Best-in-class Telescoping Gauges to Measure up to 6-inch Holes and Bores. The top American manufacturer of tools and instruments, Starrett presents a whole collection of telescoping gauges and gauge sets with greater ranges to enable the precision measuring of inside dimensions of bores, recesses, etc. The models offered by the company are self-centering varieties with two telescoping arms. The measuring ranges of the different models are 5/16 - 1/2, 1/2 - 3/4, 3/4 - 1-1/4, 1-1/4 - 2-1/8, 2-1/8 - 3-1/2, and 3-1/2 - 6 inches. The 579-series telescoping gauges from Starrett have a glossy satin-chrome finish. The ends of both arms of the gauges are precision-ground and hardened to form a radius edge that provides you with excellent clearance even in the smallest hole. Before you lock the tool in the hole to be measured, you need to lightly shake it in the hole to make sure that the gauge is on the actual diameter of the hole. With this done, you are good to go to receive results with maximum accuracy. You can use these snap gauges for measuring the exact size of recesses, grooves, slots, holes, etc. of up to 6 inches. The constant spring tension offered by the gauges gives you uniform contact pressure while measuring. You can effortlessly lock the telescoping arms at any required setting. Moreover, the arms self-center automatically. Under the spring tension, the arms expand from the center to the precise size of the hole, and then, you can lock them there by the knurled knob. Then, you can measure the size with a micrometer or a caliper. Offered with two double-action plunging telescopic rods, these snap gauges are the best to help you with measuring to tenths and thousandths. You can order the telescoping gauges individually or in sets. The available gauge sets from Starrett are S229FZ (3 pieces), S579GZ (4 pieces), S229GZ (5 pieces), and S579HZ (6 pieces).
