless steel, it can be quickly positioned and installed using magnetic suction tools, greatly improving construction efficiency.

Packaging:

Carton Packaging	Outer Cartonbox Packaging	Pallet Packaging
Bolts are packed in neutral packaging boxes, with standard quantities arranged in small cartons. The exact number of units per carton will be confirmed with the customer to align with their specific requirements. Customized packaging configurations are available upon request.	The small cartons are then consolidated into larger master cartons for secure transportation and storage. The quantity per master carton can be customized based on client specifications or aligned with standard logistical requirements.	The palletized units are securely wrapped with waterproof film and reinforced with packaging straps. Customer-specific shipping marks or labels are affixed to each pallet, ensuring clear identification and compliance with logistics requirements. This final packaging stage guarantees weather-resistant protection and stability during transportation.
