Vimal Industrial Corporation is a leading supplier and stockist of DIN 7972 self-tapping screws based in Mumbai, India. Manufactured in accordance with DIN 7972 standards, these screws feature a slotted countersunk combined with a thread-forming design that enables direct installation into thin sheet metals, plastics, and light alloys without pre-tapping. The countersunk design provides a broad bearing surface, making them suitable for secure fastening where head pull-through resistance is critical.
We maintain a comprehensive inventory of DIN 7972 screws across sizes, materials, and protective finishes to serve OEMs, electrical panel builders, fabricators, EPC contractors, and MRO teams requiring high-quality fastening solutions with reliable supply and technical documentation.
As India’s electrical, appliance, and fabrication sectors continue to rely on slotted fasteners, demand for DIN 7972 self-tapping screws remains strong. Vimal Industrial Corporation partners with leading manufacturers like APL Fasteners to provide a consistent supply of screws conforming to DIN dimensional tolerances.
All screws are stocked in climate-controlled warehouses, inspected for dimensional accuracy, and available with mill certificates, lot traceability, and third-party inspection reports. With a strategically located Mumbai facility and nationwide logistics network, we ensure same-day dispatch for urgent requirements and scheduled supply contracts.

DIN 7972 screws are slotted countersunk self-tapping fasteners designed to cut their own threads in sheet metal, plastics, and light alloys. Their countersunk provides a large bearing surface, ensuring strong clamping and reduced risk of pull-through in thin materials.
According to the standard, DIN 7972 screws are produced in thread diameters from 2.2 mm to 9.5 mm with lengths ranging from 4.5 mm to 50 mm. The standard also specifies tolerances for head geometry, slot width, and thread profile to guarantee interchangeability across applications.
They are commonly made from case-hardened carbon steel for general use and stainless steel grades (A2 and A4) for corrosion resistance. Popular surface finishes include zinc plating, nickel coating, black oxide, and plain/oiled, allowing selection based on environmental and performance requirements.
DIN 7972 screws are widely used in electrical panels, consumer appliances, HVAC systems, automotive interiors, and sheet-metal fabrication. Their slotted drive makes them compatible with standard hand tools, making them suitable for both mass production and MRO (maintenance, repair, and overhaul).
As an authorized APL Fasteners dealer in Mumbai, Vimal Industrial Corporation offers a complete range of DIN 7972 screws with ready stock, same-day dispatch, mill certificates, lot traceability, and third-party inspections. Our pan-India logistics and customer-focused service ensure reliable supply for OEMs, contractors, and industrial buyers.
