Preventing Self-Drilling Screws from Slipping During Use
There are many ways to prevent screw slippage. You can choose the best method based on your specific situation. The main methods are as follows:
1. If the problem is with the screw’s material, you can purchase higher-quality screw wire to manufacture the screw. The hardness of the screw wire determines the hardness of the screw. Of course, this is without hardening.
2. If the screw is used on hard materials such as iron plates, and the screw itself is not hard enough, you need to harden it. Hardening also has hardness requirements. Generally, 480-550 HV is sufficient.
3. For slipping screws, you can use methods to increase the strength grade. For example, internal hex bolts and external hex head bolts. Self-drilling screws come in grades 4.8, 8.8, 10.9, and 12.9. If you have a grade 4.8 screw, you can replace it with a grade 8.8, 10.9, or 12.9 screw. In short, replace the lower-grade screw with a higher-grade one.
4. If the threads are slipping, it is recommended to harden the screw and apply adhesive to the threads. This can help prevent loosening.
The self-drilling screw manufacturer, Hebei Wotu Fastener Manufacturing Co., Ltd., uses imported and domestic large-scale steel mill raw materials. Its production equipment is all from Taiwan, and it has a complete testing process and equipment. Operating under a modern enterprise system, it strictly manages according to the ISO9001:2015 quality system.
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 […]
