Design Resistance for TW Type Blind Bolts |  | ||||
| TW Bolt Size | Set Screw Diameter (mm) | Collar Outside Diameter (mm) | Hole Diameter (mm) | Shear Resistance (kN) | Tension Resistance (kN) |
| TW5 | 5 | 7.8 | 8 | 13.2 | 4.8 |
| TW6 | 6 | 9.5 | 10 | 19.5 | 14.1 |
| TW8 | 8 | 12.6 | 13 | 34.5 | 25.6 |
Design resistances in shear and tension are presented above. The resistance values may be compared directly with the ultimate loads applied to the fixing.
The bearing resistance may be calculated in accordance with the design standard, based on the external diameter of the collar, as given above.
Fixings subject to combined shear and tension should be verified in accordance with the design standard, using the design resistances presented above.
If tension is applied to a fixing in a relatively thin wall application, the deformation of the connected material should be considered at serviceability (working loads) and at the ultimate limit state, as deformation is likely to be the limiting feature of the connection.
