  • Sealed Box with Quantity Labels: Pre-sorted in a sealed organizer with quantity labels printed inside each compartment. Instantly identify sizes, prevent loss or mix-ups, and keep your workspace tidy. Compact 5.2 x 3.6 x 0.6 in case fits toolbox, drawer or glove box.
  • Versatile + Risk-Free: Perfect for furniture assembly, automotive repair, machinery manufacturing, construction, bicycles and DIY. Use a torque or socket wrench and avoid impact wrenches. Backed by responsive after-sales support — contact us if anything falls short.
