A Phillips screw has been completely smashed, and the middle cross groove has become a hole. And the screw cap exposed to the outside of the screw is very thin, almost pinch-off with the pliers, and the screw space is also narrow.  How to remove a broken phillips screw ? Here are some ways to introduce： Only if necessary, if the screw is rusted or stuck with glue, apply penetrating oil or heat. Method 1: hammer and screwdriver Method 2: hammer and chisel Method 3: hammer and pointer Method 4: welding a nut Method 5: with a special extractor Method 6: drilling a partially Method 7: make new thread and put a reducer how to remove a broken phillips screw ?, welcome message: sst@szsst88.com

For example, the screw size is M5X8 , M6X42 , M8X50 and so on, and the material is stainless steel 304. These information are enough to calculate the  tensile strength of stainless steel screw ? First of all, we need to know that screws have different specifications and grades, and different grades correspond to different strength requirements. The strength requirement is a number of minimum, and the measured result must reach or exceed the specified value. For example, stainless steel 304 screws, bolts and studs are divided into 500 Pa, 700 Pa ,800 Pa , so we can know the maximum pulling force of the screw is about 10000N, 14000N, 16000N. Stainless Steel 304 Screws , Specification  : M5X8 ,M6X42, M8X50 etc , generally they are a2-70, which mean the tensile strength is above 700MPa , the maximum tension of the screw is over 14000N. Shenzhen Shi Shi Tong Metal Products Co., Ltd very have an smart advantage in stainless steel 304 screws, which is a screw manufactuer in She...

Mr. Cheng previously purchased a hex socket head cap screw  in Zhejiang, 8.8 grade nickel plated, the screws bought look very beautiful, and the price is very cheap. However, there was a problem when using it. I don't know what happened. The screw he bought was easily broken. Mr. Cheng wondered why the screws that others bought were not easy to break, and there would be no problems. Later, when Mr. Cheng tested the hex socket head cap screw , he found that the torque did not reach 8.8. Mr. Cheng gave this question back to his supplier. The supplier re-offered the goods to Mr. Cheng. There is still a problem. Finally, Mr. Cheng did not find any more. Occasionally, Mr. Cheng contacted Shi  S hi  T ong and first ordered samples from Shi  S hi  T ong to go back to the test. A week later, Mr. Cheng said that our hex socket head cap screw  test was passed, and this time it will be officially purchased at Shi  S hi  T ong. How about the qual...

Joel sent us an enquiry last month, saying that I want  fillister head machine screws . And gave us the drawings. And asked us a few questions: One is whether the  fillister head machine screws  or the screw should be opened; how long will it be delivered; can it be tested for 500 hours in salt spray; if you want this cup, it is not so easy to fall out. After that, we answered the questions according to Joel and gave the corresponding solutions. After confirming that all the problems can be solved, Joel immediately placed an order for us, and said that our products were of good quality in the first delivery, and they met their requirements after testing. In this month, the order for the  fillister head machine screws  is added. www.sstls.com www.szsst88.com

If you are a buyer of screws, you should have encountered a different offer for the same size of pan head machine screws . Do you think that the supplier is in the pit? Actually not, there are reasons for different prices. Why are the screws of the same specifications different in price? Before answering this question, you need to know that the materials of the same specifications are different. For example, the same size of the pan head machine screws , the choice of materials is different, the quotation will be different, if you choose carbon steel material production than the choice Stainless steel is cheaper to produce because stainless steel is more expensive than carbon steel. So there will be different prices. Another reason is that the difference in production process will also result in different screw prices of the same size. The screw production process generally has cold heading and cnc processing. The screws produced by the cold heading process are suitable...

The shoulder  screw  is simply a non-standard screw with two or more steps. Shoulder screw , also known as shoulder bolt, or clamping bolt, It are used in a wide range of precision gaskets and bearings. The scapula is uniquely identifiable by the long, cylindrical, middle (shoulder), which is wider than the threaded portion but narrower than the head. When screwed into the surface, the stepped portion remains above the aperture, allowing rotation of accessory components such as pulleys, gears, mechanical components, and rolling wheels. They can also be used to attach stripping plates to secure high torque in a limited clearance environment. The general shoulder screw  are not in stock and need to be opened for custom production.  Shenzhen Shi  S hi  T ong Screw Factory uses all-professional fastener production machines, high-quality wire and 20 years of experience in production, sales and sales of standard and non-standard shoulder screw .
