What makes the Russian high-strength fasteners different from European ones?
The standards for high-strength bolts, nuts and washers, operating in Russia and in Europe, are pointed. The basic technical requirements on these standards are compared. The most important differences between the regulatory requirements, which must be considered in the performance of bolted joints of building and industrial structures, are marked out.
Calculation of the connections with self-tapping screws in polymer structures
There considered the connections of plastic details by self-tapping screws. The main factors to consider when using thread extruding screws are given. There noted that when creating designs with the best properties it is necessary to apply the screws with optimized geometry of the thread. As an example, the screws with the Remform profile are considered.
Ways of development of railway fastener manufacturing
The author provides the historical information about development of railway fastener production. The information about the main types of such fasteners and about the Russian manufacturers of the fasteners. The current state of the industry is considered. Based on the requirements of mass development of modern fasteners, the directions for the development of railway fastener production are set.
