• Full-thread design maximizing grip length and distribution for enhanced fastening security across the entire 20mm length

Professional Applications & Engineering Value

This M6 brass flat head screw delivers exceptional engineering value through its optimized material properties and DIN 7991 certification. The brass construction provides inherent corrosion resistance critical for electrical components, marine hardware, and plumbing systems where moisture exposure is common. The 1mm coarse pitch threading combined with Class 6g thread fit ensures rapid installation while maintaining vibration resistance in machinery assembly. The flat head profile with 90° countersink creates seamless surface finishes in predrilled applications, eliminating protrusions that could interfere with moving parts. With 70,000 psi tensile strength and Rockwell B55 hardness, these industrial brass fasteners withstand substantial mechanical stress while the 4mm hex drive prevents tool slippage during high-torque applications. The fully threaded 20mm length maximizes contact surface for superior holding power in wood, plastic, and soft metal substrates.
