"I was just wondering if I could make a screw that wouldn't loosen."

"I thought about it later."

"I have been thinking about this for a while, and then my profession reminded me."

Having said this, Lao Guo showed a touch of pride on his face.

"When I went back to make the relief sculpture, I was hammering it, and I thought, if the characters' hairs all look the same, no matter how thin they are, they won't look the same."

"When I touch it, I feel nothing."

"On the contrary, it is the kind that has high and low levels, and is uneven, which makes it feel like an obstacle to the touch."

"so..."

"So you made threads like this, right?"

Chang Mingjie couldn't listen anymore. This old Guo had become a member of the R&D department. He was so capable before, but he kept talking in a glib tone.

When Lao Guo heard what Chang Mingjie said, he nodded immediately, "Yes, so I tried to make a few screws."

"I didn't expect it to be really useful."

Yang Xiaotao picked up the screw and silently felt the thread.

To be honest, in the eyes of his professional, these two screws are really rough. Even an apprentice fitter can drive them better than him.

But for the two methods of superimposing threads, let alone a fitter apprentice, even he, an eighth-level fitter, had never thought about this aspect.

"Let's go take a look."

A flash of light flashed in Yang Xiaotao's eyes. If it can be done, the design of machine tools and the performance of some special machines will be greatly improved.

"good."

Lao Guo smiled and quickly led Yang Xiaotao and the two of them to the machine tool production side.

When they came to a semi-automatic Venus machine tool, the workers who were operating it saw the factory manager Yang and their supervisor coming over. They thought something had happened and quickly stopped the machine tool. All of them looked a little nervous.

But when the three of them came to them, Lao Guo pointed to the two screws under the machine tool.

"I drove out these two screws. The screws were easy to loosen at the time, so I found new screws and changed them. Now you see, they don't move at all."

Lao Guo pointed to the place where the machine tool was fixed, and Yang Xiaotao hurriedly knelt down to check.

"You guys are working normally."

Chang Mingjie said something, and everyone realized that they were not here this time, so they continued working.

Yang Xiaotao stared at the fixed screws. When the machine tool processed the components, the whole machine would tremble to a certain extent, and the fixed screws would also tremble.

Although it is not visible in a short period of time, it is easy to become loose after a long time.

This situation often occurs not only in machine tools, but also in previous steel rolling mills.

“How long have you had this screw?”

Yang Xiaotao asked people to stop and asked casually.

Lao Guo thought for a while and said, "About a month or so."

"I dug out this bolt myself, so it may not match very well."

Lao Guo was explaining on the side, but Yang Xiaotao raised his head and said, "Give me a wrench and pliers."

After hearing this, the worker hurriedly stopped the machine tool, and then someone handed the tool to Yang Xiaotao.

After Yang Xiaotao took it, he first found a normal screw to try, and then tightened this special screw.

In terms of strength between the two parties, Yang Xiaotao obviously felt that the latter one had more difficulty.

However, Yang Xiaotao did not rush to draw conclusions.

"Old Chang, I remember that our factory's assessment team tested the screw torque. Please ask someone to do it."

Chang Mingjie immediately agreed.

After a while, two people ran in from outside, and the leader was Guo Liang, the leader of the assessment and test team.

Coming closer, Guo Liang said hello to Yang Xiaotao.

When Yang Xiaotao took the first-level fitter exam, he was the one in charge of the assessment.

But after so many years, Yang Xiaotao has become President Yang, and he is still the leader of the assessment team.

"Team Leader Guo, please test the torque of these two screws."

Yang Xiaotao spoke directly and Guo Liang nodded.

When I received the news, I had already brought my equipment.

Knowing that it was to test the torque of the screw, I took out the test torque wrench and tested it carefully.

After the original screw test was completed, Yang Xiaotao looked at the scale on the wrench and it pointed to five.

After replacing the screws with special threads, although Guo Liang was curious, he also tested carefully until he heard a click. Yang Xiaotao quickly went up to check, eleven!

Yang Xiaotao looked serious, and Chang Mingjie's eyes widened.

Even Guo Liang didn't believe it, so he took the test again and it was still 11.

The only one whose expression didn't change much was Lao Guo.

Of course, he was not calm, but he didn't know what the number on the wrench meant.

"Mr. Yang, that's right, it's Eleven."

Yang Xiaotao laughed immediately after hearing this, then came to Lao Guo and patted his shoulder gently, "Comrade Lao Guo, congratulations on your meritorious service."

Yang Xiaotao smiled, and Lao Guo also laughed after hearing this.

"It doesn't matter whether you have meritorious service or not, as long as it helps the machinery factory."

"Help, there is, absolutely."

Yang Xiaotao said affirmatively, and then added, "This invention of yours may be useful to the whole country."

Lao Guo didn't care after hearing this.

In fact, the original vision was that I didn’t want to follow Lao Liu to look at machine tools.

But if the machine tool is not optimistic, problems can really arise.

Now that we have this kind of screw, we no longer need to look at the machine tool.
