RootReach Global helps overseas buyers identify and coordinate with fastener suppliers in Yongnian, Handan. We work from your standard, drawing and commercial requirements. We are a sourcing and trading business, not the manufacturer.

PRODUCT SCOPE
Choose the family on your drawing or specification. Each enquiry link opens a tailored brief; leave unknown fields marked “to be confirmed”.

Request custom and special fastenersThese are enquiry categories, not stock or certification claims. A matching name or photograph does not establish material, grade, dimensions or suitability. Confirm the specification before accepting a quotation.
REQUEST FOR QUOTATION
Availability, minimum order quantity, samples, certifications, lead time, payment and shipping terms must be confirmed for the selected product, supplier and order.
BEFORE YOU COMPARE PRICES
Use one enquiry line for each size and finish. Start with the information you have, and mark gaps as “to be confirmed”. Ask suppliers to identify deviations rather than silently substitute a different specification.
This checklist helps prepare an enquiry; it is not an engineering selection or a compliance certificate. The buyer must confirm the specification and suitability for the intended application. Product and order requirements remain subject to written confirmation.
HAVE A PHOTO, NOT A COMPLETE SPECIFICATION?
Yes—as a starting reference. Send labelled photographs, the measurements you have, intended use, quantity and destination. Leave unknown specifications open for clarification. A photograph is not enough to approve material, property class, thread tolerance, finish or suitability.
Illustrative enquiry, not a customer case: “F01: replacement fastener for an existing assembly. Photos F01-overall and F01-head attached. Quantity: 500 pieces. Destination: Dubai, UAE. Material, grade, thread pitch and finish: to be confirmed. Please list missing information before quoting a replacement.”
This starts a clarification conversation; it is not a complete specification or a commitment that a replacement is available.
Attach images in your email or WhatsApp after preparing the brief. RootReach coordinates the enquiry; the buyer and proposed supplier must resolve specifications, evidence and suitability before approval. Guidance basis: the fastener specification checklist on this page, not a supplier technical certificate.
SOURCING ROLE
We organize the enquiry, compare supplier responses, coordinate samples and document the agreed specification. Inspection and export coordination can be arranged when they are included in the quotation and order scope.
BUYER QUESTIONS
Send the product type, standard number or dimensioned drawing, material or property class, thread size, length, surface finish, quantity, packaging requirement and destination. Add the required inspection scope or documents when applicable.
No. Availability, minimum order quantity, samples, certifications, lead time and commercial terms are confirmed for the selected product, supplier and order before a quotation is accepted.
Yes, as an initial reference. Include dimensions, visible markings, the intended use and any available drawing or standard. Mark unknown requirements as to be confirmed. A photograph alone does not verify material, property class, thread tolerance or coating specification; these must be resolved before order approval.
Ask the supplier to quote the requested specification first and list any alternative separately, with its standard or drawing, material, property class, dimensions and finish. Do not treat an alternative as approved until the buyer has reviewed the differences and confirmed acceptance in writing.
Send separate, clearly labelled views of the whole item, its head or drive, readable markings, thread and end. Include available measurements with units and label the images with the enquiry line number. Add intended use, quantity and destination. Keep unknown material, grade, thread and finish requirements open for clarification; photos are a starting reference, not approval of a replacement.
Contact Yang Aoxin (杨奥鑫). Attach a drawing or standard reference whenever possible. The email link opens a fill-in RFQ; leave unknown fields blank for confirmation.

SAMPLE APPROVAL & SUPPORTING EVIDENCE
Identify the standard or drawing revision, dimensions, thread, material and grade, and finish. Record the sample reference and agreed inspection criteria. Keep proposed equivalents separate until the buyer approves them.
Request dimensional inspection results and the material or finish documents required by your brief. Check that their references match the proposed item and agreed order scope.
