CNC Fasteners

CNC Screws

Screws machined on CNC equipment in a range of materials, sizes and finishes, including machine screws and other varieties. Machining allows sizes and drive forms that are not held as standard stock, which is why these screws are used in applications such as aerospace where the specification is fixed by the design rather than by what is available.

  • Aluminium
  • Brass
  • Stainless steel

Product Overview

Screws machined on CNC equipment in a range of materials, sizes and finishes, including machine screws and other varieties. Machining allows sizes and drive forms that are not held as standard stock, which is why these screws are used in applications such as aerospace where the specification is fixed by the design rather than by what is available. Quality checks are applied before dispatch.

Key Benefits

  • Sizes, threads and drive forms made to the design, not selected from stock
  • Aluminium, brass and stainless steel to suit weight and corrosion requirements
  • Finishes specified with the order
  • Quality checked before packing
  • Price breaks available on larger quantities

Problems It Solves

  • Designs limited by the sizes a fastener stockist happens to carry
  • Obsolete screw specifications with no supply
  • Inconsistent finish and appearance across a visible fixing set
  • Long lead times on specials from distributors

Where It Is Used

Applications And Buyers

Application Scenarios

  • Aerospace assemblies where precision is critical
  • Instruments and equipment with non standard fixings
  • Restoration or maintenance of machines with obsolete screw sizes
  • Products where the screw head is visible and forms part of the design

Who It Is For

  • Aerospace and precision equipment manufacturers
  • Instrument makers
  • Maintenance engineers supporting older equipment
  • Product designers specifying a particular drive or head form

What Can Be Varied

  • Thread size, pitch and length
  • Head form and drive type
  • Material grade
  • Finish and coating
  • Quantity with volume price breaks

Compared With The Alternatives

Standard machine screwsStandard screws are far cheaper where they fit; machined screws exist for sizes, heads and materials that are not stocked.
Custom CNC boltsBolts carry the load in structural joints and are usually larger; screws cover the smaller fixings and a wider variety of head and drive forms.

Use Guide

  • Send the thread specification with the tolerance class, not only the nominal size
  • State the finish, because it changes the effective thread size
  • Send the annual quantity as well as the immediate order so volume pricing can be applied
  • Approve a sample where head appearance matters

Questions

Questions Buyers Ask About This Product

What affects the price of CNC screws?

Material, size, finish and above all quantity. Larger orders attract volume price breaks.

Which materials are available?

Aluminium, brass, stainless steel and others depending on the application.

Are volume discounts available?

Yes. Send the annual requirement as well as the first order and we will quote both.

Can you make aerospace specification screws?

Screws are machined to the specification you supply. Tell us the standard that applies and any documentation you need with delivery.

Are the screws inspected?

Yes, quality checks are carried out before dispatch.
