Quality Spring Calipers- Measuring Engineering Workshop Hand TOOLSom (6"/ 150 MM - Inside Caliper)

• Professional Internal Measurement: Specifically designed for high-accuracy measurement of internal diameters (ID), this 6-inch (150 mm) Inside Caliper is the perfect tool for gauging holes, bores, and hollow workpieces.
• High-Quality Tool Steel: Manufactured from premium-grade hardened and tempered tool steel, this caliper is built to withstand industrial wear and tear while maintaining its precise shape for years of service.
• Zero-Play Bow Spring Mechanism: Featuring hardened bow springs and heavy-duty fulcrum spools, the mechanism ensures uniform tension with zero "play" or looseness. This provides the stability required for consistent, reliable readings.
• Quick & Positive Adjustment: Equipped with a precision adjusting screw, self-seating washer, and nut. This mechanism allows for rapid adjustments that remain positively locked in place while transferring measurements.
• Forged Steel Legs for Enhanced Accuracy: The legs are forged for maximum structural integrity, and the contact points are specially hardened. This ensures a sensitive "feel" and superior accuracy when navigating internal surfaces.
• Versatile Layout Tool: An excellent instrument for capturing dimensions from uneven surfaces or complex internal curves. It remains the preferred choice for machinists and woodworkers for tracing contours and internal layout work.
• Accurate Transfer with Rulers: For the most precise results, this tool is designed to be used alongside precision steel rules. It is the most dependable manual method for verifying and transferring unknown internal dimensions.
• Trusted ASSORTS Craftsmanship: Manufactured by Assorts Machine Tools, this professional-grade caliper delivers consistently reliable performance for lathe work, boring operations, and general engineering applications.
