RUKO SCE-DIN223-M2x0.4mm Thread Plug Gauge GO/NO-GO Metric ISO 6H

In precision engineering, verifying internal thread accuracy is critical to ensure component interchangeability and reliable assembly. The RUKO SCE-DIN223-M2x0.4mm thread plug gauge provides a definitive GO/NO-GO inspection solution for M2 x 0.4 mm metric ISO internal threads, conforming to DIN 223 and ISO 1502 standards.

Who is it for

Quality control technicians, machinists, and manufacturing engineers who need to validate tapped holes in production or incoming inspection. Ideal for workshops producing or checking components with fine metric threads.

Main features

• Double-ended GO/NO-GO design for quick pass/fail assessment.
• GO side checks maximum material condition; NO-GO side checks minimum material condition.
• Thread form: Metric ISO thread with 60° profile angle, tolerance class 6H.
• Precision ground and lapped from high-grade gauge steel, hardened and stress-relieved for durability.
• Cylindrical knurled handle for secure grip and easy identification.
