Key Features & Benefits at a Glance
- Exceptional tensile strength of 110,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Corrosion-resistant zinc-plated steel provides enhanced durability and longevity, even in demanding industrial environments.
- Integrated flange design eliminates the need for a separate washer, simplifying assembly and providing a larger bearing surface for improved load distribution.
- Class 8.8 strength grade guarantees consistent mechanical properties, offering dependable fastening for critical connections.
- Coarse 1 mm thread pitch allows for quicker installation and better resistance to vibration loosening compared to fine threads.
- Full threading along the 30 mm length ensures maximum grip and adjustability in a variety of material thicknesses.
- Compliance with DIN 6921 and environmental regulations (RoHS 3 & REACH) assures quality, safety, and suitability for regulated industries.
Professional Applications & Engineering Value
Engineered for robustness, these M6 hex head screws are crafted from zinc-plated steel to combat corrosion in harsh settings like machinery assembly, automotive frameworks, and structural steelwork. The external hex drive and coarse metric thread with a 1 mm pitch enable rapid, secure fastening, minimizing installation time while resisting vibration-induced slack. The flanged design distributes clamping force evenly, preventing surface damage and enhancing joint integrity. With a Rockwell C22 hardness and Class 8.8 strength, they address common industrial challenges such as load fatigue and mechanical stress, making them ideal for heavy-duty applications where reliability is paramount.
Specification Summary & Compliance
This screw features precise M6 x 1 mm coarse threads with a Class 6g thread fit for consistent engagement, adhering to DIN 6921 manufacturing standards. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for industrial use.
