S-93070A105 M4 x 16 mm DIN 7984 Alloy Steel Low-Profile Socket Head Screws

Key Features & Benefits at a Glance

• Superior strength for demanding applications - Class 8.8 alloy steel construction provides a high tensile strength of 110,000 psi, ensuring reliable performance under heavy loads and vibration.
• Space-saving low-profile design - The reduced head height allows for installation in tight or recessed spaces where standard socket heads cannot fit.
• Precise and secure fastening - A Class 6g thread fit ensures smooth installation and a secure hold, minimizing the risk of loosening in dynamic environments.
• Excellent wear and corrosion resistance - The Rockwell C20 hardness offers enhanced durability and longevity, reducing replacement frequency and maintenance costs.
• Optimized for high-torque applications - The 2.5 mm hex drive and socket head design provide a positive grip, preventing tool slippage and allowing for higher installation torque.
• Broad industrial compatibility - The coarse M4 x 0.7 mm thread and fully threaded shank enable quick assembly and are ideal for a wide range of materials and components.
• Guaranteed quality and safety compliance - Manufactured to DIN 7984 standards and compliant with RoHS 3 and REACH, ensuring material safety and environmental responsibility.

Professional Applications & Engineering Value

This M4 socket head cap screw is engineered to solve critical challenges in precision machinery, automation systems, and heavy-duty equipment assembly. The Class 8.8 alloy steel provides the necessary high tensile strength to withstand sustained operational stresses, while the low profile socket head is crucial for applications with limited clearance, such as in compact enclosures or on machined surfaces. The fully threaded design with a coarse thread pitch ensures maximum grip and pull-out resistance in softer materials or when used with metric threaded inserts. Its Rockwell C20 hardness and Class 6g thread fit guarantee consistent performance and ease of installation, reducing assembly time and preventing thread galling, making it a reliable industrial fastener for engineers and OEMs.

Specification Summary & Compliance

This screw features precise M4 x 0.7 mm coarse threads with a Class 6g tolerance for consistent fit.
