PRODUCT OVERVIEW

Product identification and RFQ basis

The website supports identification and inquiry. The written quotation, approved drawing or approved sample controls the order.

Metric shoulder screws — also called stripper bolts, stop bolts or equal-height screws — supplied to your size. Used in mold plates, slide assemblies, guide structures and fixtures wherever a precise shoulder has to locate while the thread clamps. Send the size designation, a drawing, or the dimensions off an existing screw and we come back with unit price, lead time and trade terms in writing — normally within one business day (Hong Kong time, Monday–Friday).

Your drawings stay confidential

Technical files are used to evaluate and fulfill your inquiry or order. They may be shared only with relevant manufacturing, inspection, logistics or service partners as needed. Send only files you are authorized to share. See our Privacy Policy. If your company requires an NDA, send the agreement or requirements to rfq@privleymold.com for review before sharing confidential files.

What to send us

Shoulder diameter (D) Required — Ø13, Ø16 and Ø20 are the most commonly requested; other diameters quoted on request
Shoulder length (L1) Required — this sets the working height, so measure it carefully
Thread size and pitch (M × P) Required
Head and drive Head diameter, head height and socket size, or just tell us the hex key that fits
Overall length Needed when it differs from the standard series
Property class Supplied as class 12.9 unless you specify otherwise
Surface finish Black oxide, zinc, or another treatment
Quantity Required — drives both unit price and freight

Don't have all of this? Send what you have. A photo of the existing screw next to a caliper is often enough to start, and we will tell you what else we need. Shoulder length and thread pitch are the two that must be right — everything else we can work around.

What we can supply

  • Standard metric shoulder screws in common shoulder diameters
  • Non-standard shoulder lengths and overall lengths
  • Replacement matching from a part number, drawing or sample
  • Mixed sizes and quantities for mold maintenance and BOM sourcing

Documentation

Material certificates, hardness results and dimensional inspection reports can be supplied with your order. Tell us what your quality system requires and we will confirm the scope — and any cost — in the quotation, so there are no surprises at goods-in.

What your quotation will state

Final specification, unit price, currency, lead time, packaging, freight and inspection scope — all in writing before you commit. Nothing is left to be worked out after the order.

IMPORT & DOCUMENTATION BASIS

US and European quotation checkpoints

These checkpoints reduce ambiguity before a formal quotation becomes an order. Exact responsibilities are set by the written quotation, delivery term, PI and final shipping documents.

UNITED STATES

Origin and import documents

Country-of-origin information and marking requirements are reviewed for the final item and packing as applicable. We do not publish a generic tariff rate or promise a fixed import duty on the product page.

EUROPEAN UNION / UK

Importer and customs data

Where the importer or customs process requires an EORI or other identifier, the buyer or importer can provide it later in the order or shipping workflow. The initial web RFQ should not contain unnecessary sensitive identifiers.

HS CLASSIFICATION

Final item basis

HS classification is reviewed against the final shipped product and declared on shipping documents where applicable. The quotation is not a binding customs classification or tax determination.

QUALITY & COMPLIANCE

Document-backed requests only

Material certificates, inspection reports, origin statements and product-specific regulatory information are confirmed only when applicable and supported for the quoted item. No blanket CE, RoHS or REACH certification is implied.

Buyer review point

Before payment, confirm the offered specification, quantity, unit system, destination, delivery basis, requested documents, tax or duty assumptions and beneficiary details on the written quotation and formal PI.

COMMERCIAL ORDER TERMS

International RFQ order basis

Product pricing, freight, import charges, payment route and delivery responsibilities are confirmed in the formal written quotation before an order is approved.

QUOTATION SCOPEConfirmed in writing

Product, specification, quantity, inspection, packaging and commercial basis are stated before approval.

COMBINED BOM REVIEWOne quotation

Multiple products, drawings or specifications can be reviewed together when practical.

ORDER APPROVALNo automatic checkout

An RFQ becomes an order only after the written quotation, specification and payment basis are accepted.

FREIGHT & IMPORT COSTSQuoted by destination

Freight, duties, taxes, customs clearance and destination charges are stated or allocated before approval.

Delivery basis

A quotation may use FCA China, DAP or another expressly stated term. Under DAP, import clearance, duties, taxes, brokerage and destination charges are normally paid by the buyer or consignee.

DDP requests

DDP is not the default. It applies only when the formal quotation expressly states DDP, identifies the destination and lists the included cost scope.

United States and other destinations

Freight is calculated from packed weight and dimensions, destination or postal code, route, carrier and service level. No free-shipping or fixed-duty assumption is made.

PAYMENT AFTER QUOTATION APPROVALVerified business payment routes

Payment instructions are issued only after the specification, quotation and formal PI have been reviewed.

PAYPAL BUSINESSUSD payment

PayPal may be offered for an approved quotation. The payer should verify the company and order reference before authorizing payment.

COMPANY TRANSFERFormal PI details only

A verified company receiving account may be used only when the exact beneficiary and currency-specific receiving details are stated on the formal PI. Account details are not published openly.

BENEFICIARY CONTROLIndependently verify changes

Never redirect payment based only on an email or messaging-app request. Reconfirm any change through the contact details published on this website.

Anti-fraud payment rule

PRIVLEY (HONG KONG) GLOBAL COMMERCE LIMITED does not instruct business customers to send company order funds to an unverified personal account. The legal company name, currency, amount, quotation reference and beneficiary details must match the formal PI.
