Compact precision for on-the-go work

Meet the Olsa Tools Bolt Size Finder Keychain, a pocket-ready gauge designed to help you identify bolt heads quickly. It covers Metric 8-25 mm and SAE 5/16-1 in, letting you pick the right socket without trial fittings.

On the go, this little tool shines: it attaches to your keyring, so you’ll have it whenever you need it—no fumbling through a toolbox. Its dual-sided design lets you switch between Metric and SAE without hunting for the right side, saving time during a busy day.

Benefits at a glance:

  • Dual-sided metric and SAE measurements for fast cross-referencing
  • Pocket-friendly design that travels with your keys and tools
  • Time-saving sizing, reducing guesswork and back-and-forth trips to the toolbox

Beyond bolts, this handy gauge offers quick estimates of thread sizes, hose fittings, and other small components, helping you verify compatibility before you source a part. It’s well suited for routine sizing during assemblies, repairs, and parts catalog checks, and it makes a thoughtful gift for mechanics and DIY enthusiasts alike.
