Types of Other Fasteners
 

The other fasteners produced by our company mainly include the following types:

Long Nose Spring Plunger

The long-nose spring plunger is a mechanical fastener that is designed for precise positioning and secure fastening. with its extended nose, allowing it to reach deep into components for a reliable fastening. The plunger consists of a spring and a plunger body, where the spring provides the force to hold parts together, and the long nose ensures a firm connection.

Flat-Head Quick-Release Pins

The flat-head quick-release pin is a fastening component designed for quick connection and removal. It consists of a cylindrical pin and a steel ball on the top. This design ensures a secure fit while allowing for fast disassembly, which makes it ideal for frequent assembly and removal applications.

Loop-Grip Quick-Release Pins

The loop-grip quick-release pins are mechanical fasteners designed for easy and fast assembly or disassembly. They are commonly used in equipment that requires frequent setup or takedown.

 

Advantages of Other Fasteners

 

Long Nose Spring Plunger

 

Long nose spring plungers have many advantages, including:


Simplicity that Leads to Productivity
You do not need to use complex spring plungers to make all your goals a reality. Simple hardware is enough to achieve the right lock and support. Proper locking and cushion are achievable even with the use of the simplest spring plungers.


Easy to Install: A Minute of Setup
Compared to non-loaded and standard spring, the spring-loaded devices require a do-it-yourself installation. Easy setup has been associated with the tools since availability.


Accurate and Repeatable Forces
Standard springs are uncomfortable to utilize. This is especially true when you need accurate and repeatable forces from the springs. Sometimes, you may think that you commit a mistake during the process. It’s good to repeat the procedure.


Available at a Competitive Pricing that Leads to Huge Savings
Given their utility and advantage in the manufacturing industry, you may assume that spring-loaded tools are expensive.

FAQ

 

Q: What are the components of a long nose spring plunger?

A: It usually consists of a metal body, a compression spring inside the body, and a long nose at the end of the plunger.

Q: What materials are long nose spring plungers made of?

A: Common materials include steel, stainless steel, brass, and some plastics like Delrin. The choice of material depends on application requirements such as strength, corrosion resistance, and temperature resistance.

Q: How does a long nose spring plunger work?

A: When installed in a threaded hole, the spring inside the plunger is compressed by the force applied to the nose. This allows the plunger to provide a constant force against the workpiece, maintaining the position of the part until the external force is released.

Q: How to install a long nose spring plunger?

A: First, drill a hole deep enough for the spring - loaded device to fit into. The size of the installation hole should be slightly larger than the diameter of the spring plunger. Then, use a screwdriver or hex socket to install the plunger into the threaded hole. It is recommended to use a bottom tap to create threads in the installation hole to ensure a secure fit.

Q: How to choose the right long nose spring plunger?

A: Consider factors such as the required clamping force, stroke, nose shape, thread diameter, and material. Also, consider the specific application environment, such as whether it is exposed to corrosive media or high temperatures.

Q: Can long nose spring plungers be used in high - temperature environments?

A: It depends on the material of the plunger. Some high - temperature - resistant materials such as certain stainless steels can be used in high - temperature environments, but ordinary plastic - based materials may have limitations.
