Locating Pins

Carr Lane’s floating locating pins provide precise location in one particular axis while allowing considerable float in the correlating perpendicular axis. Typically used along with a Round Pin to locate two machined holes in a workpiece or to align two fixture components without causing binding.  Chamfered tip especially manufactured for easy part loading. These pins are function in a manner similar to Diamond Pins, except they allow greater variation in hole spacing. Floating locating pins are available in pin diameters 1/4, 5/16, 3/8, 1/2, and 5/8".

These precision locating pins feature a chamfered tip for effortless part loading and a shoulder that helps resist downward forces. Typically, one Round Pin and one Diamond Pin are used together to locate two machined holes in a workpiece or to align two fixture components without causing binding.  The head and shank diameters of the round locating pins are concentric to within .0005" TIR. These pins are available with head diameters ranging from 1/4" to 1" (6 to 20mm in metric).

• Head Diameter: 1/4 - 1 or 6mm - 20mm
• Metric and Imperial sizes
• Round and Diamond pins

Precision bullet-nose locating pins are commonly paired with matching bushings to accurately align two parts of a fixture. Typically, a Bullet-Nose Round Pin and a Bullet-Nose Diamond Pin are used together to align two holes without causing interference. The diamond pin is designed to locate in only one axis, preventing any binding. The pin's shank diameter matches the outer diameter (OD) of the bushing, ensuring that the installation holes can be bored simultaneously in both fixture pieces for enhanced precision.

• Round, Diamond and Bushings
• Imperial and Metric
• External Diameter - 9/16 - 1-1/2 or .512 - .866

A precision locating pin is commonly used with a matching bushing to align two parts of a fixture. The pin’s head and shank diameters are concentric within .0005" TIR. Available in pin diameters of 1/4", 5/16", 3/8", and 1/2" (6mm, 8mm, 10mm, and 12mm in metric). A precision bushing is used with a Bullet-Nose Dowel to align two components of a fixture. The bushing’s ID and OD are concentric within .0003" TIR. Available for pin diameters of 1/4", 5/16", 3/8", and 1/2" (6mm, 8mm, 10mm, and 12mm in metric).

• Imperial and Metric
• A Diameter - 1/4 - 1/2  6mm - 12mm
• B Diameter - 1/4 - 1/2  6mm - 12mm

Carr Lanes cone locating pin is designed to be used with the matching bushing. These pins are ideal for the fast assembly of two fixture parts, as they help accommodate significant misalignment. The pin's shank diameter and the bushing's outer diameter are precisely the same, enabling both fixture pieces to be bored for the installation hole simultaneously, ensuring enhanced accuracy. The mating bushing is paired with a Cone Locator Pin to align two pieces of a fixture.  These are offered with 1/2 and 3/4" shank diameters (12 and 20mm in metric).

• Pin and Bushing
• Available in imperial and metric sizes

These precision locating pins are ideal for positioning workpieces due to the broad range of available head diameters, allowing them to fit machined holes in the part.  Along with standard diameters, custom head sizes ranging from .1150" to 1.0400" can be quickly produced in .0001" increments to meet specific requirements.  Typically, a Round Locating Pin and a Diamond Locating Pin are used together to align from two holes without causing interference, as the Diamond Locating Pin is specially relieved for this purpose. The press-fit shank is designed for permanent installation whereas the lockscrew variant is manufactured with a slip-fit shank for renewable installation.

• Round and Diamond Lockscrew Type
• Metric and Imperial sizes
• Shank Diameter - 5/16 - 1
