WebHI-LITE™ pin (HST) HI-LITE™ pins are the direct evolution of HI-LOK™ pins. These fasteners can be used for clearance, or low interference fit throughout aircraft, from wings to fuselage, in engine fairings, and more. … WebThe grade classification of a bolt is indicative of the strength of the material of the bolt. The two grades of bolts commonly used are grades 4.6 and 8.8. For a 4.6 grade 4 indicates that the ultimate tensile strength of the bolt = 4 × 100 = 400 N/mm 2 and 0.6 indicates that the yield strength of the bolt is 0.6 × ultimate strength = 0.6 × ...

Web21 Sep 2024 · HSFG (High Strength Friction Grip) bolts are usually made from medium carbon steel and have a higher tensile strength than the ordinary black bolt, as well as improved vibration and impact resistance. Bolts of class 8.8 and 10.9 are commonly used. HSFG bolts with induced initial tension are called high-strength friction grip bolts or HSFG … WebSecond tightening step is done by specified part turn. To calculate torque value, km figure for assembly classified as a k-Class K1 is required. For simplification, use km = 0.125 can be used (as per EN 1090-2:2024, pt. 8.5.2 a.1.), however we strongly recommend using provided km figure that been evaluated through testing. thinking does not play well on television
