The spring-like locking force created by the Groov-Pin, in a hole the size of the pin nominal diameter, is very resistant to vibration and shock. In fact, forces greater than the maximum insertion force are required to move a fully engaged pin. Even in the case of axial displacement, the Groov-Pin retains holding force until it is fully disengaged.

The Groov-Pin is a solid metal pin with up to twice the shear strength of a spring pin of the same diameter. The shear resistance of allow steel Groov-Pins can be 40% higher than that of a heavy-duty spring pin. Groov-Pins also provide a smooth surface around the diameter and uniform diameter along the unexpanded length for better cosmetic appearance and superior performance as an axle or hinge pin. The smooth surface along the unexpanded length and at the ends reduces the accumulation of abrasives and other undesirable materials. The strength of the solid pin body is not orientation dependent, as is the case with some spring pins.

A wide variety of groove types are available to suit almost any application. To provide free rotation surfaces, smooth surfaces for handles, or necks for springs, the groove length can be selected and positioned where needed along the pin. To facilitate automatic insertion or to maximize the holding power of the pin, different shapes may be selected for the groove and the end of the pin.

Locking depends on the compression of the Groov-Pin itself, rather than the deformation of the base material. Locking grooves can be tailored to lock parts of the pin while allowing other parts to rotate freely.  Consequently, the Groov-Pin is well suited for applications in hardened or unhardened steels, as well as aluminum, brass and plastics.  The solid groov-pin has better visual appearance compared to coil or spring pins and does not collect debris.

Since the tolerance requirements on holes accepting Groov-Pins are relatively loose, demands on the manufacturing process are reduced. Groov-Pins require only a straight drilled hole. No reaming, milling or tapping is necessary.

The Groov-Pin can be driven manually or automatically, by hand, air cylinder, or hydraulic press. Also, it is a one-piece retainer. Simplicity of installation can speed assembly and save labor cost.

Properly designed assemblies, locked or aligned with Groov-Pins, can be separated without destroying the pins. The same pins can be used again with little or no reduction in performance.

The locking properties of grooves can be used with pins made of many different materials, opening a wide range of design options where other material properties, such as conductivity or corrosion-resistance, may be important.
