S-90657A113 M4 x 16 mm DIN 920 Steel Cheese Head Slotted Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding environments
• High tensile strength of 60,000 psi ensures reliable load-bearing capacity for industrial applications
• Rockwell B71 hardness provides excellent wear resistance and durability under mechanical stress
• Class 6g thread fit guarantees precise, secure mating with nuts and threaded components
• Slotted drive design allows for quick installation and removal with standard tools
• Partially threaded shank enables optimal clamping force and prevents loosening in dynamic assemblies
• DIN 920 compliance ensures dimensional accuracy and interchangeability in metric systems

Professional Applications & Engineering Value

This M4 x 0.7 mm zinc-plated steel rounded head screw delivers exceptional performance in industrial settings where vibration resistance and long-term reliability are critical. The coarse thread pitch and Class 6g tolerance facilitate rapid assembly while maintaining secure fastening in machinery, electrical enclosures, and automotive components. The cheese head profile with slotted drive offers a low-profile solution for space-constrained applications, while the zinc plating protects against oxidation and chemical exposure. Its partial threading concentrates clamping force precisely where needed, reducing the risk of joint failure in high-stress environments.

Specification Summary & Compliance

This screw adheres to DIN 920 specifications with M4 x 0.7 mm coarse thread and Class 6g thread fit for metric applications. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material traceability. The 16 mm length and flat tip design support standardized installation processes across industrial sectors.
