Track bolts can be supplied as oval neck bolts, fish bolts, hex bolts, T-bolts or drawing-based custom rail fasteners according to order requirement. Materials include carbon steel and alloy steel, with strength grade, thread length, head shape, nut and washer matching, coating, packing and inspection requirements confirmed before production. Zinc plating, black oxide, hot dip galvanizing and plain finish are available upon request for different project environments.
Quick Specs
What Buyers Should Know Before Sourcing Railway Track Bolts
Railway track bolts are not selected by diameter alone. Buyers should confirm rail joint design, fishplate thickness, hole size, head shape, shank design, thread pitch, nut style, washer type, strength grade, coating and vibration resistance requirement. If the project uses existing rail hardware, samples or a rail assembly drawing help reduce specification errors.
For non-standard head shapes, oval neck dimensions or special anti-rotation features, XZ Fastener can discuss custom fasteners according to drawings, samples or rail project schedules.
Procurement Notes
- Confirm whether the bolt is for rail joints, clips, base plates or repair kits.
- Match bolt grade with nut grade and washer hardness where specified.
- Check head clearance and anti-rotation design before placing bulk orders.
- For maintenance stock, provide package labels, part numbers and size groups.

Material and Grade Explanation
Railway track bolts usually require stable mechanical performance because rail joints and fastening assemblies are exposed to vibration, repeated loading and outdoor conditions. Grade 8.8 and 10.9 carbon or alloy steel bolts are common choices, while higher grades may be supplied when drawings require them. Buyers should confirm proof load, hardness and matching nut grade before production.
For mechanical performance checks, the guide to ISO 898-1 bolt mechanical properties helps buyers review tensile strength, proof load and hardness terms. Grade marking and label consistency are also important for rail maintenance stock, as discussed in fastener grade labeling.
Surface Finish Selection Guide
Indoor Storage and General Maintenance
Plain finish with oil, black oxide or phosphate treatment may be selected for controlled storage, maintenance kits or assemblies where the buyer specifies further treatment. Zinc plating is often used when a clean finish and moderate corrosion protection are required.
Outdoor Track and Corrosion Exposure
Hot dip galvanized track bolts can be considered for outdoor exposure, humid areas and long transport routes. Coating thickness should be checked against thread assembly and nut fit. Buyers can review the surface finish selection guide when selecting bolts, nuts and washers as a complete set.
Manufacturing and Quality Control
Railway track bolt production may include steel selection, cutting, heating or cold forming, head shaping, thread rolling, heat treatment, surface finishing, sorting and packing. Head geometry, shank diameter, thread accuracy and washer bearing surface should be controlled carefully because they affect fit in rail joints and fastening assemblies.
Buyers with special drawings can review how to order custom bolts from drawings or samples before sending an inquiry. Typical inspection can include thread gauges, caliper measurement, hardness checks, coating appearance, grade marking review and packing verification. Production process details are covered in how bolts are manufactured.
