Proto Wrench Box, Ratcheting Double, 1/4'' X 5/16''AF Straight, Spline Rev, Steel Black, 4.1/2''L SBV0810

• The chrome-vanadium switch lever allows for easy changes in turning direction which helps improve efficiency.
• Ratcheting spline box end is chamfered for easy application to the fastener.
• 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 also helps prevent rounding of corners and other fastener damage that could lead to Foreign Object Damage (FOD).
• Spline wrenches can be used on fractional 4, 6, 12 point and spline fasteners.
