Starrett S579HZ

Product Highlights

• Starrett telescoping gages are 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
• These tools 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slightly "rocked" in the hole being measured to ensure that the tool is on the proper diameter before it is locked and withdrawn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
• The No. 579 Series is similar to the No. 229 Series except that is has a slightly greater range, and the handles are rigidly attached to the contact plungers and are automatically self-centering
• Also, the No. 579 gages have two telescoping contacts
