Many fastener price disputes start with an incomplete RFQ. A buyer asks for “M12 bolts, zinc plated, 10,000 pcs,” then later adds grade, standard, thread length, certificate, packing, or delivery terms. The first price looked low because the real requirement was not fully visible.

A good RFQ does more than get a quote. It helps both sides remove guesswork.

Why Fastener Prices Change

Fastener pricing is shaped by more than size and quantity. Material, manufacturing route, finish, testing, and packing all affect cost.

For common items, buyers can compare against стандартные крепления before requesting special production.

Build a Clear RFQ Before Asking for Price

Core Technical Details

Полезный RFQ должен включать:

• Название продукта и стандарт
• Диаметр, длина, шаг и длина резьбы
• Материал и класс прочности
• Surface finish and color requirement
• Nut and washer match, if needed
• Количество по каждому размеру
• Drawing or sample photo for non-standard parts
• Packing, labeling, and pallet requirement
• Certificate and inspection report requirement

If a part is made to drawing, send the drawing at the beginning. For unusual dimensions or special heads, нестандартные крепления usually need more review than catalog items.

Cost Saving Without Creating Trouble

Choose Standard Sizes Where Possible

Standard sizes reduce tooling, setup time, and production risk. If the application allows it, avoid special lengths that differ only slightly from available sizes.

Match Finish to Environment

Do not overpay for heavy coatings in dry indoor use. Do not under-specify coating for outdoor or coastal use. For corrosion-related selection, review крепеж с покрытием.

Avoid Unsafe Substitutions

Switching from one standard to another can save money, but only after checking dimensions, strength, thread fit, and marking. The Руководство по стандартам крепежа DIN и ISO is useful when comparing metric specifications.

Распространенные ошибки RFQ

• Comparing quotes with different materials or finishes
• Asking for certificates after price confirmation
• Ignoring carton weight and freight cost
• Mixing inch and metric thread descriptions
• Replacing one grade with another without engineering approval
• Forgetting nuts and washers in assembly orders
