DIN 963 machine screws are designed for applications where a flush surface finish and clean assembly are required. The slotted countersunk head allows the screw to sit level with the surface, making it suitable for panels, fabricated components, and precision assemblies where projection is not acceptable.
As a screw supplier in Mumbai, Vimal Industrial Corporation offers DIN 963 machine screw options in multiple sizes, materials, and finishes to match different industrial requirements. These machine screws are commonly used in electrical fittings, fabrication work, and general engineering applications where proper alignment and consistent threading are important.
Being one of the dependable machine screw suppliers, we maintain ready stock to support both bulk and ongoing requirements. Our range also supports applications where stainless steel fasteners are preferred for corrosion resistance and long-term performance. DIN 963 machine screws supplied by us are suitable for assemblies that require flush mounting, easy installation, and reliable fastening across different working conditions.
DIN 963 machine screws are preferred in assemblies where a flush fit and clean surface finish are required without any head projection. The slotted countersunk profile allows the screw to sit completely inside the material, making it suitable for applications where alignment and surface continuity matter.

The DIN 963 is designed to “disappear” into your material. It has a cone-shaped head (90-degree angle) that sits completely inside a pre-drilled hole. It is the perfect machine screw nut bolt for surfaces that need to stay perfectly smooth, like floor plates, hinges, or sliding tracks.
This is the most common mistake in the fasteners screws bolts industry! For most screws, you measure from under the head. But for DIN 963, the length is the “Overall Length” (from the flat top to the tip). Since the head stays inside the hole, it is counted in the total length. Always confirm this with your Fasteners Supplier India.
Yes, absolutely. DIN 963 screws use standard metric threads. You can pair them with a DIN 934 hex nut of the same size (like M4, M5, or M6). Many technicians in Mumbai use this setup when they want a clean, flush look on one side of a metal cabinet or panel.
Since the head is flat, you cannot easily use a spring washer on the screw side. The best way is to use a “Nylon-insert Lock Nut” (Nyloc) or a drop of thread-locking fluid on the back. Any expert Nut Bolt Supplier will help you choose the right locking solution for your heavy machinery.
Vimal Industrial Corporation provides fully certified DIN 963 stock with accurate head angles and high-quality thread tolerances. As a leading Nut Bolt Supplier, we offer same-day dispatch across India, ensuring your fasteners screws bolts arrive on time with full material test reports (MTR).
