General sizing procedures Roller screws provide shock-load resistance and handle loads up to 779,000 lbf. These conditions apply also to crankshafts in which the parts are clamped or taper fitted; constructions which involve the need for riveting (i. 4 Elastic Torque-Tension Relationship A practical starting point for all threaded fastener tightening analysis is to use the basic elastic torque-tension equation, T = K*D*F, to estimate the relative magnitudes of torque and clamp force. Unwin's formula gives a relation between hole diameter of rivet and thickness of the connected plates. rivets and/or spring-loaded fasteners to minimize material creep and eliminate sheet gap. ) Because the alternating load is small, so is the alternating stress, usually well below the bolt's endurance limit.
