Four-Way Versatile Measurement: Accurately measures external dimensions, internal bore diameters, hole depths, and stepped surfaces using a single mechanical tool.
0.05mm Precision Vernier Resolution: Fine micro-graduated vernier scale delivers 0.05mm resolution for high-accuracy engineering inspection and metal fabrication verification.
Hardened Carbon Steel Construction: Robust carbon steel body and ground measuring jaws resist dimensional wear, burring, and deflection under continuous mechanical use.
Dual-Scale Metric & Imperial Markings: Laser-etched, wear-resistant graduations feature millimeter and inch conversions on the main beam and vernier plate for fast, error-free reading.
Locking Screw & Smooth Slider: Top-mounted knurled thumb lock screw secures the sliding jaw at any position to freeze dimensions for repetitive tolerance checking across Nepal.
