Jeu de boulons à tête extensible by FEL-PRO - ES71129-1

Fel-Pro T-T-Y head bolts have been designed to stretch within a defined yield zone. It springs back to give an accurate tightening force once it reaches a specific zone. T-T-Y head bolts cause the bolts to push into their elastic range. In rare circumstances, the stretching reaches the elastic limit of the bolts, causing them to stretch permanently. Reusing stretched T-T-Y head bolts may result in incorrect or unequal torque, damaged engine threads, and broken bolts, any of which can cause head gasket failure. It is necessary to use new bolts during reassembly and follow precise torquing methods. Fel-Pro gaskets provide 100 per cent vehicle sealing with application-specific materials, giving consumers sealing choices that specialists rely upon performance and reliability.
