Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance in high-stress applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the black-oxide finish on alloy steel extends service life in harsh industrial environments.
- High hardness rating (Rockwell C37) provides excellent wear resistance, maintaining thread integrity through repeated use.
- Precise Class 5g6g thread fit offers consistent engagement and vibration resistance in assembled components.
- Standard hex socket drive (4 mm) allows for easy installation with common tools, minimizing assembly time and effort.
- Partially threaded design combines strong clamping force with unthreaded shank stability for secure fastening.
- Compliance with DIN 912/ISO 4762 standards guarantees dimensional accuracy and interchangeability in global engineering projects.
Professional Applications & Engineering Value
This Class 12.9 socket head cap screw is engineered for demanding applications where high tensile strength and durability are critical. The black-oxide alloy steel construction provides enhanced corrosion resistance, making it ideal for machinery, automotive assemblies, and heavy equipment exposed to moisture or chemicals. With coarse M5 x 0.8 mm threads and a partially threaded rod, it ensures rapid installation and secure clamping in metal-to-metal joints, reducing loosening from vibrations. The hex socket drive facilitates tight spaces access, while adherence to DIN 912/ISO 4762 standards ensures reliable performance in precision engineering and manufacturing sectors, minimizing downtime and maintenance costs.
Specification Summary & Compliance
This metric screw features M5 x 0.8 mm coarse right-hand threads with a Class 5g6g thread fit for precise tolerance, a minimum thread length of 22 mm, and overall length of 70 mm. It conforms to DIN 912/ISO 4762 specifications for dimensional accuracy and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and suitability for industrial use.
