S-90386A105 M6 x 35 mm DIN 6921 Medium-Strength Metric Class 8.8 Steel Serrated-Flange Hex Head Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with zinc-plated steel construction, extending service life in harsh industrial environments
• Superior tensile strength of 110,000 psi ensures reliable performance in high-stress applications without failure
• Secure anti-loosening grip from the serrated locking flange, preventing vibration-induced loosening in machinery
• Easy installation and removal with external hex drive design, compatible with standard tools for efficient assembly
• Precise thread fit (Class 6g) guarantees smooth engagement and consistent clamping force in metric assemblies
• Full threading along the 35 mm length provides maximum grip and load distribution across the entire fastener
• Compliance with DIN 6921 and environmental standards ensures quality, safety, and regulatory adherence for global projects

Professional Applications & Engineering Value

These M6 hex head screws are engineered to address critical challenges in industrial fastening, such as vibration resistance and corrosion protection. The zinc-plated steel material offers a durable barrier against moisture and chemicals, reducing maintenance costs in automotive, machinery, and construction applications. The serrated locking flange eliminates the need for additional washers by providing a firm bite into surfaces, preventing rotation under dynamic loads. With a coarse thread (M6x1 mm) and Class 6g thread fit, these screws ensure quick, reliable installation in metal frameworks and equipment, while the fully threaded design maximizes holding power in high-tensile scenarios. Ideal for heavy-duty metric fasteners, they deliver consistent performance where precision and durability are paramount.

Specification Summary & Compliance

This fastener adheres to precise dimensional standards, including Class 6g thread fit for metric applications and full compliance with DIN 6921 for flanged hex head screws. It meets regulatory requirements such as RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring environmental safety. The manufacturing specifications cover a tensile strength of 110,000 psi, Rockwell C22 hardness, and right-hand coarse threading, supporting reliable use in industrial assemblies.
