Product Description

Weatherproof Hex Head Self-Drilling Fasteners

Zinc Plated with EPDM Sealing Washer

Product Overview

These high-performance industrial fasteners feature a hexagonal washer head and specialized drill point, manufactured to DIN 7504K standard from Grade 410 stainless steel. Engineered to drill their own pilot hole, tap mating threads, and provide secure fastening in a single operation, these screws offer superior performance for metal-to-metal applications.

Core Features

Exceptional Hardness: Grade 410 stainless steel can be hardened through heat treatment, allowing penetration of carbon steel sheets and harder substrates without tip burnout
Time-Saving Efficiency: Integrated drill point eliminates pre-drilling and hole alignment, reducing installation time and labor costs
Corrosion Resistance: Provides reliable protection against atmospheric corrosion, water, and mild chemicals
High Torque Strength: Hexagonal head design ensures maximum torque transmission and prevents cam-out during high-speed installation
Integrated Sealing: Compatible with EPDM bonded washers for leak-proof sealing in outdoor and roofing applications

Application Scenarios

Steel Construction & Metal Framing: Fastening metal sheets to steel purlins or sub-structures in industrial buildings
Roofing & Cladding: Installation of metal roof panels and wall cladding systems requiring weather resistance and structural integrity
HVAC Systems: Securing ductwork and mounting equipment components in heating and cooling systems
Automotive & Machinery: Assembly line applications requiring high-speed fastening into metal frames
Solar Energy Systems: Mounting solar panel brackets to aluminum or steel support rails

Packaging Options

Carton 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.

Outer Carton Box Packaging

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.

Pallet Packaging

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.
