Outside - Jaw Micrometers

4 products

Our Outside Jaw Micrometers are tailored for measuring larger or irregularly shaped components with ease. Extended jaw designs provide better grip and access to difficult-to-reach surfaces, ensuring precise readings without distortion. These micrometers are favored in heavy industry, fabrication shops, and precision engineering facilities where accuracy across diverse workpieces is required. Built with hardened measuring surfaces and ergonomic design, they combine durability with ease of use.

Frequently Asked Questions

An outside jaw micrometer is a precision tool specifically designed to measure the external dimensions of objects, such as thickness, diameter, or length. HK Calibrations provides high-quality models that offer sub-millimetre accuracy, ensuring your engineering and manufacturing projects meet strict Australian tolerance standards.

To maintain precision, you should regularly clean the measuring faces and check the zero point using a setting standard before each use. HK Calibrations recommends professional NMI-traceable calibration at least once a year to verify that the internal screw mechanism and jaw alignment haven't drifted.

A ratchet stop or friction thimble ensures that a consistent amount of pressure is applied to the object being measured, which prevents over-tightening. This feature, found on instruments from HK Calibrations, eliminates operator variability and ensures repeatable, highly accurate measurements across different users.

Digital micrometers offer faster reading times and the ability to switch between metric and imperial units, which reduces human error during data recording. HK Calibrations supplies both types, though digital models are often preferred in modern Australian workshops for their clear LCD displays and data output capabilities.

Many of our professional micrometers are built with IP65-rated protection, making them resistant to dust, coolant, and oil splashes commonly found in machine shops. HK Calibrations ensures these tools are durable enough to maintain their high-precision performance even in demanding industrial conditions.

The most reliable outside jaw micrometers feature carbide-tipped measuring faces to provide maximum resistance against wear and abrasion over time. By sourcing your equipment from HK Calibrations, you ensure that the measuring surfaces stay flat and parallel, which is critical for long-term measurement integrity.
