700-Piece Metric and SAE Set Screw Kit

This assortment contains 700 headless socket set screws across 25 metric and SAE sizes, manufactured from 12.9 grade alloy steel with black oxide finish. Metric sizes follow DIN 916 and SAE sizes follow ASME B 18.3 standards. The cup-point design bites into mounting surfaces to secure shafts, pulleys and collars without protruding heads. Eight matching hex keys are included for installation.

Check Thread Size and Drive Compatibility

Verify that your application requires the exact thread pitches and diameters listed, such as M3 through M8 metric or 1/8-inch through 5/16-inch SAE variants. Ensure the internal hex drive matches the supplied keys and that the headless grub-screw profile suits the recessed mounting holes in your equipment. Confirm that 12.9 grade alloy steel meets the mechanical strength and corrosion resistance demanded by the operating environment.

Eight Hex Keys Enable Immediate Use

The bundled hex keys correspond to the internal drives across the 25 sizes, so no separate tool purchase is needed for assembly or maintenance tasks. Having the correct keys on hand reduces downtime when adjusting faucets, door handles, 3D printers, CNC machines or other fixtures. The organised storage case keeps screws and keys sorted by size for quick identification during repairs or production runs.

Questions about this item

Does the 700-piece SVC05001 kit include the hex keys needed to drive the socket set screws, or must they be purchased separately?

The assortment comes with 8 hex keys matched to the internal hex drives of the included metric and SAE set screws, so no separate driver purchase is required.

How do I decide between the 25 metric and SAE sizes in this 12.9 alloy steel assortment for a specific repair?

Choose the thread diameter and length that match the tapped hole: metric options range from M3 to M8 in lengths up to 10 mm, while SAE options cover 1/8"-40 through 5/16"-18 in lengths up to 5/16 inch.

What does the 12.9 grade rating mean for the holding power of these cup-point set screws once installed in a machine?

The 12.9 alloy steel provides high tensile strength and hardness, allowing the concave cup point to bite securely into shafts or collars without stripping under heavy torque loads.
