Commonly used as locking devices, pivots, bearing faces or locating elements where there is not a high degree of end load Available with many different groove types Typically zinc-plated, made from unhardened, low-carbon steel – but available in a wide range of finishes and heat treatments for shear resistance Wide range of diameters, lengths and end configurations available Shortest Lead Times on Custom Grooved Pins: How and When You Need Them Driv-Lok is known for short lead times on custom pins. We haven’t settled on just having the shortest lead time, we continuously look to improve on lead time because in today’s competitive environment, it’s all about time and every day counts.

We have partnered with Stocking Distributors that have immediate delivery. Description Function Dimensions CAD Diagram Success stories The groove of a grooved pin is formed by a swaging operation in which three tools penetrate the nominal diameter of the metal at 120° intervals. This penetration displaces a controlled amount of metal to each side of the grooving tool, forming a raised portion along the side of each groove. The crest of these raised portions forms the expanded diameter or “Dx” dimension which is shown in Figure 1. The Dx is a few thousandths larger than the nominal diameter “D” of the pin. The amount of expansion varies with the diameter of the pin, the material being grooved, and the style of groove.
