Proto Stanley 8-Piece Double Box Racheting Spline Wrench Set

The Proto JSBV-8S 8 Piece Black Chrome Reversible Ratchet Wrench Set is specifically designed for servicing high tensile strength fasteners commonly found on military and commercial aircraft, heavy machinery, automotive, and industrial applications where vibrations are prominent. These wrenches are essential for achieving high performance torque requirements.

The unique Spline profile of these tools allows for a higher torque to be applied without the risk of rounding off the fastener corners. By distributing the applied loads away from the corners, the spline wrench can effectively turn already worn or rounded fasteners. The set includes 8 different wrench sizes: 7/32" x 9/32", 1/4" x 5/16", 3/8" x 7/16", 1/2" x 9/16", 5/8" x 11/16", 3/4" x 7/8", 13/16" x 15/16", 1" x 1-1/8", all stored neatly in a tool roll for easy organization.

Featuring a black chrome finish, these wrenches are not only visually distinctive but also corrosion resistant. The ratcheting spline box end is countersunk for quick and efficient application to the fasteners. The precision fit between the fastening tool and fastener helps reduce foreign object debris (FOD) during use. These fractional spline wrenches are versatile and can be used on fractional 4, 6, 12 point, and spline fasteners.

Imported for quality and reliability, the Proto JSBV-8S 8 Piece Black Chrome Reversible Ratchet Wrench Set is a must-have for any professional or DIY enthusiast working with a variety of fasteners.
