Specifications These products are used only on railway facilities where conventional butt bolts, due to their smaller dimensions, do not cope with their task, an example is a turnout. In view of the severance of trade and economic ties with Ukraine, where this product is mass-produced, the delivery has become difficult, or rather practically impossible. Products of our production are made strictly in accordance with GOST, from steel grade 35, strength class 8.8, or from steel grade 40x, strength class 10.9 on modern equipment, by hot stamping. The manufacture of these bolts in the forge of our enterprise includes a rather complex labor-intensive and energy-intensive process, which takes place in stages and consists of punching an oval headrest to a rod, punching a round head, and threading. Each batch of bolts on a special stand undergoes tensile tests, after which, under the strict guidance of quality control inspectors, compliance with the specified dimensions, appearance is checked and delivered to the finished product warehouse.
