Key Features & Benefits at a Glance
- Exceptional tensile strength of 170,000 psi ensures reliable performance under extreme loads, reducing the risk of fastener failure in critical applications.
- Superior corrosion resistance from the black-oxide finish on alloy steel, extending service life in harsh industrial environments.
- High hardness rating (Rockwell C37) provides excellent wear resistance, maintaining thread integrity through repeated use.
- Precision Class 5g6g thread fit guarantees smooth assembly and secure fastening, minimizing play and vibration loosening.
- Standard hex drive (17mm) allows for easy installation with common tools, speeding up maintenance and reducing labor time.
- Fully threaded design offers consistent clamping force along the entire 40mm length, ideal for applications requiring uniform pressure distribution.
- Compliance with DIN 912/ISO 4762 ensures dimensional accuracy and interchangeability, supporting global engineering standards.
Professional Applications & Engineering Value
This M22 socket head cap screw is engineered from black-oxide alloy steel to address common industrial challenges such as corrosion, high stress, and assembly efficiency. The Class 12.9 strength rating and coarse 2.5mm pitch metric thread provide robust fastening in heavy machinery, automotive systems, and structural frameworks, where vibration resistance and durability are paramount. The fully threaded right-hand design ensures maximum grip in thick materials, while the standardized 33mm head diameter and 17mm hex drive facilitate quick installation with standard wrenches, reducing downtime. Ideal for demanding environments, this screw delivers reliable performance in applications requiring high tensile strength and compliance with international specifications.
Specification Summary & Compliance
