The Insize 4139-15P Fine Thread Plug Gage is a precision inspection tool engineered for accurate verification of internal thread dimensions. Conforming to ISO 1502 standards, this plug gauge is designed for M15 × 1 metric fine threads and includes both “Go” and “No-Go” ends — making it ideal for quality control, production, and maintenance applications. Its hardened, ground construction ensures long-term durability, repeatable accuracy, and reliable performance under frequent use.

  • Model: 4139-15P
  • Thread size: M15 × 1 (metric fine thread)
  • Tolerance class: 6H (internal thread tolerance) 
  • Type: Go / No-Go Plug Gauge (dual-end)

Why Choose the 4139-15P Plug Gage?

  • Fast and reliable thread verification: Instantly confirms whether internal threads meet required specifications — essential during machining, tapping, or final inspection.
  • Dual-end Go / No-Go design: “Go” end checks that the thread is cut to correct pitch and depth; “No-Go” end ensures that threads are not oversized — preventing out-of-tolerance parts from passing inspection.
  • Production-ready durability: Hardened, ground steel construction withstands repeated insertion without loss of accuracy, ideal for shop floors and inspection workbenches.
  • Standards compliance: Built to ISO 1502, making it compatible with global quality requirements for metric fine threads.
  • Simplicity & speed: A compact, manual gauge that requires no power — perfect for on–the–spot checks or use in a tool room, maintenance bay, or production line.

Whether you’re performing quality control, thread inspection, or verifying threaded components before assembly, the 4139-15P plug gage provides a precise, trusted, and efficient solution — an essential tool in any machinist’s or inspector’s toolkit.
