Product Selection

Compare threaded fasteners by function, drawing interfaces, material and delivered condition. These product type illustrations help organise an enquiry; the final geometry and supply scope must follow the approved drawing and written quotation.

Hex Head Bolts product type illustration

Hex Head Bolts

A hex head bolt provides an externally threaded fastening element with a hexagonal driving head. The head dimensions, shank length and threaded portion define the ordered form. Its mating connection must be specified rather than assumed from the nominal diameter. Material, required property designation and coating belong to the actual item specification; head appearance alone does not establish mechanical performance. Product type illustration. Final geometry follows the approved drawing. State the quantity, material, mating interfaces and delivered condition when requesting a manufacturer, supplier or factory quotation. Open the product detail to review the enquiry checklist.

Double End Threaded Studs product type illustration

Double End Threaded Studs

A double end threaded stud has external threads at both ends and no conventional bolt head. The two thread lengths, any unthreaded middle section and the required end details must be defined. A fully threaded rod is a different form and should not be substituted without agreement. Identify how each end connects to the assembly and which matching nuts or other components belong to the supply. Product type illustration. Final geometry follows the approved drawing. State the quantity, material, mating interfaces and delivered condition when requesting a manufacturer, supplier or factory quotation. Open the product detail to review the enquiry checklist.

Hexagon Nuts product type illustration

Hexagon Nuts

A hexagon nut provides an internally threaded connection with hexagonal wrenching surfaces. Its thread, height and bearing-face requirements should match the specified joint. A matching nominal diameter does not establish compatibility with every bolt or stud, and a plain nut is distinct from a locking-nut configuration. Define the required designation, material condition and any coating or marking requirements before ordering. Product type illustration. Final geometry follows the approved drawing. State the quantity, material, mating interfaces and delivered condition when requesting a manufacturer, supplier or factory quotation. Open the product detail to review the enquiry checklist.

Machine Screws product type illustration

Machine Screws

A machine screw is an externally threaded fastener with a defined head and drive form for a specified mating thread. The head profile affects the joint surface and access for installation. A countersunk, pan or socket head should not be substituted solely because the thread is similar. Keep the screw length definition, thread details and finish with the selected head form in the enquiry. Product type illustration. Final geometry follows the approved drawing. State the quantity, material, mating interfaces and delivered condition when requesting a manufacturer, supplier or factory quotation. Open the product detail to review the enquiry checklist.

Enquiry with Foundry Queen

Review the installation interfaces, manufacturing route and inspection scope before comparing quotations for threaded fasteners. Foundry Queen enquiries can include the drawing revision, quantities, destination and packaging requirements. A supplier or exporter should state the accepted material, delivered condition, machining operations and documentation in the written quotation. Price comparisons are meaningful only when the same scope is used. Images on this page are product type illustrations and do not establish an approved model, rating, certification or available stock.

Hex Head Bolts Product Introduction

A hex head bolt provides an externally threaded fastening element with a hexagonal driving head. The head dimensions, shank length and threaded portion define the ordered form. Its mating connection must be specified rather than assumed from the nominal diameter. Material, required property designation and coating belong to the actual item specification; head appearance alone does not establish mechanical performance.

Configuration and supply scope

Specify the complete thread designation, dimensions, material and required condition. A nominal diameter alone does not define thread pitch, fit or mechanical requirements. Keep the selected designation and any drawing together when comparing quotations.

Foundry Queen enquiries should include the selected component drawing, quantity and the required delivered condition. Identify the features to be machined, the accessories to be included and the documents needed with the order. This product-family description does not define a stocked model, a universal replacement or an approved performance rating.

Double End Threaded Studs

A double end threaded stud has external threads at both ends and no conventional bolt head. The two thread lengths, any unthreaded middle section and the required end details must be defined. A fully threaded rod is a different form and should not be substituted without agreement.

Comparing a manufacturer, supplier or factory quotation

Use the same drawing revision, material requirement, quantity and delivered condition for each enquiry. The factory should identify the process route, machining interfaces, inspection scope and packaging basis. A custom quotation should distinguish tooling, samples, production parts and optional work. Foundry Queen can organise a clear purchasing enquiry without treating an illustrative image as a confirmed specification.

Exporter scope and price comparison

Identify the destination, shipping terms, packaging requirements and requested documents before comparing an exporter offer. Price should be assessed against the accepted technical scope, including any tooling, machining, finish, inspection or delivery assumptions. Confirm changes in writing before an order is placed. No fixed product price, certification or performance rating is implied by this guide.
