Why is it recommended to change the material of pan head cross screws to carbon steel?

Yesterday, Shi Shi Tong screw manufacturer received a new drawing from an old customer, Ms. Huang. There are two types of pan head cross screws. She asked us to provide her with a quotation for stainless steel 304 material.

Because Ms. Huang’s drawing is marked with stainless steel 304, which requires A2-70. Ms. Song asked Ms. Huang if the material must be A2-70. Our regular one is A2-50. A2-70 needs to be ordered, at least 100kg. According to the quantity of pan-head cross screws that Ms. Huang currently needs, 100kg can be made 10 times faster. And the lead time for ordering materials is almost 15 days. Can you wait that long?

Ms. Huang said that we can just use the materials we have now, and there is no need to order materials specially. They also said that they require that the pan head cross screws can be sucked by the screwdriver when used, so they require them to be magnetic.

Although 304 stainless steel screws are magnetic, they are weakly magnetic. Ms. Song was worried that Ms. Huang would not understand how weak the magnet was, so she found two small screws, one stainless steel and one carbon steel. Use a screwdriver to tighten the stainless steel one, but the carbon steel one can be sucked by the screwdriver. live.

Therefore, Ms. Song suggested that Ms. Huang change the material of the pan-head Phillips screws to carbon steel if she requires them to be sucked by the screwdriver. Ms. Huang said that they need to internally confirm what material the pan head cross screws are used for.
