Key Features & Benefits at a Glance
- Exceptional durability with Rockwell C38 hardness and 180,000 psi tensile strength for reliable performance in high-stress environments
- Corrosion-resistant black-oxide coating on alloy steel extends service life and maintains integrity in harsh conditions
- M8 coarse thread with 1.25mm pitch ensures quick assembly and secure fastening, reducing installation time
- Integrated 15mm flange distributes load evenly, eliminating the need for separate washers and simplifying assembly
- Precision Class 4h thread fit provides consistent engagement and vibration resistance for long-term stability
- External 12-point drive with 10mm size allows for high-torque application and easy access in confined spaces
- Partially threaded 30mm design offers optimal grip and clamping force where full threading isn't required
Professional Applications & Engineering Value
This M8 12-point flange screw delivers critical engineering solutions where vibration resistance and structural integrity are paramount. The black-oxide alloy steel construction combined with 180,000 psi tensile strength makes it ideal for heavy-duty automotive assemblies, industrial machinery, and equipment subjected to dynamic loads. The coarse metric thread (1.25mm pitch) prevents cross-threading during rapid assembly, while the 15mm flange diameter provides superior bearing surface, reducing point stress and preventing loosening under constant vibration. The external 12-point drive enables high-torque installation with standard tools, ensuring reliable fastening in space-constrained applications where traditional hex drives might fail.
Specification Summary & Compliance
This metric 12-point screw features precise M8 x 1.25mm coarse threading with Class 4h thread fit for consistent dimensional accuracy. The partially threaded design provides 22mm minimum thread length on a 30mm overall length, with 15mm flange diameter and 10mm external 12-point drive. Manufactured from alloy steel with black-oxide surface treatment, it meets standard industrial specifications and is compliant with RoHS and REACH environmental directives for safe usage across various sectors.
