This product page details the high-quality PIN, SPRNG with part number #688500313, measuring 3mm in diameter by 22mm in length. Manufactured in strict compliance with the ASME B18.8.4M standard, this Type B (Light Duty) spring pin is engineered for exceptional performance and durability in a wide array of mechanical applications.
Key Features & Product Advantages
Our PIN, SPRNG is engineered to simplify assembly while providing superior holding power. Its unique design offers a set of compelling advantages over solid pins and other fasteners.
-
Vibration & Shock Resistance: The elastic nature of the PIN, SPRNG allows it to absorb energy and maintain a secure fit even in high-vibration environments, preventing loosening and ensuring long-term joint integrity.
-
Self-Locking & Secure Fit: After being pressed into a drilled hole, the pin compresses, exerting a continuous radial pressure against the hole walls. This creates a strong frictional hold and reliable retention without the need for additional securing methods.
-
Ease of Installation & Cost-Effective: Installation is a simple press-fit operation, enabling rapid assembly and reducing labor costs. It is ideal for automated production lines, streamlining your manufacturing process.
-
Uniform Weight Distribution: The hollow design ensures consistent weight and strength distribution around the entire circumference, allowing it to handle shear loads from any direction effectively.
-
Interchangeability & Global Standard: Compliance with the ASME B18.8.4M standard guarantees that this PIN, SPRNG is interchangeable with other standard parts, simplifying sourcing, replacement, and design validation worldwide.
