Product Description

Carbon Steel Roofing Screws: Hex Socket Self-Drilling Fasteners with EPDM Gaskets

Product Overview

These DIN 7504K self-drilling screws are high-performance industrial fasteners featuring hexagonal washer heads and specialized drill points. Manufactured from Grade 410 stainless steel, these screws drill their own pilot holes, tap mating threads, and provide secure fastening in a single operation. Grade 410 martensitic stainless steel can be heat-treated for enhanced hardness, making it superior to 304 or 316 grades for metal-to-metal applications.

Core Features

Exceptional Hardness: Heat-treatable 410 grade steel penetrates 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: Reliable protection against atmospheric corrosion, water, and mild chemicals in humid environments
High Torque Strength: Hexagonal head design ensures maximum torque transmission and prevents cam-out during power tool installation
Integrated Sealing: Compatible with EPDM bonded washers for leak-proof seals in outdoor and roofing applications

Application Scenarios

Steel construction and metal framing for industrial buildings
Roofing and cladding systems requiring weather resistance and structural integrity
HVAC systems for securing ductwork and mounting equipment components
Automotive and machinery assembly lines with high-speed fastening requirements
Solar energy systems for mounting panel brackets to aluminum or steel support rails
