Shackles and Fasteners RFQ Checklist: How to Get Comparable Quotes

Author：Solidlink Hot：

A low unit price means little if two suppliers are quoting different materials, dimensions or inspection packages. For importers buying shackles alongside bolts, nuts and studs, a useful request for quotation separates product requirements from commercial terms—and makes exceptions visible before the purchase order is issued.

This checklist helps buyers build a clear RFQ. It is a procurement tool, not a lifting calculation or a substitute for the approved engineering specification.

1. Separate lifting hardware from general fasteners

Do not describe every steel connector as “heavy-duty hardware.” A rated lifting shackle and a general-purpose bolt are selected and accepted differently.

For a shackle, identify the intended application, required working load limit, configuration and applicable product requirements. For a fastener, specify the joint requirement, dimensional standard, thread and material/property class. A bolt strength marking is not a lifting WLL, and a threaded shackle pin is not a commodity bolt.

Browse SolidLink shackles and industrial fasteners as separate product groups, then create a separate RFQ line for each approved design.

2. Give every line a controlled specification

RFQ field	Shackle line	Bolt, nut or stud line
Identification	Part number, configuration, drawing revision	Part number, head/type, drawing revision
Dimensions	Body, pin, opening, internal length	Diameter, length, thread length, head dimensions
Performance	WLL and approved service conditions	Material/property class and joint requirements
Connection	Mating eye and sling interface	Thread series, pitch/TPI and tolerance class
Finish	Exact specified coating or finish	Finish, lubrication and mating-part requirements
Evidence	Required batch records and test scope	Required material/mechanical records
Acceptance	Critical features, sampling and disposition	Gauging, dimensions, finish and document checks

An RFQ may reference a drawing rather than repeat every dimension. The important point is that the supplier knows which document controls and must declare deviations.

For the two most common specification traps, see shackle pin diameter versus body size and metric versus UNC/UNF threads.

3. Keep material, strength and finish separate

“Stainless” does not identify a complete fastener specification. Likewise, “galvanized shackle” does not define a lifting rating.

List the material designation, required mechanical performance, finish and assembly requirements independently. If an alternative is allowed, ask for a separate quotation and a written comparison—not an unannounced substitution.

A frequent example is replacing coated carbon-steel bolts with stainless steel to improve corrosion resistance. Read A4-80 versus 8.8 bolts before treating similar tensile-strength labels as interchangeable specifications.

4. Define the documents before comparing prices

“Certificate included” is not a precise requirement. Ask what the document identifies, whether it contains actual test results, which batch it covers, and who issues it.

Use a separate document schedule if your customer requires material results, proof-load records, declarations or third-party witnessing. Do not assume that every commercial order includes every document or that one document satisfies all project requirements.

Our shackle certificate and traceability checklist explains how to connect the paperwork to the delivered goods.

5. Ask for visible commercial assumptions

For each quoted line, request quantity breaks, currency, unit of measure, packaging, delivery term with named place, payment terms, quotation validity and the event that starts the quoted lead time.

Also ask whether samples, inspection, special marking, document packages and export packing are included or separately priced. Avoid comparing a quotation for loose stock items with one for individually identified items and project-specific inspection.

MOQ and lead time should come from the supplier’s actual offer. Do not copy an estimate from a generic article into a purchase commitment.

6. Agree on acceptance and change control

Before production, identify the dimensions to inspect, the inspection method, the sampling arrangement and the process for nonconforming goods. State that changes to material, drawing, thread, finish, marking or subcontracted processes require approval where relevant to the order.

For repeat purchases, keep the approved drawing, reference sample, quotation and acceptance records together. A previous shipment that “worked” is not a controlled specification.

Frequently asked questions

Can I request a quote using only a photograph?

A photograph helps identify the general type, but it does not establish material, dimensions, thread or load rating. Use it to begin a discussion, then confirm a controlled specification.

Should all suppliers quote the same certificate package?

Yes, if the comparison assumes equivalent documentation. Otherwise show document differences and associated costs separately.

Is a sample enough to approve production?

A sample is useful, but it should be linked to a drawing, material requirements and an acceptance plan. Define how the production batch will be verified.
