Starrett Telescopic Bore Gauge Set Steel 6 Piece Maximum 152mm Minimum 8mm S579HZ

Starrett S579HZ Telescopic Bore Gauge Set is a professional 6 piece steel gauge set designed for precise internal measurements of holes and slots within the range of 8mm to a maximum of 152mm. The set includes six distinct gauges covering ranges 8-13mm, 13-19mm, 19-32mm, 32-54mm, 54-89mm, and 89-150mm, equipping users to measure a wide variety of internal diameters accurately.

Each telescopic gauge features a rigid knurled steel handle that provides firm handling, complemented by a knurled contact locking screw to securely fix measurements. The contact points are precision ground to a radius that offers adequate clearance for small hole entries and ensures measurement accuracy.

The internal mechanism includes constant spring tension to deliver uniform contact pressure against measured surfaces, guaranteeing data reliability. The gauge size is read by measuring across the contact points using calibrated instruments such as vernier calipers or micrometers.

This set is highly suited for industrial applications including automotive repair and manufacturing, machining operations, fabrication workshops, and quality assurance laboratories requiring precise internal dimension checks.

The gauges cover internal diameter ranges from 8mm up to 152mm for versatility in measurement. Constructed from robust steel, the Gauges offer durability and long-term reliability. The knurled handles and screws enhance handling precision and operational ergonomics.

Precision-ground contact points and spring tension impart consistent and accurate measurement pressure. Ideal for automotive, machining, fabrication, manufacturing, and workshop environments.

Starrett is a globally recognized brand in measuring instruments, and this telescopic bore gauge set upholds their reputation for quality and accuracy. This set is essential for professionals seeking precise internal measurement tools for industrial or laboratory use.
