Item #: 11842-JSCV16F

Product Info


  • 15 deg angled offset helps keep shank clear of obstructions
  • Chrome vanadium box ends and switch levers provide high strength and durability
  • 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 applies force over a larger area, reducing risk of fastener scoring and helps prevent rounding of the corners and other fasteners 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
  • Black chrome finish is corrosion-resistant and visually distinctive
  • 72-teeth ratcheting mechanism rotates fast with only 5 deg of swing
