S-97478A188 M27 x 160 mm DIN 6914, ISO 7412 Metric High-Strength Steel Heavy Hex Head Screws for Structural Applications

Key Features & Benefits at a Glance

• Exceptional tensile strength of 150,000 psi ensures reliable performance in demanding applications, reducing the risk of fastener failure.
• Superior corrosion resistance from hot-dipped galvanized steel coating extends service life in harsh environments, minimizing maintenance needs.
• High hardness rating (Rockwell C32) provides excellent wear resistance and durability under heavy loads.
• Coarse thread pitch (3mm) enables faster installation and better grip in various materials, improving assembly efficiency.
• Class 6g thread fit ensures precise threading compatibility, reducing cross-threading issues and enhancing connection reliability.
• Partially threaded design allows for optimal clamping force distribution, ideal for applications requiring specific grip lengths.
• Compliance with DIN 6914/ISO 7412 standards guarantees consistent quality and interchangeability in industrial settings.

Professional Applications & Engineering Value

This M27 hex head screw delivers critical engineering value in heavy-duty applications where structural integrity is paramount. The hot-dipped galvanized steel construction provides robust protection against corrosion, making it suitable for outdoor construction, infrastructure projects, and industrial machinery exposed to moisture or chemicals. With its Class 10.9 strength grade and metric coarse thread, it offers superior clamping force and vibration resistance, addressing common challenges like joint loosening in dynamic loads. The external hex drive facilitates easy installation with standard tools, while the partially threaded configuration ensures precise load-bearing contact. Engineers specify this fastener for steel frame assemblies, bridge components, and equipment bases where high tensile strength and long-term reliability are non-negotiable.
