Product Description

Open mouth pin is a type of pin, described as follows:

Basic definition

An open mouth pin, often referred to as a spring or safety pin, is an essential mechanical component in the realm of metal hardware. Crafted from premium-grade steel or other elastic and robust materials, these pins boast an ingenious design characterized by one or more openings that endow them with remarkable elasticity.

Main features

1. Shape and structure: Designed with precision, open mouth pins typically feature a cylindrical form with strategic openings at either end. This clever construction enables the split pin to seamlessly integrate into a designated hole, where it can then be artfully folded outward to secure or connect multiple components with ease.

2. Elasticity and toughness: Renowned for their exceptional elasticity and toughness, open mouth pins can endure repeated bending without succumbing to cracks or breaks. This resilience ensures that the split pin delivers steadfast holding power when securing components, while also allowing for effortless disassembly and reconnection.

Action and use

1. Fixed function: The primary role of a split pin is to firmly anchor and unite two or more components, safeguarding them against movement or loosening. A prime example is its use in bolted connections, where the split pin is inserted through the bolt tail hole and nut groove, effectively preventing the nut from loosening by acting as a reliable barrier.

2. Wide application: Thanks to its distinctive shape and superior performance traits, the open-end pin finds extensive application across diverse industries, including machinery, automotive, aerospace, maritime, furniture, and electronics. In countless mechanical assemblies, split pins serve as indispensable elements for fixing, connecting, and mitigating loosening.

Specifications and standards

1. Nominal specifications: Open-end pins are available in a versatile range of nominal sizes, typically spanning from 0.6mm to 20mm, allowing for tailored selection based on specific requirements and applications.

2. Standard specifications: The manufacturing and utilization of open-end pins adhere to prescribed standards, such as the Chinese national standard GB/T 91-2000. These standards meticulously outline the fundamental dimensions, technical criteria, and acceptance tests essential for open-end pins.

Installation and Precautions

1. Installation method: For optimal installation of a split pin, ensure its nominal size precisely matches the diameter of the pin hole. It is crucial to avoid substituting with wire or other materials. During insertion, utilize hands or pliers for gentle guidance, eschewing tools like hammers that may compromise the pin's integrity. Employ a screwdriver or similar tool to unfold the pin, generally to a 60° angle, and in cases of collision, modestly roll up the opening pin.

2. Precautions: Vigilance is vital when using split pins; meticulously inspect for surface defects such as burrs, cracks, or rust to prevent the use of flawed pins. Additionally, verify the correct and secure placement of the pin to fully exploit its connecting and fixing capabilities.

In essence, open-end pins are pivotal mechanical components with a crucial role in ensuring the stability and safety of mechanical connections. By comprehensively understanding their attributes, functionalities, specifications, and installation techniques, users can make informed choices and deploy split pins to their fullest potential.
