Rail Joint Fastening Supply for Project Buyers
fishplate bolts manufacturer
XZ Fastener manufactures fishplate bolts for rail joint assemblies, maintenance kits and track fastening projects where bolt fit and repeatable clamping force matter. Fishplate bolts can be supplied as oval neck, round head, square neck, hex head or drawing-based designs according to rail plate holes and project drawings. Materials include carbon steel, medium carbon steel and alloy steel, with Grade 8.8, 10.9 and other grades available upon request. Plain, black oxide, zinc plated and hot dip galvanized finishes can be selected for different storage, installation and outdoor service conditions.
Quick Specs
What Buyers Should Know Before Sourcing Fishplate Bolts
Fishplate bolts connect rail joint bars and must match the hole shape, plate thickness, rail section and installation method. Buyers should confirm head type, neck geometry, shank diameter, thread length, nut style, washer requirement and mechanical grade before placing an order. When a fishplate bolt is not a standard catalogue item, XZ Fastener can discuss custom fasteners based on drawings, samples or measured dimensions.
For rail maintenance programs, the most common risk is mixing similar-looking bolts with different neck shapes, lengths or grades. Clear drawing numbers, packing labels and inspection requirements help reduce wrong-part delivery and speed up site sorting.
Buyer Confirmation Points
- Confirm rail joint type, fishplate thickness and hole diameter.
- Specify round head, oval neck, square neck, hex head or special head design.
- List nut, washer and set-packing requirements separately.
- Confirm coating, grade marking, carton label and pallet label requirements.
Common Purchasing Descriptions
Fishplate bolts may be requested as rail joint bolts, track bolts, oval neck fish bolts, round head fishplate bolts, square neck rail bolts, carbon steel fish bolts, Grade 8.8 rail joint bolts, black oxide fishplate bolts or hot dip galvanized fishplate bolts.

Material and Grade Explanation
Fishplate bolts are commonly produced from carbon steel or alloy steel, then heat treated to reach the required mechanical grade. Grade 8.8 is frequently used for many rail joint applications, while Grade 10.9 or higher grades may be requested for heavier duty assemblies. Buyers can review ISO 898-1 bolt mechanical properties when checking tensile strength, proof load, hardness and elongation requirements.
Grade marking, thread quality and dimensional control should be checked together before shipment. For mixed rail fastener orders, XZ Fastener recommends confirming every line by size, grade, finish and drawing number. The guide on fastener grade labeling gives useful points for reducing wrong-spec delivery.
Surface Finish Selection Guide
Plain and oil-coated fishplate bolts are used where storage and installation conditions are controlled. Black oxide offers a dark appearance with light oil protection. Zinc plating is suitable for general industrial use, while hot dip galvanizing is commonly selected for outdoor railway environments that require stronger corrosion resistance.
When bolts, nuts and washers are supplied as a set, the finish should be checked as a complete assembly. Buyers can compare coating choices in the surface finish selection guide, including how corrosion protection, thread fit and appearance requirements affect the final order.
Manufacturing and Quality Control
Fishplate bolt manufacturing may include steel selection, cutting, heating or cold forming, head and neck forming, thread rolling, heat treatment, surface treatment, sorting and packing. The neck profile, shank diameter and thread length require careful dimensional control because they directly affect fit with rail joint plates and nuts.
For non-standard fishplate bolts, buyers can prepare a clearer RFQ by following the article on how to order custom bolts from drawings or samples. Buyers who want to understand the main production flow can also review how bolts are manufactured before confirming inspection points.
