What Buyers Should Know Before Sourcing 35CrMo Alloy Steel Fasteners
For export sourcing, the most important details are not only size and quantity. Buyers should also confirm material grade, heat treatment requirement, mechanical performance, thread tolerance, finish, packing method, and destination documents. 35CrMo alloy steel is often specified when the fastener must handle tightening load, vibration, and repeated stress.
If your part has non-standard head dimensions, fine thread, shoulder sections, drilled holes, extended length, or special marking, XZ Fastener can review custom fasteners based on drawings, samples, or clear technical descriptions.

Material and Grade Explanation
35CrMo is a chromium-molybdenum alloy steel often used for mechanical parts and fasteners that require better hardenability and strength than ordinary carbon steel. With suitable heat treatment, it can support demanding fastening positions in equipment, tooling, and industrial maintenance projects.
International buyers should confirm whether the purchase order accepts 35CrMo by Chinese standard or requires an equivalent material. Chemical composition, mechanical properties, hardness range, and inspection method should be stated when material substitution is not allowed.
Surface Finish Selection Guide
- Plain oil: common for machined or heat treated parts that need short-term storage protection.
- Black oxide: suitable for indoor machinery fasteners where a dark finish is preferred.
- Zinc plated: used for general corrosion protection and clean appearance in dry environments.
- Phosphate: selected for oil retention, controlled friction, or assembly requirements.
- Geomet or Dacromet: considered when improved corrosion resistance is needed for alloy steel parts.
- Hot dip galvanized: used for outdoor steel structures, with thread fit reviewed before production.
Manufacturing and Quality Control
Production Review
Production planning covers material confirmation, drawing review, tooling check, forming or machining method, thread processing, heat treatment, finishing, inspection, and export packing. For 35CrMo orders, heat treatment and dimensional control should be reviewed early because they affect strength and thread fit.
For orders requiring traceable material, buyers can discuss raw material inspection, batch separation, and document requirements before production starts.
Inspection Points
Common checks include size measurement, thread gauge inspection, head dimensions, hardness, tensile performance when required, coating thickness, surface appearance, marking, quantity, and packing labels. Inspection content can be adjusted according to order risk and buyer requirement.

- Attach drawings for non-standard dimensions, special tolerances, or controlled markings.
- Confirm material grade, equivalent material rules, heat treatment, and finish.
- State packaging method, label format, carton weight, pallet requirement, and destination.
- List inspection requirements, reports, or third-party checking before quotation.
Export Packing and Documents
Export orders can require different packing and paperwork depending on destination, buyer system, and shipping method. Common information includes invoice details, packing list, shipping mark, carton dimensions, pallet information, and product description. XZ Fastener can discuss export shipping documents before shipment planning.

FAQ
Can XZ Fastener export 35CrMo alloy steel fasteners by mixed sizes?
Yes. Mixed-size orders can be reviewed according to the buyer’s size list, quantities, packing method, and label requirement. Separate line items help confirm production and packing more accurately.
What documents are usually needed for exporting alloy steel fasteners?
Common documents include commercial invoice, packing list, bill of lading, and other documents requested by the buyer or destination market. Inspection or material documents should be confirmed before order placement.
Can 35CrMo fasteners be supplied with heat treatment inspection?
Heat treatment inspection such as hardness checks and other agreed tests can be discussed before production. Buyers should provide the required hardness range, strength class, or testing standard.
Which finish is better for export orders, black oxide or zinc plated?
Black oxide is often used for indoor machinery parts, while zinc plating provides general corrosion protection and a cleaner appearance. The final choice depends on storage, working environment, assembly torque, and buyer preference.
Can XZ Fastener make 35CrMo fasteners according to drawings?
Drawing-based parts can be reviewed according to order requirement. Please provide drawings with dimensions, tolerances, material, finish, heat treatment, inspection requirements, and quantity.
How can buyers reduce quotation delays?
