Quickly transforms into a screw that won't loosen! 'Pre-coat processing' to prevent screw loosening.
Just tighten it to lock the screw! No need to apply adhesive, and it can be reused repeatedly. Designed with a unique coating method to prevent your screws from loosening.
The "Pre-Coating Process" provided by Sankei Industries is a coating method that applies a non-sticky adhesive to screws in advance, preventing them from loosening when tightened. When the screw is screwed in, microcapsules contained in the adhesive break, providing both locking and sealing effects simultaneously. This method is commonly used in the automotive industry as a measure to prevent screw loosening. Our company can also provide a coating that does not apply adhesive to the tip of the screw, tailored to customer requests. This does not reduce the efficiency of the fastening work. In fact, it improves work efficiency by eliminating the need for adhesive work on-site, leading to significant cost savings as nuts are also unnecessary. 【Features】 ■ Simply bring screws pre-coated with non-sticky adhesive to the site ■ Achieves increased work efficiency and cost reduction. Can be reused multiple times ■ Strength is further enhanced by using nuts in conjunction ■ Compatible with various shapes of screws and bolts ■ Provides a lubricating effect on materials with high torque coefficients, reducing issues like seizing We also offer quick estimates and short delivery times. Proposals tailored to your requests and applications are also possible. *For more details, please refer to the PDF document or feel free to contact us.

Company information
Sansei Industrial Co., Ltd. is a company located in Anjo City, Aichi Prefecture, that specializes in resin coating processing and pre-coating processing (bond loosening prevention processing). The resin coating processing uses powdered resin and employs the fluid immersion method, which is the most widely used for substrates such as metal and glass. This results in a finish that is uniform and glossy. In pre-coating processing, a high-strength epoxy resin-based adhesive is used, which primarily consists of epoxy resin encapsulated in microcapsules. Fastening with screws and bolts is an essential technology for any industrial product. The use of pre-coated bolts improves the quality of fastening.
