{"product_id":"gf-gage-g551856-10-32-unf-2b-sti-double-end-thread-plug-gage","title":"GF Gage G551856 #10-32 UNF 2B STI Double-End Thread Plug Gage","description":"\u003cdiv style=\"font-family:Arial,sans-serif;line-height:1.6;color:#333;max-width:800px;\"\u003e\n\u003cp\u003eThis is a new GF Gage G551856 (order\/serial ref 55315816) double-end (DE) thread plug gage for #10-32 UNF internal threads to Class 2B tolerance, configured for STI (Screw Thread Insert \/ HeliCoil) oversize threads. The GO member is engraved \"10-32 UNF STI GO PD .2103\" and the NO-GO (NOT-GO) member is visible on the opposite end, both machined to W-tolerance (Class X) working gage limits per ASME B1.2. The STI designation means the gage checks the tapped hole that will receive a wire-thread insert (e.g., HeliCoil), which requires a larger pitch diameter than a standard 10-32 hole; the GO PD of .2103 in confirms the STI oversize. The gage ships in a clear plastic case with a GF Gage Certificate of Compliance dated 2\/27\/2025, traceable to NIST masters inspected in a 68°F temperature-controlled laboratory per MIL-STD-45662A, making it suitable for AS9100, ISO 9001, and defense manufacturing inspection requirements.\u003c\/p\u003e\n\u003ch3
