Roll Pins / Spring Pins
Roll pins, also known as spring pins or tension pins, are essential self-retaining mechanical fasteners designed to provide strong, reliable connections between two or more machine components. Their unique spring action allows them to compress during insertion into a pre-drilled hole, then expand to exert outward pressure, securely locking them in place. This inherent flexibility makes roll pins a highly adaptable and cost-effective alternative to traditional fasteners like taper pins, straight pins, and set screws.
Why Choose Roll Pins / Spring Pins?
- Simplified Design & Assembly: Eliminate the need for complex machining or threading, streamlining your production process and reducing costs.
- Exceptional Durability & Strength: The resilient spring steel construction provides robust holding power, ensuring long-lasting performance even under demanding conditions.
- Versatile Applications: Spring pins can function as rivets, dowels, hinge pins, or cotter pins, offering a multi-purpose solution for diverse engineering needs.
- Vibration Resistance: The constant outward pressure of the spring pin effectively resists loosening caused by vibration, ensuring a secure and stable connection.
Material & Finish Options for Specific Needs:
- Standard Steel: Provides a reliable and economical solution for general-purpose applications.
- Stainless Steel (Type 420 - Magnetic): Offers enhanced corrosion resistance compared to standard steel, ideal for applications where moderate moisture exposure is a concern.
- Stainless Steel (Type 300 - Non-Magnetic): Provides superior corrosion resistance, making it perfect for demanding environments such as electronics, food processing, and marine applications.
- Black Oxide Coating: Delivers a sleek, decorative finish while reducing glare and friction, enhancing both aesthetics and performance.
