Motorcycle fastener wholesale RFQ checklist
Use a supplier-catalog label or a clear part photo to start a bulk motorcycle fastener request. Then confirm the exact item, fitment and technical details before comparing written quotations.
Include the source label or reference photo, motorcycle make/model/year and market version, installation position, known dimensions or thread, quantity per item, packing request and destination. Ask the responsible seller to confirm every unknown field in writing.
Start with an identifiable reference
Four supplier-catalog fastener labels
These labels are copied from the supplied product catalogue as identification starting points. The catalogue excerpt does not establish a model-year fitment or list exact dimensions, thread, material, finish, MOQ, stock or price.
JDM colored motorcycle modification screws
Supplier label: 汽摩彩色改装螺丝 JDM
Identify the exact screw and installation position. Confirm dimensions, thread, material and available finish for the selected item.
Front-lamp screw reference
Supplier label: Honda 110 前照灯螺钉
Share the exact motorcycle year and market version, lamp mounting position and an original-part or location photo.
Locating-plate screw reference
Supplier label: JH70 定位板螺钉
Ask the seller to identify the matching plate, installation point, thread and dimensions for the requested variant.
Disc-brake rotor screw reference
Supplier label: 70/110/CG125/150 盘式制动盘螺钉
Treat the model range as a catalogue label only. Confirm the exact generation, market, rotor position and part reference before ordering.
Evidence boundary: a catalogue label or image helps identify what to ask about; it does not prove interchangeability, fitment, technical rating or an approved use.
COMPARE THE MEASUREMENT
Keep under-head length separate from overall length
The linked M6 reference diagram marks 12 mm below the head and 16 mm overall. The M8 diagram marks 20 mm below the head and 23 mm overall. Those measurements describe different boundaries; use the stated under-head dimension when identifying the requested reference, then confirm the selected option.
- M6 flanged star-socket bolt — 12 mm under-head reference
- Black M6 external-hex / star-socket bolt
- M8 socket-drive flanged bolt — 20 mm under-head reference
- Silver M6 drilled-head bolt
The black and drilled-head M6 references do not provide verified length or pitch values here. Do not borrow dimensions from another picture. Ask for thread pitch, drive size, flange dimensions and the required material or grade evidence for the intended installation. Multiple views or several pieces in a photo do not define the sales pack.
Prepare one comparable brief
What to include in a wholesale fastener RFQ
Send the information you already have. Mark unknowns as “please confirm” instead of filling them with a guess.
Catalog examples: the rear sprocket bolt set and rear sprocket mounting bolt set each list an MOQ of 1 set. Their records do not specify the number of bolts per set; the second does not confirm whether a separate sprocket lock plate is included. Send hub and fastener photos, thread measurements, quantity and destination, then ask for current MOQ, set contents and availability in writing before ordering.
Catalogue label, supplier reference, original/OE number if available, and one clear photo of the fastener and its location.
Make, model, model year, market/version, engine or generation code if known, and exact installation position.
Thread diameter and pitch, length, head type, material and surface finish only when measured or specified. Attach a drawing or a photo with a scale when available.
Quantity per reference, sample request, mixed-item plan, individual packing or labels, destination country/port and requested delivery window.
Review before approval
Ask for these points in the written quotation
Confirm the exact item
Match the label, photo, part position and seller reference on every quote line.
Resolve technical fields
Request the stated dimensions, thread, material, finish and compatibility evidence for that exact variant.
Compare order terms
Ask for MOQ, quantity basis, sample terms, packing, lead-time basis, price validity and inspection scope.
Check delivery and payment
Confirm destination, delivery responsibilities, named seller and payment beneficiary in the approved order documents.
Availability, specifications, MOQ and price are confirmed for the selected item in a written quotation. This guide is a sourcing checklist, not a product specification or installation instruction.
Fastener sourcing FAQ
Questions buyers often ask
Does a catalogue label guarantee that a fastener fits my motorcycle?
No. Confirm the exact year, market version, part position, dimensions and the seller's fitment evidence for the requested item.
Are the exact dimensions, materials and finishes published here?
No. The supplied catalogue labels do not provide those details for each reference. Request them from the responsible seller and keep the response with the quotation.
Can different fastener references be combined in a wholesale order?
List each reference and its quantity separately. Ask the seller to confirm availability, minimum quantities and whether the items can be combined.
What if I do not know the thread or dimensions?
Send a clear image of the original part beside a ruler, identify its mounting position and request a measurement check before approval.
