Proto® 9 Piece Fractional Black Chrome Non-Reversible Combination Ratcheting Wrench Set – Spline JSCR-9S

  • 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 was created for use with specialty spline bolts which are used when weight and size of bolt heads must be minimized
  • 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)
  • The high contact surface area which is away from fastener points enables turning of highly rounded fasteners
  • Anti-Slip Design (ASD) open end
  • Fractional spline wrenches can be used on fractional 4, 6, 12 point, spline and Torx® fasteners
  • Includes: 1/4″, 5/16″, 3/8″, 7/16″, 1/2″, 9/16″, 5/8″, 11/16″, 3/4″ wrenches with pouch
