Product Introduction
The railway fastener system is a track fastening device composed of high-strength spiral spikes, spring clip clamps, rail damping pads and gauge locking blocks. It can be divided into light-load, medium-load and heavy-load types according to the train axle weight. The light-load type is suitable for sightseeing railways and industrial branches with small traffic volume, the medium-load type meets the needs of ordinary passenger trunk lines, and the heavy-load type uses thickened spring bars and thickened bolts, which is specially designed for 10,000-ton freight trains.
Nabla rail fastener system is a railway track connection device widely used internationally.
Components
Nabla spring clip: It is the core component, usually made of alloy spring steel such as 60Si2MnA, 60Si2CrA, etc., with a thickness of generally 4mm or 4.5mm. Its special shape enables it to generate dynamic and stable buckling pressure on the rail when the nut is tightened.
Insulator: Also known as a support pad, it is made of reinforced nylon 66 (PA66) and is specially designed for Nabla spring clips. It is used for insulation and support between rails and other components. It is suitable for UIC54, UIC60, 50kg/m rails, 60kg/m rails and other specifications.
Screw and nut: Common materials for screws include Q235 (grade 4.6), 35# steel (grade 5.6), 45# steel (grade 8.8), etc., and nuts include 35# steel (grade 5), 45# steel (grade 8), etc., which can be customized according to actual needs.
Spring washer: The material is generally 65Mn, with specifications such as 18.25mm×34mm×78mm, which plays a role in anti-loosening and buffering.

Product Packaging & Delivery
Put the fasteners into the soft silicone sleeve with anti-slip grooves on the bottom, and use the elasticity of silicone to fix the individual parts to prevent surface scratches. Put the fasteners with silicone sleeves into the customized paper honeycomb box. The honeycomb structure provides buffering and reduces weight. The box is equipped with a retractable partition board, which is stored according to specifications. The box cover is closed with a folding lock and the outside is cross-bound with degradable fiber ropes, taking into account both environmental protection and protective performance.
