Pins
Grooved pins feature longitudinal flutes swaged into their solid shanks, which compress elastically upon insertion into standard drilled holes. This radial expansion generates constant outward tension that strongly resists shock and high-frequency vibration without the need for precision reaming. They are frequently utilized as fulcrum pins, retaining elements, and locating shafts in automotive brake systems, valves, and material handling equipment.
Grooved pins are highly reliable, solid press-fit fasteners engineered with longitudinal flutes swaged into their cylindrical shanks. The primary engineering purpose of these flutes is to displace material outward. When the pin is inserted into a standard drilled hole, this displaced material compresses elastically, generating a constant outward radial tension. This unique mechanism firmly anchors the pin and strongly resists shock and high-frequency vibration without requiring expensive precision reaming.
These fluted pins are designed for diverse environments, ranging from light industrial equipment to harsh automotive systems. They are commonly manufactured from robust Steel and Stainless Steel. To combat corrosion and minimize friction during insertion, they are available in a variety of finishes, including Natural, Plain, Oil-Coated, Polished, Passivated, Galvanized, and Plated.
Grooved pins are precision-engineered to meet stringent industrial criteria, ensuring reliable performance in demanding settings.
Because they require only standard drilled holes and offer superior retention under dynamic loads, grooved pins are a versatile fastening solution. They are widely utilized in:
Grooved pins offer a cost-effective, high-performance fastening solution that eliminates the need for precision hole preparation. Their exceptional resistance to shock and vibration makes them a critical component in dynamic assemblies across numerous industrial sectors.
