Hebei Wotu Fastener Manufacturing Co., Ltd. would like to discuss the following six issues to pay attention to when using and maintaining self-drilling screws.
Today, Hebei Wotu Fastener Manufacturing Co., Ltd. will discuss the following six issues to pay attention to when using and maintaining self-drilling screws, hoping to provide significant assistance to everyone.
1. The rinsing process for self-drilling screws is very important and requires great care. Residue may remain on the surface of the screws during this process. Rinsing should be done after cleaning with a silicate cleaning agent.
2. Self-drilling screws must be stacked properly during tempering heating; otherwise, slight oxidation may occur in the quenching oil.
3. The appearance of white phosphide residue on the surface of high-strength screws indicates (point 1) insufficient attention to detail during inspection.
4. Blackening of the component surface due to chemical reaction indicates that the heat treatment was not thorough, and alkaline residues on the surface were not completely removed. 5. Standard parts may rust during rinsing, so the rinsing water should be changed frequently.
6. Excessive rust indicates that the quenching oil has been used for too long and needs to be added or replaced.
The above six points are summarized by our self-drilling screw manufacturer. We welcome any different opinions from you, and we will make changes and additions as needed to ensure better use. Finally, please remember that we are a self-drilling screw manufacturer in Yongnian. If you need self-drilling screws, please contact Wotu Fasteners!
DIN 931-style half-thread and DIN 933-style full-thread hex bolts should not be selected from diameter and overall length alone. The practical choice depends on the joint stack, required grip, location of the thread transition, available nut engagement, mating hardware, material or property requirement, coating system and governing product specification. A half-thread bolt is not automatically […]
A bolt manufacturer should be evaluated against a defined joint, drawing and acceptance plan—not a product list or unit price alone. Buyers need to verify whether the supplier can manufacture the required geometry, control material and heat-treatment requirements where applicable, manage threads and coatings as one dimensional system, inspect critical characteristics, preserve batch traceability and […]
