DIN 912 A4 Stainless Socket Head Cap Screw Sizes Guide
DIN 912 A4 Stainless Socket Head Cap Screw Sizes Guide
DIN 912 A4 stainless socket head cap screws are high-strength metric fasteners designed for use in demanding environments where corrosion resistance is essential. These screws feature a cylindrical head and internal hex drive, making them ideal for machinery, marine equipment, engineering assemblies and outdoor installations.
Manufactured from A4 stainless steel (also known as marine grade stainless steel), these fasteners provide excellent resistance to corrosion, saltwater and harsh environments. Because of this, A4 socket head cap screws are commonly used in marine applications, coastal environments, food processing equipment and chemical industries.
What Are DIN 912 A4 Socket Head Cap Screws?
DIN 912 is the international standard that defines the dimensions and specifications of socket head cap screws. These screws are recognised by their:
• Cylindrical head
• Internal hex (Allen) drive
• High tensile strength
• Precision metric threading
The internal hex drive allows high torque to be applied using an Allen key, making DIN 912 screws ideal for applications where space is limited or where a clean, flush installation is required.
