Yes, in fact, it’s preferred. Since a flat point doesn’t need to penetrate the surface to work, it is excellent for locking against hardened steel shafts where a pointed screw would simply blunt itself. A reliable Fasteners Supplier India will tell you that the flat point relies on pure friction to keep the screw nut bolt assembly stable.
Because the DIN 913 is headless, it sits entirely within the threaded hole. This “Flush Mounting” is critical for rotating parts. It ensures there is no protruding bolt fastener head to catch on worker clothing or interfere with other moving parts. It’s the cleanest looking Industrial Hardware for modern machinery.
Absolutely. Because the flat point doesn’t “self-centre” like a cone point, you have more control over the exact axial position of the part. This makes these fasteners screw bolts a favourite for optical equipment and measuring tools where microscopic accuracy of the bolt fastener is required.
It’s all about the tip. DIN 913 is a Flat Point (non-destructive), while DIN 914 is a Cone Point (penetrating). If you want to keep your shaft looking brand new, choose 913. If you want a permanent, “dig-in” lock, ask your Nut Bolt Supplier for the 914 version.
For industrial-grade, certified hardware, Vimal Industrial is the leading Nut Bolt Supplier Mumbai. We maintain a massive inventory of DIN 913 in both high-tensile and stainless steel, providing full Material Test Reports (MTR) to ensure your screw nut bolt project meets international safety standards.
