Key features

• Complete Sae & Metric Kit: Includes 75 precision thread checker: 39 Blue SAE and 36 Red Metric thread checkers, covering a wide range of coarse and fine threads for both male and female fasteners
• Precision and Durable Thread Gauges: CNC-machined aluminum construction resists wear; SAE meets ANSI B1.1 2A/2B, Metric complies with ISO 68-1 6G/6H; laser-engraved markings stay clear for accurate Go/No-Go checks every time
