M5 A4-80 Stainless Hex Set Screws DIN 933

Product Description

M5 A4-80 Stainless Steel Fully Threaded Hexagon Set Screws – DIN 933

These M5 fully threaded hexagon set screws are manufactured from high-strength A4-80 stainless steel. Often described as marine-grade stainless, A4 provides improved resistance to corrosion and chloride-containing environments compared with A2 stainless steel.

Property class A4-80 provides a minimum tensile strength of 800 N/mm² (800 MPa). The fully threaded design makes these fasteners suitable for clamping components where maximum thread engagement or adjustable grip is required.

• Food-processing and clean-production equipment
• Chemical-processing installations
• Automotive and engineering assemblies
• Applications requiring corrosion resistance and high tensile strength

For best corrosion performance, use these fasteners with compatible M5 × 0.8 A4 stainless steel nuts and washers. Stainless fasteners can be susceptible to thread galling, so a suitable anti-seize compound may be beneficial during assembly. Tightening torque should be determined from the joint design and operating conditions.
