S-94036A216 M6 x 16 mm ISO 898-1, DIN 6921 Medium-Strength Metric Class 8.8 Steel Flanged Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc yellow-chromate plating, extending service life in harsh industrial environments
• High tensile strength of 110,000 psi and Class 8.8 grade ensures reliable performance under heavy loads and vibration
• Integrated flange design eliminates the need for separate washers, simplifying assembly and reducing component count
• Precision Class 6g thread fit with coarse 1mm pitch enables faster installation and secure fastening in various materials
• Partially threaded shank provides optimal clamping force distribution and prevents thread damage during tightening
• External hex drive with 10mm head offers excellent torque transmission and compatibility with standard tools
• Rockwell C22 hardness maintains thread integrity and prevents stripping during repeated use

Professional Applications & Engineering Value

These M6 hex head screws deliver critical engineering solutions where vibration resistance and structural integrity are paramount. The zinc yellow-chromate plated steel construction provides exceptional protection against oxidation and chemical exposure, making them ideal for outdoor equipment, automotive assemblies, and industrial machinery. The flanged design distributes clamping pressure over a wider surface area (14.2mm diameter), preventing surface damage to softer materials while the partially threaded configuration ensures precise load-bearing capability. With coarse thread spacing and Class 6g thread fit, these metric fasteners offer rapid installation in steel frameworks, aluminum extrusions, and composite materials, reducing assembly time while maintaining Class 8.8 strength requirements for structural applications.

Specification Summary & Compliance

Manufactured to exact ISO 898-1 DIN 6921 specifications with Class 6g thread tolerance ensuring dimensional accuracy. The 16mm length with 13mm minimum thread length provides consistent engagement depth. Fully compliant with REACH regulations (EC 1907/2006) regarding substance restrictions, making them suitable for regulated industries and international supply chains.
