What are Detent Pins?
Detent pins are a type of fastener that are commonly used to secure two or more objects together. They are designed to be easy to use, and can be inserted and removed quickly and easily. Detent pins are used in a wide range of applications, from industrial machinery to consumer products.
Definition
Detent pins are a type of pin that are designed to be inserted into a hole or slot to hold two or more objects together. They typically feature a spring-loaded ball or locking mechanism that helps to keep the pin in place, and can be easily removed by pulling on a ring or handle.
Working Principle
Detent pins work on a simple principle: when the pin is inserted into a hole or slot, the spring-loaded ball or locking mechanism engages, holding the pin in place. To remove the pin, the user simply pulls on a ring or handle, which disengages the locking mechanism and allows the pin to be easily removed.
Detent pins come in a variety of sizes and shapes, and can be made from a range of materials, including stainless steel, aluminum, and plastic. They are commonly used in applications where the objects being secured need to be easily and quickly removed, such as in machinery and equipment that requires frequent maintenance or repair.
In summary, detent pins are a type of fastener that are designed to be easily inserted and removed, and are commonly used in a wide range of applications. They work by using a spring-loaded ball or locking mechanism to hold the pin in place, and can be easily removed by pulling on a ring or handle.
Types of Detent Pins
Detent pins are versatile fasteners that come in a variety of shapes and sizes. They are commonly used in industrial applications to align and secure machine parts, as well as in consumer products like furniture and sporting equipment. This section will cover the most common types of detent pins.
Ball Detent Pins
Ball detent pins are the most common type of detent pin. They consist of a shank with a spring-loaded ball bearing at the end. When the pin is inserted into a hole, the ball bearing snaps into a detent or groove, holding the pin in place. Ball detent pins are often used in applications where frequent removal and reinsertion of the pin is required.
Knob Detent Pins
Knob detent pins are similar to ball detent pins, but they have a knob or handle attached to the shank. This makes them easier to grip and manipulate, especially in tight spaces. Knob detent pins are often used in furniture assembly and other applications where quick and easy removal is required.
Threaded Detent Pins
Threaded detent pins have threads on the shank that allow them to be screwed into a threaded hole. They have a spring-loaded ball bearing that snaps into a detent or groove, holding the pin in place. Threaded detent pins are often used in applications where a secure, threaded connection is required.
Hitch Pin
A hitch pin is a type of detent pin that is used to secure a trailer hitch or other towing equipment. It consists of a shank with a spring-loaded ball bearing at the end, and a loop or ring attached to the other end. The loop or ring is used to attach the hitch pin to the towing equipment.
Clevis Pin
A clevis pin is a type of detent pin that is used to attach a clevis or other fitting to a shaft or rod. It consists of a shank with a hole through the end, and a spring-loaded ball bearing that snaps into a detent or groove. Clevis pins are often used in agricultural equipment and other heavy machinery.
Detent pins come in a variety of shapes and sizes to suit different applications. Whether you need a ball detent pin for frequent removal, a knob detent pin for easy manipulation, or a threaded detent pin for a secure connection, there is a detent pin that will meet your needs.

Detent pins are used in a wide range of applications, including aerospace, automotive, and industrial machinery. They are made from different materials, each with unique properties that make them suitable for specific applications. In this section, we will explore the most common materials used for detent pins.
Stainless Steel
Stainless steel is one of the most common materials used for detent pins. It is a corrosion-resistant alloy that contains at least 10.5% chromium. Stainless steel detent pins are ideal for applications that require high strength and resistance to corrosion, such as marine and food processing industries. They are also suitable for applications that require high-temperature resistance.
Carbon Steel
Carbon steel is another popular material used for detent pins. It is an alloy that contains carbon and iron. Carbon steel detent pins are strong and durable, making them ideal for heavy-duty applications. They are also cost-effective, making them a popular choice for applications that require large quantities of detent pins.
316 Stainless Steel
316 stainless steel is a type of stainless steel that contains molybdenum. It is more corrosion-resistant than other types of stainless steel, making it ideal for applications that require high resistance to corrosion, such as marine and chemical processing industries. 316 stainless steel detent pins are also suitable for applications that require high strength and durability.
Detent pins can also be made from other materials, such as brass, aluminum, and titanium. The choice of material depends on the specific application requirements, including strength, corrosion resistance, and temperature resistance.
In conclusion, the choice of material for detent pins depends on the specific application requirements. Stainless steel, carbon steel, and 316 stainless steel are the most common materials used for detent pins. Each material has unique properties that make it suitable for specific applications.
Features of Detent Pins
Detent pins, also known as quick-release pins, are mechanical fasteners used to hold two or more objects together. They are designed for applications that require rapid and frequent assembly and disassembly of specific products or objects. Detent pins are known for their reliability, ease of use, and versatility. In this section, we will discuss the features of detent pins.
Solid Shank
The solid shank is the main body of the detent pin. It is a cylindrical rod that is inserted into the holes of the objects to be fastened. The shank is made of various materials, including stainless steel, carbon steel, and aluminum. The diameter of the shank is usually determined by the size of the holes it will be inserted into.
Spring-Loaded Locking Balls
Detent pins have one or two spring-loaded locking balls that are located at one end of the shank. These balls are designed to lock into place when the detent pin is inserted into the hole. The locking balls are made of hardened steel, which ensures durability and strength.
Pull Ring/Lanyard
The pull ring or lanyard is attached to the other end of the detent pin. It is used to pull the pin out of the hole when disassembling the objects. The pull ring or lanyard can be made of various materials, including stainless steel, nylon, or polyester.
Length
The length of the detent pin is determined by the distance between the locking balls and the pull ring. The length of the pin should be slightly longer than the thickness of the objects being fastened. This ensures that the locking balls engage properly and hold the objects securely.
Diameter
The diameter of the detent pin is determined by the size of the holes it will be inserted into. The diameter of the shank should be slightly smaller than the diameter of the holes to ensure a snug fit.
Detent pins are available in various sizes, materials, and configurations. They are used in a wide range of applications, including aerospace, automotive, marine, and industrial. Detent pins are known for their ease of use, reliability, and versatility.
