The KS Tools 970.0420 set contains 550 screws/bolts manufactured to ISO 7049, with a total weight of 680 g. This collection groups multiple sizes and lengths commonly used in assembly, maintenance and repair tasks, providing a compact and standardized assortment for professional and hobby use. The screws are made to the ISO 7049 specification to ensure consistent thread form and dimensional compatibility with corresponding fasteners and components.

Advantages

Items in this set adhere to ISO 7049 dimensional standards, which promotes interchangeability and predictable fit in threaded connections. The wide quantity — 550 pieces — reduces the need for frequent reordering and supports jobs that require many identical fasteners. The overall weight and packaging make the set easy to store and transport, and the standardized threads simplify selection and inventory management.

• General mechanical assembly and maintenance
• Workshop repair tasks and small-scale production runs
• Equipment and appliance servicing
• D.I.Y. projects requiring standardized screw sizes

Key specifications

• Quantity: 550 pieces
• Standards compliance: ISO 7049 thread/dimensional specification
• Total set weight: 680 g
• Material: steel (standard industrial grade)

How to use

Select screws from the set that match the required diameter, thread pitch and length for the application. Verify compatibility with mating threads or nuts before installation. Use appropriate hand tools or power drivers with correct bit sizes to avoid damaging heads or threads. Tighten fasteners to the specified torque values for the assembly; if torque specifications are not available, apply moderate, even force and inspect the connection for secure engagement.

Recommendations

Store the screw set in a dry environment to prevent corrosion and keep pieces sorted by size where possible to speed up selection. For critical assemblies, clean mating threads and apply thread locker or lubrication only when specified. Replace any fastener that shows signs of damage or excessive wear rather than reusing it in safety-related applications.
