Proto® 9 Piece Ratcheting Spline Wrench Set

• Black chrome finish is corrosion resistant and visually distinctive
• Non-reversing ratcheting wrenches can be flipped over to turn the fastener in the opposite direction
• Ratcheting spline box end is countersunk for easy application to the fastener
• Spline design also helps prevent rounding of corners and other fastener damage that could lead to Foreign Object Damage (FOD)
• Spline design enables the wrench to contact conventional fasteners away from the corners, which help apply force over a large area helping to reduce risk of fastener rounding
• Spline design was created for use with specialty spline bolts which are used when weight and size of bolt heads must be minimized
