Stainless steel hex head screw mm 4×20 – code: VTSE4X20

Stainless steel hex head screw mm 4×20 – code VTSE4X20

La hex head stainless steel screw mm 4×20 (code VTSE4X20) is a fastening element designed for technical uses where neat assemblies, easy disassembly, and reliable hardware are required. The format with hexagonal head is a common choice in maintenance and system installation because it allows a stable grip with suitable tools and facilitates tightening and inspection operations.

Type

• Product: stainless steel screw
• Head: hexagonal
• Size: mm 4×20
• Product code: VTSE4X20

Identification and supply

To simplify warehouse management and spare part ordering, the screw is identified by:

• SKU: MOLIN00000095
• Supplier: F.LLI MOLINO SRL
• Supplier code: VTSE4X20

When reordering or comparing with a bill of materials, it is good practice to use the code VTSE4X20 to reduce the risk of confusion between similar sizes or different head variants.

Format and assembly logic

The combination hexagonal head + size 4×20 is typical of small hardware used in assemblies where a simple mechanical fastening that is easy to inspect and restore is desired. The hex head, compared to other shapes, is often chosen when:

• external tools (wrenches or suitable sockets) are preferred for tightening;
• a head easily recognizable even in technical spaces is wanted;
• periodic maintenance with repeated disassembly is performed.

Typical applications

This screw can be used in many situations where a stainless steel screw with the indicated hex head size is required. In technical fields, the most common applications include:

• Onboard maintenance: replacement of small parts on brackets, supports, and small assemblies.
• Plant engineering and accessories: fastening on components and supports related to hydraulic or mechanical installations, where choosing the correct screw is crucial for a neat assembly.
• General hardware: repairs and interventions on light structures or housings, when a hex head is desired for practical tightening.
• Spare parts: restocking screws in the workshop or toolbox, maintaining consistency with the 4×20 size already present in the system.

Final compatibility always depends on the type of hole, the required threading, and the fit with the nut/inserts or threads present in the part. In case of doubt, compare the screw with the one to be replaced.

Checks before installation

• Size check: make sure that the requested screw is actually 4×20 and that it matches the removed screw.
• Fit check: verify the match with the existing thread (threaded hole, nut, or insert).
• Maneuvering space: assess the accessibility for the tool on the hex head, especially in technical compartments.

Best practices in nautical/plant engineering

In onboard and plant applications, it is advisable to maintain consistency between the materials of the small parts and those of the coupled components, following the manufacturer's instructions. If the assembly involves washers, nuts, or other elements, select accessories compatible with the size and the intended assembly logic.

When to ask for support

If you need to replace an existing screw but are not sure of the correct variant (for example, due to threading or standard), it is useful to have available:

• photos of the original screw and the mounting seat;
• information about the component on which it is installed;
• any references from the bill of materials or technical manual.

This way it is easier to confirm that the VTSE4X20 is the correct choice for your intervention.

Summary

STAINLESS STEEL HEX HEAD SCREW MM 4×20 – CODE: VTSE4X20: essential small parts for maintenance and technical assemblies, with clear identification for reorder and spare parts management.
