Onserts can be used not only with standard materials such as steel, aluminum, and resin, but also with glass and CFRP. In situations where mechanical fastening or welding cannot be used, a transparent plastic mount is formed and bonded using a light-curing adhesive. Onserts are effective in cases where it is difficult to process the base material, such as drilling pilot holes, in areas where welding is impossible, or in situations where appearance is a major concern. For assembly, dedicated hand tools and automation options are available. 【Features】 - Short curing time (< 4 seconds) - No need for pilot holes - Fastening to thin sheets - Usable on surface-treated base materials - Excellent design quality - Compatible with various base materials - No heat generation

This is a locking element designed to prevent unauthorized manipulation of hexagonal socket bolts. In safety-related applications, it is necessary to prevent unauthorized individuals from tampering. This is particularly relevant in complex machines and systems where changes to the initial state could lead to dangerous situations. It provides a quick and clean solution in such cases. It can be easily inserted into the hexagonal socket using handling aids. It is fixed at the same plane as the screw head or slightly recessed. This prevents the use of tools and unauthorized manipulation. It is recommended in all areas where the safety of people and machines is at risk. Due to its easy installation and unique locking effect, it is also suitable for many other applications, such as avoiding screw marking and preventing clogging of holes due to dirt in outdoor and food industries.
