TORQUE / ANGLE TOOLS

These are the torque-angle wrenches used and recommended for this reference. Standalone angle adapters can also work; no specific budget adapter is being endorsed here.

Sequence graphics are redrawn for clarity. Torque values and special fastener notes remain in live page text so they can be verified and updated independently of the artwork.
