The draper outside spring callipers are precision measuring instruments designed for accurately gauging external dimensions in engineering, metalworking and general workshop applications. These traditional spring callipers feature fine ground construction that ensures consistent accuracy when measuring cylindrical objects, shaft diameters and external workpiece dimensions. The knurled adjustment wheel provides smooth, controlled calibration, allowing for precise incremental adjustments during measurement tasks. This fine-tuning mechanism is particularly useful when working to tight tolerances or when transferring measurements to other tools or workpieces. With a 150mm capacity, these outside spring callipers are ideal for a wide range of workshop tasks including lathe work, quality control checks and component inspection. The spring calliper design offers excellent tactile feedback, making them a reliable choice for tradespeople who value traditional measuring methods alongside digital alternatives. Features and benefits: fine ground construction for consistent measurement accuracy knurled adjustment wheel for precise, controlled calibration 150mm capacity suitable for general workshop measuring tasks contents: 1 x outside spring calipers, 150mm
