Metric Screws ø3.8 x 7.2mm Cone Head

Precision in every thread: metric screw ø3.8 x 7.2 mm with countersunk head

In the preparation of any modelling or slot project, small fastening elements are as important as the more eye-catching parts. This metric screw with a countersunk head measuring ø3.8 x 7.2 mm (ref. BRM-S134A1) meets the need for the correct fasteners when assembly demands it.

Main features

• Diameter: ø3.8 mm
• Length: 7.2 mm
• Head type: countersunk, for a flush fit that does not interfere with adjacent surfaces
• Reference: BRM-S134A1

Function and performance

The countersunk head of this screw allows it to be recessed into the material, achieving a low profile that prevents mechanical interference and improves the visual finish of the assembly. It is the type of detail that makes the difference between a rushed assembly and a well-executed job.

Assembly and preparation

Before inserting the screw, it is advisable to properly prepare the seating to ensure a clean fit for the countersunk head. An appropriate countersink ensures that the head is flush without stressing the surrounding material. Use tools of the correct size to avoid damaging the tightening slot and respect the recommended torque for the material you are working on.

Frequently asked questions

What advantage does the countersunk head offer over other types of heads?

The countersunk head sits flush with the surface once tightened, eliminating protrusions that could interfere with moving parts or the visual finish of the assembly. It is especially useful when space is limited or when a clean profile is desired.

What materials is this screw compatible with?

We do not have specific manufacturer information regarding the material of this screw. We recommend contacting us if you need that specific information before placing your order.

Is it possible to reuse this screw multiple times?

It depends on the manufacturing material and the tightening force applied with each use. As a general rule in precision fasteners for modelling, it is advisable to inspect the thread before each assembly and replace the part if wear is detected.

Does it come in a pack or is it sold individually?
