Product Description: This is an 8-piece metric M10x1.50 exhaust manifold / flange stud set, consisting of 8 studs. The thread pitch of the stud is M10x1.50. The overall length of the stud is approximately 71mm. The threaded portions of the stud measure approximately 32mm and 20mm. These studs are premium quality and high strength. These pieces were acquired from a General Motors Assembly Plant but work for many other manufacturers.

E Torx sockets and fasteners can apply more torque than regular hex or bi-hex sockets without damaging the fastener head. This is because of the greater contact area between the socket and the fastener head, along with the fact that more of the torque is applied away from the corners of the fastener head, so there is less chance of it rounding off.
