Hex head screw mm 4×30 – code: VTE4X30

Hex head screw 4×30 (code VTE4X30)

La hex head screw 4×30 (code VTE4X30) is a fastening element designed for use in hardware and for typical work in the’plant engineering, where practical tightening and a head easily operated with common tools are needed. In the technical field – such as maintenance, outfitting, and interventions on onboard systems – a hex head screw is often chosen for its simple handling during assembly and disassembly, especially when working in operational spaces or on components requiring periodic checks.

Hex head: practical tightening

La hexagonal head allows direct tightening action with wrenches and sockets, making the screw suitable for assembly operations where simple torque control is desired (depending on the assembly and available tools). It is a common solution when an external and easily accessible grip point is preferred.

Size 4×30

The size 4×30 identifies the screw based on its nominal dimensions. This information is particularly useful for:

• selecting the correct fastener during design or replacement;
• maintaining consistency with components already present on systems or structures;
• reducing procurement errors when managing multiple sizes in stock.

Product identification and supply

For orderly material management, the screw is tracked with:

• Product code: VTE4X30
• SKU: MOLIN00000020
• Supplier: F.LLI MOLINO SRL

This information is useful for requests for quotes, reorders, and alignment with technical documentation or maintenance lists.

Typical applications (nautical and plant engineering)

Without entering specific compatibility (which depends on the project and coupled materials), it can be considered for:

• bracket assemblies and small supports;
• component fastenings on panels or technical structures, where an easily reachable head is useful;
• routine maintenance and replacements, when restoring existing fastenings with the same size;
• outfitting and retrofit on systems and accessories, where the hex head facilitates quick interventions.

The choice of the correct screw always depends on the context: component material, presence of vibrations, usage environment, and type of coupling. In case of doubt, it is advisable to verify the required size and the configuration of the existing fastening.

Usage and practical notes

Measurement check before purchase

For a correct replacement, it is important to verify that the requested screw matches the size 4×30 and that it is consistent with the existing fastening (for example, in terms of effective length and dimensions). If it is a new assembly, it is advisable to check compatibility with the holes and the coupling elements specified in the design.

Good installation practices

• Ensure that the contact surfaces are clean and properly mated.
• Use appropriate tools to avoid damaging the head.
• During maintenance, replace the screw if there are obvious signs of wear or deformation.

For specific plant requirements or particular applications, it is advisable to refer to the instructions of your technician or internal maintenance procedures.
