Description

The VCOIL Plug Gauge (D/E) is a precise UNF (STI) thread gauge designed to verify Helicoil inserts and related components to ANSI/ASME standards. It combines go and no-go functionality in a compact, right-hand gauge, built for reliable shop-floor checking.

  • Thread system: UNF (STI) compatibility for accurate assessment of fine-thread inserts.
  • Go/No-Go plug gauge: Integrated go and no-go ends to confirm both success and scrap criteria in one tool.
  • Scrap-side marking: Red ring clearly identifies the scrap side for quick pass/fail decisions.
  • Orientation: Right-hand gauge design to match standard right-hand thread applications.
  • Tolerance class: 2B tolerance control for consistent measurement and quality results.
  • Size designation: 1 x 12 for clear sizing reference in your gauge inventory.
  • Standards reference: Aligned with ANSI/ASME thread standards for compliant measurements.
  • Reference temperature: Measurements standardized at 20°C to ensure consistency across parts and gauges.

Designed to streamline quality control, the VCOIL Plug Gauge helps you quickly confirm that threads meet the required tolerances without forcing parts. It reduces guesswork during assembly, supports consistent insert performance, and provides a reliable go/no-go evaluation on every check, making it an essential tool for machinists, quality inspectors, and maintenance teams.
