01DRILL & SCREWDRIVER ACCESSORIES
Precision fasteners in an organized case
A comprehensive collection of black carbon steel fasteners, this kit sits ready on the workbench or tucked into a workshop drawer. It brings order to the small but critical components that hold machinery, furniture and electronics together.
Designed for repair and assembly, it suits makers, technicians and home users who need precise installation across multiple projects without hunting for individual screws.
02MATERIALS
Carbon steel built for durability
The screws are forged from high-quality carbon steel, chosen for its balance of workability and strength. This material delivers high hardness and toughness, ensuring the fasteners maintain their integrity through repeated use. The black finish adds a layer of resistance against corrosion and oxidation, making the set suitable for environments ranging from cold workshops to humid garages.
TOOLS
Included hex keys for access
To drive these socket head cap bolts, the kit provides specific hex Allen keys. The set includes a 1.5mm key for M2 screws, a 2.5mm key for M3, and a 3.0mm key for M4, with dimensions tailored to fit the screw heads precisely. Having the correct tool alongside the fastener ensures efficient installation and reduces the risk of stripping the hexagonal recess during assembly.
STORAGE
An organized case for clarity
All 1225 pieces are housed in a dedicated storage box that arranges components neatly. This organization prevents the common frustration of losing small washers or mixing up screw lengths. Quick identification is possible at a glance, which is essential when working on complex repairs where the wrong size can cause significant delays. The case supports convenient storage and reduced loss over time.
