OEM M40x3 mm stainless steel cylinder head screws, 10-piece set. Corrosion-resistant fasteners for RC models, electronics, and workshop assemblies requiring long-term reliability and a flush finish.
These OEM cylinder head screws are precision fasteners designed for secure, corrosion-resistant fastening in demanding applications. The M3x40 mm dimensions and stainless steel construction make them suitable for assemblies that require long-term reliability and resistance to moisture and oxidation.
Stainless steel material provides corrosion resistance and long-term durability in humid or outdoor environments
M3x40 mm thread diameter and length deliver a secure fit for standard M3 tapped components
Cylinder head design with flat bearing surface distributes clamping force evenly and prevents surface damage
10-piece set provides sufficient quantity for typical assembly or repair tasks without excess
What sets these screws apart
The combination of stainless steel and a cylinder head profile offers a balance of strength and surface protection that standard carbon steel screws cannot match. The metric M3 thread ensures compatibility with a wide range of standard tapped holes in electronics housings, model components, and mechanical assemblies.
Ideal for...
These screws are well suited for RC model construction, electronics enclosure assembly, and general workshop fastening tasks where corrosion resistance and a clean, flush finish are required. They are particularly appropriate for outdoor or humid environments where standard steel fasteners would degrade over time.
Application of OEM Cylinder Head Screws M3x40
Pre-drill or tap an M3 thread into the base material
Insert the screw and turn clockwise until the cylinder head sits flush against the surface
Verify the joint is secure and the screw is not over-tightened, which could strip the thread
Repeat for each remaining screw in the set as needed for the assembly
OEM is a generic manufacturer brand used for replacement and OEM-specification fasteners. The brand supplies metric screws and standard mechanical components primarily for hobby, workshop, and industrial applications. Products are typically sold in small set quantities and are valued for their material quality and dimensional accuracy.
These M3x40 mm cylinder head screws are used for fastening components in RC models, electronics enclosures, and general workshop assemblies where a flush finish and corrosion resistance are required.
They are made of stainless steel, which provides superior corrosion resistance compared to standard carbon steel. This makes them suitable for outdoor use and humid environments where ordinary steel fasteners would rust or degrade.
The screws have an M3 metric thread (3 mm diameter) and a total length of 40 mm. The head type is a cylinder head with a flat bearing surface for even pressure distribution.
The set contains 10 pieces, which is sufficient for most small-scale assembly or repair tasks. Additional sets can be purchased if a larger quantity is needed.
Yes, the internal hex socket (Allen key) drive requires a 3 mm hex key or Allen wrench for installation and removal.
