WELD ANGLE GAUGE: 60,70,80,90 DEG DASQUA

* This Dasqua screw pitch gauge has metric & whitworth leaves Total amount of leaves = 57

* Made of alloy steel precision ground * Blades marked with thread size * Packed in plastic pouch When referring to thread pitch gauges, "Unified" indicates that the tool is designed to measure threads conforming to the Unified Thread Standard (UTS), which is the dominant inch-based screw thread standard used in the United States, Canada, and the United Kingdom. Here is a breakdown of what this means in the context of gauging: Standardized Geometry: Unified gauges are designed with a 60° thread angle, which is the profile standard for UTS (UNC, UNF, UNEF) and makes them compatible with imperial fasteners.
