The rod measures 6 inches (150 mm) overall length with a 1\/8 in (0.0125 in \/ ~3.175 mm) diameter hardened steel rod; the satin chrome finish reduces glare and resists corrosion during precision inspection. A knurled locking collar (visible in images) secures the rod at the desired extension, and the ball-end tip — clearly shown in multiple photos — contacts the groove floor for accurate depth transfer to the mated 440 gage. The part number encodes: \"30-959\" = groove checker rod family for the 440 series; \"1\" = straight (non-offset) rod configuration; \"50\" = 50 mm \/ approximately 2 in usable depth range. Supplied in a protective clear plastic storage tube as shown, and manufactured in the USA.\u003c\/p\u003e\n\u003ch3
