Product Introduction
The KPO fastening system is a clip-type fastening device designed specifically for railway track systems. It is divided into three types: KPO3, KPO6, and KPO9. The system consists of KPO clips, anchor spikes, high-strength bolt connection pairs, rail rubber pads, and iron pads. The clips are made of Q235 steel, and the key load-bearing parts are made of 35# or 45# medium carbon steel and are quenched and tempered.
It is mainly used in scenarios such as heavy-duty railway lines and mining railways that require high track stability, and prevents rail displacement through strong clamping force. Its advantages are easy maintenance and long service life. The production process covers steel smelting, forging, mechanical cutting, heat treatment, and surface anti-corrosion coating to ensure that the product meets the stringent requirements of heavy-duty transportation.
Features of KPO Railroad Fasteners
Strong structure: The rigid connection method can firmly fix the rails on the sleepers, effectively preventing the rails from loosening or shifting. It performs well under heavy loads and harsh environmental conditions and is suitable for heavy-duty railways, port transportation, and mining tracks, which require high track stability.
Strong applicability: It can adapt to a variety of rail sections, such as UIC 54, UIC 60, 50kg rails, 60kg rails, S49, etc., to meet the needs of different railway lines.
Good durability: The gussets of the KPO fastener system include KPO3, KPO5, KPO6 and KPO9. Compared with ordinary fastener systems, they have better buckling pressure and longer service life, and have been widely used in track construction around the world.

Product Packaging & Delivery
Magnetic partitions + plastic box combination: Design a plastic box with magnetic partitions inside, and the partitions can be freely adjusted according to the size of the fasteners. Nuts, bolts, etc. are classified according to specifications and fixed in the box using the magnetic properties of the partitions to prevent displacement. The box cover is equipped with a sealing strip, which forms a dust-proof and moisture-proof structure when closed. When multiple boxes are stacked, the positioning bumps on the bottom of the box body precisely fit the grooves on the upper layer, and the outermost layer is wrapped with shrink film as a whole, which is convenient for efficient inventory and handling.
