Metric Screws ø4.25 x 9.2mm Flat Head

Precision Screws for Those Who Care About Every Detail of Assembly

In the preparation of a slot car or any modelling project, small fastening elements carry more weight than they seem. A poorly sized screw can compromise the rigidity of the chassis, create unwanted play, or hinder quick disassembly in the pits. The BRM-S132B2 Metric Screw ø4.25 x 9.2mm Flat Head meets this need with specific and reliable measurements.

Main Features

• Diameter: ø4.25 mm
• Length: 9.2 mm
• Head type: flat (countersunk), allowing for a flush finish with the mounting surface
• Reference: BRM-S132B2

Function and Performance

The flat head —also known as countersunk— is the usual choice when the screw needs to be flush with the part, without protruding. This is particularly useful in areas where the low profile of the component is critical: chassis bottoms, body closures, or mounting anchors. By not creating protrusions, interference with other parts is avoided, resulting in a more refined finish.

Assembly and Preparation

For proper tightening, it is important to work with the screwdriver that matches the size of the slot or star of the head, applying uniform pressure without forcing. Keeping these screws well sorted —by diameter and length— saves time at the workbench and avoids confusion during assembly or in a racing session.

Frequently Asked Questions

What is the difference between a flat-head screw and a cylindrical-head screw?

The flat head is designed to be flush with the surface once tightened, thanks to the countersunk angle of its profile. The cylindrical head, on the other hand, protrudes above the surface. The choice depends on the available space and whether that low profile is needed.

Can I use this screw in different brands or chassis?

As long as the destination hole has dimensions compatible with ø4.25 x 9.2mm, yes. We recommend checking the tolerances of the chassis or component before proceeding with assembly.

How many units are included in the pack?

The information provided by the manufacturer does not specify the number of units per package. Please check the updated commercial sheet in our store for this specific data.

Is any special tool required for assembly?

No special tool is required, but it is important to use the screwdriver of the exact size and type that corresponds to the head of this screw to avoid damaging the slot or the component itself.

The BRM-S132B2 is a flat-head metric screw measuring ø4.25 x 9.2mm, designed for precise and flush fixing in slot car chassis assembly, modelmaking and hobby projects. A reliable small part for builders who demand accuracy in every detail.
