the tubing 180 e g a threaded connection and the hanging shoulder 112 are sufficient to bear the weight of the hanger string along which the hanger is placed the weight of such hanger string imposes shear and bearing forces on latches 132 and collet 130 may be designed and manufactured to withstand such shear and bearing forces however the fingers of collet 130 generally do not bear any such load in some embodiments it may be possible to include latches 132 of one material and attach them to a collet of another weaker material because in such embodiments the fingers may only function to connect the piston 160 to latches 132 and to push the latches 132 up the angular surface 122 cone 120 when the piston 160 is actuated the embodiment of fig1 a is shown as having a collet 130 with latches 132 having a smaller outer radius in the relaxed state than in the set state illustrated in fig2 a embodiments having a collet with latches 132 at a larger radius in the relaxed state than in the set state are also within the scope of the present disclosure in some wells host tubing 210 may extend from the well surface in a single diameter to the engagement section 220 in such wells retracting the collet 130 for insertion into the well may permit the inner surface 214 of the host tubing 210.
