The Proto PRO4990-8MXL is an extra-long hex bit socket designed for industrial and professional use. Featuring a 3/8" drive and an 8mm hex bit, its 6-3/32" overall length provides the extended reach needed to access deep or recessed fasteners in tight spaces.
Built to Proto Industrial standards, this hex bit socket is ideal for MRO, automotive, and heavy-duty assembly applications where standard-length sockets fall short. The extra-long design reduces the need for extensions while maintaining secure torque transfer.
