What is a Spring Pin? Complete Guide to Flexible Fastening Technology
A spring pin is a hollow, cylindrical fastener designed to fit into a drilled hole and apply outward pressure against the walls. HENNLICH manufactures high-quality spring pin solutions that provide a secure, self-retaining fit without requiring additional locking mechanisms.
Also known as a rolled spring pin, this component is formed by rolling metal into a cylindrical shape with a longitudinal slit. This design allows the pin to compress during installation and expand once inserted, ensuring a tight and vibration-resistant connection.
HENNLICH spring pins are widely used across industries for their ability to handle dynamic loads, absorb shocks, and maintain alignment even under challenging operating conditions.
Variants of Spring Pin
HENNLICH provides a wide range of spring pin variants to meet diverse industrial requirements:
Rolled Spring Pin
A rolled spring pin is the most commonly used type, featuring a slotted design for flexibility and easy installation. HENNLICH rolled spring pins are ideal for general-purpose applications requiring durability and shock absorption.
Slotted Spring Pin
This variant includes a longitudinal slot that enables compression during installation. HENNLICH slotted pins are suitable for applications requiring quick assembly and removal.
Coiled Spring Pin
A coiled spring pin is made from layered coils of metal, offering superior strength and fatigue resistance. HENNLICH supplies these pins for high-performance and heavy-load applications.
Tapered Spring Pin
These pins have a slight taper that simplifies installation in precision alignment applications. HENNLICH ensures accurate manufacturing for consistent performance.
Heavy-Duty Spring Pin
Designed for demanding environments, HENNLICH heavy-duty spring pins provide enhanced load-bearing capacity and long-term durability.
