Σετ βιδών/μπουλονιών KS Tools 970.0800

The KS Tools 970.0800 screw/bolt set contains 750 pieces of M3 self-tapping screws manufactured to DIN 7981 standards. Total weight of the pack is approximately 630 g. These screws are designed for reliable fastening in thin sheet metal and plastic components where a countersunk head and cross recess are required. The set is supplied as a bulk pack intended to support repetitive assembly tasks in workshops, repair shops, and home DIY projects.

Advantages

These M3 screws conforming to DIN 7981 ensure consistent thread cutting performance and uniform head geometry for predictable countersinking. The cross (Phillips) recess simplifies quick alignment with powered or manual drivers. The standardized dimensions and material properties promote compatibility with a wide range of mating parts and commonly used pilot hole sizes. The bulk quantity reduces the need for frequent reordering and supports continuous work cycles.

Suitable for

• Fastening thin sheet metal to metal or plastic
• Electronics enclosures and small appliance assembly
• Repair and maintenance tasks in workshops and garages
• DIY projects requiring standardized countersunk screws

Key specifications

• Thread size: M3
• Quantity: 750 pieces
• Head type: countersunk (DIN 7981 style)
• Drive type: cross/Phillips
• Approximate pack weight: 630 g

How to use

Select a suitable pilot hole diameter according to material thickness and hardness, then position the screw perpendicular to the work surface. Use a matching Phillips screwdriver or a compatible powered driver with appropriate torque settings to avoid overdriving and thread stripping. For thin or brittle materials, start with a smaller pilot hole and increase as necessary to ensure secure engagement without deformation. When assembling multiple parts, verify alignment before final tightening.

Recommendations

Store the screws in a dry environment to prevent corrosion and keep the pack sealed between uses. For critical or load-bearing applications, verify material compatibility and consider using appropriate locking or sealing compounds. When using power tools, set torque limits to match M3 screw requirements to preserve thread integrity and head shape.
