Specialty Micrometers
Available33 products
Specialty micrometers are used for specific jobs like measuring the inside and outside dimensions of tube thickness, gear teeth, pitch diameter of fasteners, and for measuring sheet metal thickness. Specialty micrometers have standard vernier or digital displays, but the size, shape, and orientation of the jaw, spindle, and anvil vary.
Range
Spherical Face Micrometers
Spherical face micrometers, also known as round or rounded face micrometers, have a standard outside micrometer body, thimble, and C-shaped jaw. Both contact faces are rounded, and they are commonly used to take measurements of rounded features.

Adjustable-Collar & Interchangeable-Anvil Outside Micrometers
Interchangeable anvil outside micrometers have a standard micrometer C-shaped jaw and stock, but have anvils that can be changed to accommodate a range of applications. These micrometers are commonly used in machine shops, automotive repair shops, and for applications requiring a single micrometer with a range greater than 1”. Similarly, adjustable-collar micrometers are outside micrometers with an extension anvil collar and included setting standards to accomodate variable measuring lengths within a given range larger than a standard outside micrometer.

Disc Micrometers
Disc micrometers measure the thickness of work sections like ribs, lands, fins, cutting edges on form tools, and the thickness of gear teeth. With their large anvil and spindle faces, they are also used for measuring thin sheets of materials like paper, cardboard, rubber, and plastics.

Sheet Metal Micrometers
Sheet metal micrometers, also called deep jaw micrometers, take thickness measurements of sheet metal, paper, plastic, and rubber parts. These micrometers have a standard stock with thimble actuation, but have a deep, narrow jaw with a flat measuring face that is paired with a round or flat anvil.

Point Micrometers
These point micrometers resemble standard micrometers with C-shaped jaws, stock, and thimble but the measuring faces on the spindle and anvil come to sharp points. These smaller and pointed contact points are used to measure small grooves, recesses, and other tight spaces on a workpiece where a standard micrometer can’t be used. They are also used for making quick comparisons of thread accuracy in screw cutting applications.

Blade Micrometers
Blade micrometers have non-rotating spindles with flat blades for contact points. They have a standard micrometer body, thimble, and C-shaped jaw. They take accurate measurements of circular form tools, diameter and depth readings of narrow grooves, slots, keyways, recesses, and depths between lands and fins.

Crimp Height Micrometers
Crimp height micrometers have a standard micrometer body and jaw with specialized measuring faces that are used to determine the height of crimp contacts. The anvil is used to support and position the top of the crimp while the pointed spindle is adjusted until it contacts the bottom of the radial surface. They are commonly used for measuring electrical components and plastic parts.

Tube Micrometers
Tube micrometers take thickness measurements of wall tubing and are used for measuring from a hole to an edge. These micrometers have a flat spindle paired with a cylindrical anvil that extends perpendicular to the spindle for a slim, rounded face used for the inside of small rounded features.

Multi-Anvil Micrometers
Multi-anvil micrometers are built with a unique jaw to take measurements that are not possible with standard micrometers. They are commonly used for measuring the wall thickness of tubing, cylindrical walls, and the thickness of screw heads.

Screw Thread Micrometers
Screw thread micrometers have a standard stock with adjustable thimble actuation, but have a jaw with a cylindrical spindle that comes to a point with a double V-shaped anvil. This specialty micrometer allows users to accurately measure the pitch diameter of a screw.

Spline Micrometers
These spline micrometers take measurements of splined shafts, slots, and keyways. They have a standard jaw and body design, but are built with small-diameter cylindrical measuring faces. They have a thimble that adjusts the faces so they contact the features being measured.

Ball Anvil Micrometers
Ball anvil micrometers have a standard micrometer body, thimble, C-shaped jaw, and flat spherical spindle, but are built with a rounded ball anvil for measuring rounded features. The rounded anvil is used to contact the inside curved surface of a feature while the flat spindle is used for contacting the outside to produce a single point of contact. These micrometers are commonly used to measure the wall thickness of parts like solid and split bearings, tubing, sleeves, collars, rings, various cylinders, and for measuring from the inside of a hole to an edge.
