Metric Bolt & Screw Measurement Gauge

The Metric Bolt & Screw Measurement Gauge is an essential workshop reference tool designed for the rapid identification and sortation of metric fasteners. Engineered to streamline organization in automotive workshops and garages, it allows technicians to instantly determine both thread size and shank length without guesswork.

The durable gauge measures metric thread diameters ranging from M3 up to M12, alongside fastener lengths from 4mm to 120mm in precise 2mm increments.

Why Choose a Metric Bolt & Screw Gauge?

A dedicated fastener measurement tool is essential for:

• Quickly identifying loose, mixed, or unlabeled bolts from workshop sorting trays
• Matching correct replacement thread sizes (M3 to M12) before starting repairs
• Measuring exact fastener lengths from 4mm to 120mm in 2mm increments to prevent bottoming out
• Keeping service benches organized and eliminating trial-and-error fitting

Unlike rulers or thread pitch gauges alone, this dedicated measurement plate combines thread sizing holes and length scales into a single, straightforward reference board.
