The washers are held in position with the key diameter with the thread currently being larger than the opening with the washer. This is accomplished by inserting the washers in advance of thread rolling.
Torx Screws would not have camout issues as no camout forces are established to thrust the motive force up and out of the fastener recess.
Be aware: When correcting softer resources to metallic, consider using a simple washer under the head to stop the head from digging into the delicate material.
They provide a protected signing up for, and stay clear of fastener reduction or injury Which may be attributable to a free element.
