S-98093A534 M8 x 16 mm ISO 898-1, DIN 6921 High-Strength Metric Class 10.9 Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with black-phosphate steel coating, ideal for harsh industrial environments
• High tensile strength of 150,000 psi and Class 10.9 rating for reliable performance in demanding applications
• Flanged hex head design provides increased bearing surface and eliminates the need for separate washers
• Fully threaded coarse pitch (M8 x 1.25mm) ensures faster assembly and superior vibration resistance
• Precision Class 6g thread fit guarantees consistent engagement and optimal clamping force
• External hex drive compatibility allows for standard tooling and efficient installation
• Rockwell C32 hardness maintains structural integrity under heavy mechanical stress

Professional Applications & Engineering Value

These M8 hex head screws with Class 10.9 strength rating and black-phosphate coating address critical engineering challenges in heavy machinery, automotive assemblies, and structural frameworks. The fully threaded coarse pitch design (1.25mm) prevents loosening under vibration while enabling rapid installation in high-volume production environments. With 150,000 psi tensile strength and flanged head construction, they distribute clamping forces evenly across joined surfaces, reducing point stress and preventing material deformation. The external hex drive accommodates standard industrial tools, streamlining maintenance and assembly processes where corrosion resistance and mechanical reliability are paramount.

Specification Summary & Compliance

Manufactured to ISO 898-1 and DIN 6921 specifications with Class 6g thread tolerance for precision fit. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features metric coarse threading (M8 x 1.25mm), 16mm length, and 18mm flange diameter for consistent performance across industrial applications.
