M4.8 Slotted Pan Tapping

DIN 7971 Slotted Pan Head Tapping Screws Form C – A2 Stainless Steel

DIN 7971 Form C tapping screws are self-tapping fasteners designed to create mating threads in pre-drilled holes within sheet metal, plastics, and other suitable materials. The pan head design provides a broad bearing surface for effective clamping and load distribution, while the slotted drive allows installation using a standard flat-blade screwdriver. Form C screws feature a blunt point, making them well suited for use in pre-formed holes where thread forming rather than piercing action is required. These screws are sized by their thread diameter and overall length, measured from under the head to the tip.

Material

Manufactured from A2 stainless steel, these tapping screws offer excellent corrosion resistance along with dependable mechanical strength. A2 stainless steel performs well in humid and mildly corrosive environments, making it suitable for both indoor and outdoor applications. The natural stainless finish resists rust and staining while maintaining a clean, professional appearance and long-term durability without the need for additional coatings.

Use

DIN 7971 slotted pan head tapping screws Form C are commonly used in sheet metal assemblies, electrical enclosures, appliance manufacturing, ventilation systems, and general industrial equipment. Their thread-forming capability eliminates the need for separate tapping operations, helping simplify assembly and reduce installation time. The corrosion-resistant stainless construction and practical pan head design make these screws a reliable choice for maintenance, OEM manufacturing, and general fastening applications requiring dependable performance and easy installation.
