Our Plastic Dial Calipers offer precision measurements at affordable prices, making them a great choice for hobbyists and do-it-yourselfers. This metric-reading caliper features a no-glare dial for accurate readings of inside, outside, depth and step measurements up to 0.1mm. The slide is easily advanced and retracted with a free-wheeling thumb roller, and the 6” bar scale is marked with 1/16” and 10mm graduations.
