FAQ

What does property class 8.8 signify for these LOBO bolts?

Property class 8.8 indicates a high-tensile steel bolt. The first ‘8’ means the nominal ultimate tensile strength is 800 MPa, and the second ‘8’ means the yield strength is 80% of the ultimate tensile strength (640 MPa). This makes them suitable for high-stress applications.

Are these DIN 912 bolts interchangeable with ISO 4762?

Yes, for most practical purposes, DIN 912 and ISO 4762 are interchangeable standards for hexagon socket head cap screws. While there might be minor historical differences in tolerances, ISO 4762 is the current international standard that has largely replaced the German DIN 912.

What is the recommended tightening torque for an M20 grade 8.8 bolt?

The recommended tightening torque can vary based on the lubrication and application. However, for a standard, dry (unlubricated) M20 grade 8.8 bolt, a typical tightening torque is approximately 466 Newton-meters (Nm). Always consult your specific engineering guidelines.
