Common Questions
What Should We Send for a Quotation?
Send your drawing, BOM or a short description. Identify the product, material or UNS, dimensions or thread, quantity and any applicable standards. Add inspection, document and delivery requirements when they are already defined.
Can You Review a Drawing-Based Fastener?
Yes. Send the latest drawing revision with the alloy, quantity and applicable requirements. We review the requested geometry, material condition, manufacturing route and inspection scope before confirming what can be quoted.
What if Our Drawing Is Incomplete?
Share the information you have, such as the part type, dimensions, alloy, quantity, photographs or an existing specification. We will identify the points that still need agreement. Photographs and illustrative models do not establish dimensions, tolerances, material or performance requirements.
How Should Standards Be Specified?
List the dimensional standard, material specification, finished-product requirements and inspection or documentation requirements separately. Include the applicable revision when it is controlled by your project.
What Is Included with Every Delivery?
Every BYBOLT delivery includes an MTC / EN 10204 3.1 certificate, heat-number traceability and mechanical testing. Threaded products include sampled GO / NO-GO gauging. Test methods and acceptance criteria follow the agreed specification; PMI, third-party inspection and additional records are agreed separately.
Do You Manufacture Custom Fasteners?
Our factory supports custom alloy fastener manufacturing. Product, material, manufacturing route and inspection/documentation requirements are agreed for each order. If your purchasing process requires a facility assessment, include that requirement for review.
