S-97595A486 M4 x 6 mm DIN 7991 Brass Hex Drive Flat Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance from high-quality brass construction, ideal for harsh industrial environments
• Precise Class 6g thread fit ensures reliable fastening and vibration resistance in demanding applications
• High tensile strength (70,000 psi) provides exceptional load-bearing capacity for structural integrity
• Rockwell B55 hardness offers excellent durability and resistance to wear during installation and use
• 2.5mm hex drive design enables secure tool engagement and prevents stripping during high-torque applications
• 90° countersink angle with standard flat head profile creates flush surface finishes for aesthetic and safety requirements
• Full threading along 6mm length delivers maximum grip strength and uniform stress distribution

Professional Applications & Engineering Value

This M4 brass flat head screw with hex drive addresses critical engineering challenges in industrial assembly where corrosion resistance and reliable fastening are paramount. The Class 6g thread fit according to DIN 7991 standard ensures consistent performance in vibration-prone equipment, while the coarse 0.7mm pitch facilitates quicker installation in production environments. The combination of Rockwell B55 hardness and 70,000 psi tensile strength makes these metric screws suitable for electrical enclosures, machinery components, and marine applications where brass's natural anti-galling properties prevent seizing. The fully threaded design with right-hand direction provides complete engagement in thin materials, solving common pull-out failures in sheet metal and plastic assemblies.

Specification Summary & Compliance

Manufactured to DIN 7991 specifications with Class 6g thread tolerance for precision metric threading. The M4 x 0.7mm coarse thread with 6mm length, 8mm head diameter, and 2.3mm head height maintains dimensional accuracy. Compliant with RoHS 3 (2015/863/EU) under exemption 6(a)-I for lead as alloying element and REACH (EC 1907/2006) regulations, ensuring environmental responsibility in industrial supply chains.
