Non-standard screws

As a vertically integrated manufacturer, we specialize in engineering mission-critical non-standard screws to your exact specifications. From prototype to mass production, our in-house capabilities allow full customization of dimensions, materials, and performance characteristics. Leverage our ISO-certified manufacturing ecosystem to solve unique fastening challenges with screws that simply don’t exist off-the-shelf.

Have you encountered any of these problems?

The quality is not up to standard

The strength of screws is nominal or easy to break

No certification of compliance

Special shaped parts have been rejected many times

Only standard parts can be made

suppliers can not undertake non-standard customization requirements

You Can't do extreme structures

Special shaped parts have been rejected many times

Lead time due to insufficient production capacity

Critical delivery delays in supplier capacity

Rejection of special materials

Nobody takes orders for titanium/alloy special materials

Reject mass production after proofing

The sample passed but the batch production was stopped

Breach of trust after delay in payment

Delay and prevarication after payment of an order

Our solution

Mass-produce special-shaped fasteners with 5x over-threaded heads via multi-station automation. Batch-standard prototyping eliminates “sample assassins.” Triple QC + SGS/ROHS certs with H.E./salt spray tests. Urgent non-standard orders fulfilled. Transparent risk management. 20+ materials (C17200/Ti/etc.) with certs.

Technology Breakthrough

Multi-station machine for mass production of special-shaped parts with 5 times over-threaded head

Thinking of mass production

Proofing is to produce according to batch standard and eliminate“Sample assassins”

Quality Control System

Three total + SGS/ROHS certification, support hydrogen embrittlement/salt spray 12 test

Production capacity guarantee

Large-scale production of non-standard parts, urgent single response does not jump ticket

Cooperation in good faith

Be upfront about risks and don't take promises you can't make

Special material covering

C17200 beryllium copper/A286/titanium etc. 20 + special materials, with material report

Quality Control Process for Raw Materials

Implements a rigorous 4-stage raw material validation protocol to ensure manufacturing integrity

Application scenarios

Our certificate

Our Happy Clients!

We asked a lot of suppliers, no supplier can produce cold heading A286 screws, although the shape is the same as the conventional, but the material is too special. We are very lucky to find Worldcom, they can solve this special material of cold heading production, we have received the goods, perfectly meet our requirements, a great cooperation.

they are very professional, according to the design of the drawings to see the subsequent assembly of the hidden danger, for us to optimize the design, to avoid our loss.

Before we found Worldcom, we had a bad deal. The original supplier hadn’t solved our appearance and size problems. Worldcom solved them and provided us with valuable advice, tell us where we can optimize it so that it’s cost-effective and doesn’t interfere with usage. They’re experts in that area.”
