A4-80 Stainless Steel Socket Cap Screws DIN 912 | Duchy Fasteners

These premium A4-80 socket cap screws are engineered for demanding applications where strength, precision, and corrosion resistance are essential. Manufactured from high-grade 316 stainless steel, they deliver outstanding durability and reliability, even in harsh and corrosive environments.

Conforming to DIN 912 standards, each screw features a precisely machined hexagonal socket head, allowing secure installation with a hex key and excellent torque transmission. The high tensile strength of A4-80 stainless steel makes these fasteners ideal for mechanical, structural, and heavy-duty fastening where safety and long-term performance are critical.

Designed for use across a wide range of industries, these stainless steel socket cap screws are well suited to:

Construction and structural assemblies
Industrial and engineering projects
Marine and offshore environments
Mechanical, automotive, and high-performance machinery

The superior corrosion resistance of 316 stainless steel provides excellent protection against rust, chemicals, saltwater, and extreme weather, ensuring a long-lasting, low-maintenance fastening solution. This makes them particularly effective in outdoor, marine, and chemically exposed installations where standard steel fasteners would quickly degrade.

Available in a range of metric dimensions, these socket cap screws offer precise, secure fastening for everything from compact assemblies to large structural connections. Whether you are working on industrial equipment, marine hardware, or precision engineering projects, they provide a strong, clean, and professional finish.

Choose A4-80 316 stainless steel socket cap screws to ensure high-strength performance, secure clamping, and exceptional resistance to corrosion in the most challenging environments.
