Authorized Insize distributor  |  Ships direct from Insize  |  Quote reply same day

Reference standards for setting and checking your measuring tools: individual steel gage blocks and sets in grades 0, AS-1 and AS-2 to ASME B89.1.9, angle gage blocks, plus and minus pin gage sets such as 4162-1161, setting rings, micrometer setting standards and steel and ceramic balls.

Choosing between options

If you need to…ChooseExample

Check a large outside micrometerMicrometer setting standard6311-6

Before you order

  • Gage block grade sets the tolerance: grade 0 is tighter than AS-1, and AS-2 is looser (ASME B89.1.9).
  • Setting rings are marked with their actual size, which can differ slightly from the nominal size ordered.
  • Ships direct from Insize. Most items are in stock; we confirm your ship date by email after you order.
