Proto Long Arm Hex Key - 7/64" J46207-SBD

Proto's professional-grade individual L-key engineered for industrial maintenance and precision mechanical tasks. It features an extra-long arm design (3-21/32") that provides the extended reach needed for deeply recessed fasteners and increased leverage for high-torque applications. Manufactured from heat-treated alloy steel and finished with a black oxide coating, this tool is built to resist rotational deformation and environmental corrosion. This 7/64" size is a critical component for various machinery set screws and specialized mechanical assemblies.
