Proto Long Arm Hex Key - 1/8" J46208-SBD

Proto's professional-grade individual hex key designed for industrial maintenance and mechanical assembly. This tool features an extra-long arm design (3-29/32"), which provides significantly better access to deeply recessed fasteners and increased leverage for high-torque applications compared to standard keys. It is manufactured from high-strength alloy steel and finished with a black oxide coating for superior resistance to rotational torque and environmental corrosion. This 1/8" size is a versatile requirement for a wide range of machinery, automotive components, and industrial equipment.
