Product Description

Zinc Plated Carbon Steel Hex Washer Head Self-Drilling Screws with EPDM Washers

Product Overview

Zinc Plated Carbon Steel Hex Washer Head Self-Drilling Screws with EPDM Washers conform to DIN7504K standard. These high-performance industrial fasteners feature a hexagonal washer head and specialized drill point, engineered to drill pilot holes, tap mating threads, and provide secure fastening in a single operation.

Core Features

Exceptional Hardness: Heat-treated 410 grade stainless steel provides superior penetration capability for carbon steel sheets and harder substrates
Time-Saving Efficiency: Integrated drill point eliminates pre-drilling requirements, 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: EPDM bonded washers provide leak-proof seals for outdoor and roofing applications

Application Scenarios

Steel Construction & Metal Framing: Fastening metal sheets to steel purlins in industrial buildings
Roofing & Cladding: Installation of metal roof panels and wall cladding systems requiring weather resistance
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
