I do have a set. Just don't wanna waste money on another having the same ones. I know it's either t50, t55 or t60. I believe it's t55, but need confirmation. There are no info anywhere.
According to Toyota’s Repair Manual (available by subscription to techinfo.toyota.com), it’s a T50 TORX, for both 2016 and 2017 models. The seat bolts are supposed to be torqued to 37 N•m, in this order: front inside, front outside, rear inside, rear outside. Rather than a TORX key, the Repair Manual recommends a TORX socket, which can be used with a torque wrench. The seat’s attachment to the body may be important for its performance in a collision, so I’d want to be careful that the bolts are tightened to the specified value.
Hi Deathmage - what size worked for you, please? Need to yank front seats on 2016 Prius Two. Tried the T-40 but was too small. thx
On my 2016, it’s definitely a T50, just as the Repair Manual says. I haven’t removed mine, either, so I can’t say what they do in manufacturing. The Repair Manual doesn’t mention the need to apply a thread coating or to use only new (and perhaps pre-coated) bolts, which it does for other fasteners that are non-reusable or require an adhesive. The torque specification (see post #4) is printed inside a double box, which Toyota uses to emphasize the “Tightening torque for ‘Major areas involving basic vehicle performance such as moving/turning/stopping.’”
