America's most popular specialty outside micrometers


Starrett T436RLS-3 1/2 Automotive Crankshaft Micrometer

This large outside micrometer is designed for automotive work and especially for crankshaft measuring. It is also well suited for all other work within its capacity. It measures the diameter of the journal bearing and main bearing of most crankshafts since the micrometer has a range from 1-1/2"-3-1/2". The reading point is on the under side of the sleeve (not on the side as in regular micrometers), plainly visible while measuring. It's a very useful feature when measuring between webs. Combination ratchet and speeder for uniform pressure and quicker adjustment. Gracefully designed tapered frame for use in narrow slots and tight places. Rigid one-piece frame of drop forged steel, ribbed for extra strength. Extremely hard and stable one-piece spindle. Micro-lapped steel measuring faces. Quick and easy sleeve adjustment.
