Key Features & Benefits at a Glance
- Exceptional tensile strength of 110,000 psi ensures reliable performance under high-stress conditions, reducing the risk of fastener failure in demanding applications.
- Superior corrosion resistance from zinc plating extends service life and maintains integrity in harsh or outdoor industrial environments.
- High hardness rating (Rockwell C21) provides excellent wear resistance and durability, minimizing deformation during installation and use.
- Coarse thread design with 2 mm pitch allows for quicker assembly and better grip in a variety of materials, enhancing efficiency on the production line.
- Partially threaded shank offers optimal clamping force distribution, preventing loosening in dynamic or vibrating machinery.
- Precise Class 6h thread fit ensures consistent engagement and alignment, reducing the chance of cross-threading and improving assembly reliability.
- External hex drive and hex head facilitate easy installation with standard tools, speeding up maintenance and reducing labor time.
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this M14 hex head screw combines Class 8.8 steel construction with a zinc-plated finish to address common challenges like corrosion, vibration-induced loosening, and high tensile stress. The partially threaded design and coarse metric thread provide secure fastening in structural assemblies, machinery frames, and automotive components, where consistent clamp load and resistance to dynamic forces are critical. By meeting ISO 4014 and DIN 931 standards, it ensures interoperability and reliability, reducing downtime and maintenance costs in sectors such as manufacturing, construction, and equipment repair.
Specification Summary & Compliance
This fastener features an M14 x 2 mm coarse thread with Class 6h thread fit for precise dimensional accuracy, and a length of 80 mm with a minimum thread length of 34 mm. It conforms to ISO 4014, DIN 931, and ISO 898 specifications for mechanical properties, and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe and sustainable use in global markets.
