Custom metal screws
manufacturer.
DONGGUAN ZUFEK PRECISION CO., LTD.
Manufacturing non-standard metal screws in Dalang, Dongguan since 2005. From tooling and samples to repeat production, built around your approved drawing.
Company background and sample planning
Beyond the standard catalog.
Explore custom screw configurations. Final geometry, material and manufacturing feasibility are reviewed against your specification.

Shoulder & Step Screws ↗
A head, a locating shoulder and a threaded section combine fastening with controlled spacing or movement.

Security & Tamper-Resistant Screws ↗
Special drive interfaces help restrict casual access while allowing an approved service tool to operate the screw.

Hollow & Through-Hole Screws ↗
An axial bore creates a passage through a threaded component for an application-specific routing or flow requirement.

Custom Flange Screws ↗
An integral flange provides a drawing-defined bearing footprint without a separately handled washer.

Knurled Thumb & Adjustment Screws ↗
A grip-oriented head supports manual adjustment, with optional tool drive for the specified assembly method.

Custom Set Screws & Grub Screws ↗
Headless threaded components transfer a locating or clamping action through a specified tip.

Automotive Components ↗
Custom threaded components for brackets, equipment modules and other drawing-defined automotive component assemblies.

Industrial Automation ↗
Shoulder, step and adjustment fasteners for guided mechanisms, positioning stations and automation equipment.

Electronics & Optical Equipment ↗
Drawing-defined fasteners for compact housings, optical adjustment mechanisms and precision module assemblies.

Energy, Charging & Storage Equipment ↗
Custom fastening and connection geometries for equipment housings, brackets, routing features and electrical interface components.

The details make
the difference.
Head geometry. Thread requirements. A critical shoulder dimension. Your application starts with details that a standard catalog may not cover.

Agree feasibility, quotation and sample requirements before proceeding.

Carbon & Alloy Steel ↗
A practical choice for drawing-defined fasteners where the required mechanical class, wear behavior and surface protection can be specified together.

SUS304 & SUS316 Stainless Steel ↗
Austenitic stainless choices for parts where corrosion exposure, surface condition and the specified fastener strength class need to be considered together.

Aluminum Alloys ↗
Lightweight metal options for custom threaded parts where the alloy, temper, engagement and surface requirements can be engineered for the application.

Copper ↗
A material family considered where electrical or thermal function is important alongside the geometry and mechanical acceptance of the custom component.

Brass ↗
Copper-zinc alloys can be useful for drawing-specific machined threaded components where machining behavior, contact conditions and the selected alloy composition fit the application.

Titanium & Titanium Alloys ↗
Titanium grades are considered where mass, corrosion exposure and required mechanical properties justify a grade-specific manufacturing and verification plan.
CCD Vision & Dimensional Inspection
Non-contact optical checks for screw length, head diameter and visible stepped profiles, combined with the gauges and tests required by the drawing.

What to include in a custom screw RFQ
A useful quotation starts with a clear specification. A drawing is the best starting point, but a sample, sketch or assembly description can also help define the next questions.
Read technical guide →A practical guide to shoulder screw drawings
A shoulder screw drawing needs separate bore-fit, axial-stack, thread and final-surface requirements. Check both tolerance limits before sample approval.
Read technical guide →Five questions before specifying a captive screw
Specify a captive screw with its panel, retainer and mating thread. Review installation, released travel and tightened engagement as separate conditions.
