Description / Abstract:
This SAE Metric Aerospace Standard (MA) provides dimensional,
performance, testing and other requirements for high strength, thin
wall, double head box and combination wrenches which possess an
internal wrenching design so configured that, when mated with
hexagon (6 point) fasteners, they shall transmit torque to the
fastener without bearing on the apex of the fastener's wrenching
points. This standard provides additional requirements beyond ANSI
B107.9 appropriate for aerospace use.
