Niigata Seiki Thread Pin Gauge, M4 x P0.7, made in Japan.
• Makes centering internally threaded holes easy.
• Using two gauges together also lets you measure the pitch between hole centers.
• Can be attached and removed quickly with simple tools.
• Allows datum setting from a threaded hole, which was previously difficult.
• Cheaper, faster, and more accurate than earlier methods.
• Stainless steel resists rust, and the tapered section provides high-precision support.
