Proto Long Arm Hex Key - 7/32" J46214-SBD

Proto's professional-grade individual L-key designed for industrial maintenance and high-torque mechanical assembly. Featuring an extra-long arm configuration (4-13/16"), this tool provides the extended reach necessary to access deeply recessed fasteners and offers superior leverage compared to standard-length keys. It is manufactured from heat-treated alloy steel and finished with a black oxide coating to ensure the tool resists both rotational deformation and environmental corrosion. This 7/32" size is a standard requirement for various heavy-duty machinery and industrial equipment.
