DIN 7985 machine screws are widely used in assemblies that require a strong head profile, consistent threading, and controlled tightening. Designed with a cross-recessed (Phillips) pan head and metric thread, these screws provide better grip during installation and ensure stable fastening across metal, plastic, and composite components. The pan head design offers a wider contact surface, supporting uniform clamping and reducing the risk of surface damage.

The DIN 7985 has a wide, rounded head that sits on top of the surface. Unlike countersunk screws that can crack thin plastic or soft metal, the pan head acts like a built-in washer. It spreads the clamping force of the bolt fastener over a larger area, making it the safest machine screw nut bolt for electrical housings and delicate panels.
Mumbai has a high salt content in the air. In a standard steel screw, the deep Phillips cross-recess is the first place where water sits and starts rusting. A professional Nut Bolt Supplier will always suggest Stainless Steel Fasteners (A2 or A4) to prevent the head from rusting and “stripping” when you try to repair the machine later.
Yes, for almost all practical purposes. ISO 7045 is the international version of the German DIN 7985. They have the same head shape and Phillips drive. As a leading Nut Bolt Supplier Mumbai, we keep both in stock so your project stays compliant with both local and global engineering specs.
Absolutely. DIN 7985 screws have standard metric threads (M2, M3, M4, etc.). They pair perfectly with any DIN 934 hex nut. Many electronics manufacturers in India use this machine screw nut bolt combination with a small washer to ensure a vibration-proof grip.
We provide “Traceable Quality.” Every DIN 7985 screw we supply comes with a Material Test Report (MTR). Whether you need M2 for a circuit board or M10 for a heavy machine, we are the Nut Bolt Supplier Mumbai that guarantees high-strength, precision-forged fasteners screws bolts with pan-India delivery.
