Our Grade 12.9 High-Strength Nickel-Plated Hex Socket Socket Head Cap Screws with Elastic & Flat Washer Set are engineered for reliability in demanding industrial applications. Each assembly includes a precision-machined screw, a spring washer (elastic pad), and a flat washer, pre-assembled for convenience and guaranteed performance.

 

Crafted from Premium Carbon Steel with a Grade 12.9 rating, these screws deliver exceptional tensile strength and hardness, far exceeding standard fasteners. The nickel-plated finish offers superior corrosion and rust resistance, ensuring longevity in harsh environments, moisture-rich conditions, and outdoor installations.

 

Designed for Secure Installation featuring a hex socket (inner hexagon) drive, these screws allow for precise torque application with a hex key, reducing cam-out and stripping. The integrated spring washer provides critical anti-loosening protection by absorbing vibration, while the flat washer distributes pressure evenly to prevent surface damage and ensure a stable fit.

 

Versatile & Dependable Available in a range of sizes to suit diverse needs, these 3-in-1 fastener sets are ideal for industrial machinery assembly, automotive parts manufacturing, precision equipment installation, aerospace, construction, and heavy-duty mechanical applications.
