Product Details
229 Series™ 1/2 to 2-1/8" SAE and Metric Telescoping Gauge Set by Starrett®. The Starrett Telescoping Gage is used for determining the true size of holes, slots, and recesses up to 6" (150mm). The ends of both contacts are hardened and ground to a radius to allow proper clearance on the smallest hole the gage will enter. This tool must be slightly rocked in the hole being measured to ensure that the tool is on the proper diameter before it is locked and withdrawn. The final hole size is obtained by measuring over the gage contacts with a micrometer. SET, Includes 3, Nos. 229A/B/C in Case.
