1. Can the knob plunger withstand radial force?

 

It is not recommended that the knob plunger withstand radial cutting force, which is prone to product damage and fracture. Generally, it can only withstand axial force.
 

2. What is the function of the knob plunger?

 

The knob and handle can be used to manually operate the pin in and out, which is suitable for temporary positioning of the workpiece.

 

3. What are the general categories of knob plungers?

 

According to the method of use, it can be divided into reset type, self-locking type and handle type. According to the type of thread, it can be divided into coarse thread type and fine thread type.

 

4. Compared with the coarse thread type, what are the characteristics of the fine thread type?

 

The fine thread type is suitable for environments where the ejection amount of the pin is finely adjusted. Compared with the coarse thread, it can achieve more accurate positioning.

 

5. What is the difference between the reset type and the self-locking type knob plunger?

 

The self-locking type can pull out the knob and rotate 90° to lock the front end, while keeping it pulled out and rotating 90° to unlock it.

1. What does the anti-loosening treatment of the ball plunger mean?

It is fixed with an anaerobic gas adhesive filled in microcapsules. Once loose, it will fail, so an anaerobic adhesive for threads is required. The anti-loosening effect is best when it is placed under conditions exceeding 25 degrees Celsius for 72 hours.

 

2. What do load min and load max mean?

Load min indicates the initial load value, and max indicates the load value when the ball head is pressed to the maximum limit.

 

3. What is the difference between a ball plunger and a spring plunger?

The head of the ball plunger is a steel ball, and the stroke is the displacement of the steel ball part. The front section of the spring plunger is pin-shaped, and the displacement stroke of the pin is used to achieve temporary positioning and indexing of the workpiece.

1. What types of locking screws are there?

According to the tightening method, they are mainly divided into straight column type and bolt type. According to the use method, they can be divided into ball head type, angle type and stop type.
 

2. Do locking screws have hardness?

The ball head has hardness, and the hardness is above 55HRC. Products made of SCM435 also have hardness in the thread part (38~43HRC), and SUS304 has no hardness.
 

3. What parts sold by ZC are locking screws generally used with?

It is recommended to use with nuts, workpiece guide blocks, etc.
