Key Features & Benefits at a Glance
- Exceptional durability with Class 10.9 tensile strength (120,000 PSI) and Rockwell C32 hardness, ensuring reliable performance in high-stress environments.
- Superior corrosion resistance from the black-oxide coating on alloy steel, extending service life in harsh industrial conditions.
- Efficient installation and removal with a 10 mm hex drive and standard flat head profile, reducing assembly time and tool wear.
- Secure fastening in coarse materials due to the M16 coarse thread (2 mm pitch) and Class 6g fit, minimizing loosening under vibration.
- Versatile full-thread design for consistent grip along the entire 120 mm length, ideal for varying material thicknesses.
- Precise flush mounting enabled by the 90° countersink angle, providing a smooth surface finish in countersunk applications.
- Compliance with international standards including DIN 7991 and ISO 10642, ensuring quality and interoperability in global projects.
