Part Name: Hex (Allen) Wrench 0.05″

Part Description: A hex (or Allen) wrench (or key) is an L-shaped tool that has a hexagonal cross-section and is used for tightening and loosening fasteners with complimentary hexagonal sockets in their heads. Hex wrenches come in an L-shape so that either end can be used depending on whether you need to reach into tight spaces with the long end or you need to generate more torque with the short end.
