How can I check if the embedding or surface bonding of a bigHead will resist the screw tightening torque?
15 May 2026
Adhesives and embedment interfaces primarily transfer clamp load and service loads into the parent structure. Testing the rotational loading resistance of the fastener installation is not the same as determining its capability to resist torque-tightening during assembly.
You should base any evaluation of torque-tightening resistance on assembly trials with system representative specimens, not torque-off or torque-out testing of rotational-loading specimens.
