Custom Fasteners Manufactured to Your Specification
We manufacture and supply custom fasteners to customer drawings and specifications, with control over threads, head forms, lengths, materials, finishes, inspection, packaging and repeat production.
The Challenge
Standard fasteners are designed for broad applications, but many manufactured products require dimensions, materials or features that cannot be sourced reliably from a catalogue.
Non-standard thread lengths, head forms, shoulders, recesses, cross holes, points, material grades and finishes can all be critical to assembly and performance.
For OEMs, the challenge is not only producing the first acceptable batch. The fastener must then remain consistent across repeat production, with dependable availability and documented requirements.
The requirement is therefore for a manufacturing partner capable of turning a drawing or sample into a controlled, repeatable component supply programme.
The Solution
Darian manufactures and supplies bespoke fasteners for industrial and OEM applications, from modified standard forms to completely customer-specific parts.
We review your drawing, sample or specification together with thread details, dimensions, head and drive requirements, material, finish, quantities, tolerances and inspection requirements before determining the appropriate manufacturing route.
Tooling and samples can be approved before volume production, with manufacture, quality control, documentation, packaging and delivery managed through one accountable Darian contact.
Our established international manufacturing capability gives customers access to competitive production while Darian remains responsible for ensuring the finished fastener is produced and supplied against the agreed requirements.
Custom Screws, Bolts, Studs and Special Fasteners
We manufacture customer-specific fasteners across a broad range of forms, from familiar threaded components with modified dimensions through to fully bespoke parts.
Typical requirements can include:
- Custom screws
- Special bolts
- Threaded studs
- Shoulder fasteners
- Special nuts
- Threaded pins
- Metric and imperial threads
- Special head and drive forms
- Customer-specific materials and finishes
- Fasteners manufactured to drawing
Components can be manufactured against agreed drawings, samples or specifications, with dimensional inspection, material documentation, traceability, surface-finish requirements and customer-specific packaging incorporated where required.
Special Fasteners Made to Drawing
Not every assembly can be designed around an off-the-shelf fastener.
Darian can manufacture custom fasteners where thread, head form, shoulder, length, drive, material, finish or other geometry needs to differ from a standard part.
We can work from an existing engineering drawing, specification or physical sample to establish the manufacturing requirement and approval process.
Send us your drawing, sample or specification and we can assess the requirement.
Why Use Custom Fasteners?
Custom fasteners allow the fastening component to be designed around the product rather than forcing the product around a standard catalogue item. This can improve assembly, reduce additional parts and maintain customer-specific material or finish requirements.
Custom Fasteners for Industrial and OEM Applications
We manufacture special fasteners for use across a range of manufactured products and assemblies.
Requirements may come from sectors including:
- General engineering
- Agricultural machinery
- Automotive and transport equipment
- Electrical and electronic products
- Pumps and fluid-control equipment
- HVAC equipment
- Construction products
- Specialist machinery and OEM assemblies
