WebRBE (Rigid Body Element) Bolt: Line element represents the stud while rigid links are used to model the head and nut. 4. Spider Bolt: Line elements are used to simulate the stud, head, and nut sections of the fastener. 5. Hybrid Bolt: Head and nut section of the bolt is modeled as a solid while the stud section is modeled with a line element. WebCan you work out the yield strength of this bolt – M16-4.6/S? If you got 240 MPa, you’d be correct. That’s a mild steel bolt. We use these on handrails and holding down bolts in concrete but not much else. Bolts are also tightened to a specification: (S) – Being ‘snug’ (TF) – Friction type application (TB) – Bearing type application
