Starrett 196B5 Universal Back Plunger Dial Test Indicator 0-50-0 0.001" Graduation

The Starrett 196B5 Universal Back Plunger Dial Indicator is one of the most versatile and trusted precision measuring instruments available. Featuring a balanced 0-50-0 dial reading and a 0.200" measurement range, this indicator delivers accurate, reliable results for the vast majority of measurement and inspection tasks encountered in machining, manufacturing, and quality control environments.

The back plunger design allows the indicator to be positioned in tight spaces and used where a standard front-plunger indicator cannot reach. The 1-1/2" white-face dial with scratch-resistant crystal face provides excellent readability, while jeweled bearings ensure smooth, precise operation. Graduations of 0.001" with 0.1" per revolution allow the operator to quickly detect and quantify surface variation with confidence.

Key Features:

• Balanced 0-50-0 dial reading with 0.001" graduations
• 0.200" total measurement range (0.1" per revolution)
• 1-1/2" white-face dial with scratch-resistant crystal
• Jeweled bearings for smooth, precise movement
• Universal back plunger style for versatile mounting
• 1/4" (6.3mm) diameter stainless steel shank
• Satin chrome finish for durability and corrosion resistance
• Knurled bezel for easy zero-setting
• Includes 3 hardened contact points (1/2", 5/16", and 1/8" diameter) and adapter
• Certificate of Inspection included
• Made in the USA

How to Use: Select the appropriate contact point from the three included hardened contacts, then bring it against the workpiece with enough pressure to advance the hand one full revolution. Rotate the knurled bezel to set the hand at zero. The indicator will then display both rise and drop from that reference point, showing the amount of surface variation across the full 0-50-0 range.

The Starrett 196 series has earned its reputation as the benchmark back plunger dial indicator since its introduction, combining rugged construction, minimal moving parts, and proven accuracy. It is ideal for quality control inspection of machined parts, shaft alignment, setup work, and general precision measurement in industrial and shop environments.
