After the fastener is surface treated, the appearance of the fastener can be more aesthetically pleasing, and the method can improve the corrosion resistance of the stainless steel fastener bolt itself.

Professional fastener bolt specifications: Twist-cut high-strength bolts should be completely unscrewed from the end of the tail plume to the end of the screw, not allowed to miss. Due to the narrow space, high strength bolt wrenches should not be operated. It can be fitted with a heightening sleeve or a hand wrench. When the bolt is low and the deviation value is not large (within 15mm), the bolt can be baked into red with oxyacetylene, and then dripped on the concrete foundation to corrode and affect the basic quality. When the bolt is too high, the upper part must be separated to retighten. When setting the thread, the deviation of the screw height of the oil material must be avoided.
