Starrett 70803 Tapered Contact Point 4-48 Agd Dial Indicators

Product Description

The STARRETT 70803 is a tapered contact point replacement accessory designed for use with AGD dial indicators. Machined from steel, this contact point features a 4-48 thread for secure attachment and a tapered tip geometry that allows accurate measurements in restricted or hard-to-reach areas. The contact point measures 3/16 inches in length with a tip diameter of 1/16 inches and an overall length of 1/4 inch. It is a precision component intended for machinists, quality control technicians, and tool and die professionals who rely on dial indicator accuracy for part inspection and alignment work.

This contact point is suited for precision measurement applications in machine shops, manufacturing facilities, and quality inspection environments. The tapered style is commonly used when standard ball-tip contact points cannot seat properly against a workpiece surface. It threads directly onto AGD-standard dial indicators, making it a straightforward field replacement when a contact point becomes worn or damaged. The compact size allows use in tight inspection setups where clearance is limited.

Key Features

• Tapered contact point style for restricted-access measurement applications
• Steel construction for durability and wear resistance
• 4-48 thread size for compatibility with AGD dial indicator stems
• 3/16 inches contact point length with 1/16 inches tip diameter
• Overall length of 1/4 inch for compact fitment
• Sold individually as a single replacement unit

Compatibility

Designed for use with AGD dial indicators that accept a 4-48 threaded contact point stem.

Installation Notes

Installation is performed by threading the contact point onto the dial indicator stem by hand until snug. Avoid over-tightening, which can damage the fine 4-48 threads on either the contact point or the indicator spindle. Ensure the indicator is removed from service and not under spring load before swapping contact points. A small flat wrench or contact point wrench is recommended for final seating to prevent cross-threading.
