AMF clamping screw set Nr. 6520 – 38-piece M12 set for 12 mm T-slots

The AMF clamping screw set Nr. 6520 is a machine-table workholding kit designed for secure clamping in 12 mm T-slots on fixtures and milling tables.

• For 12 mm T-slots
• M12 threaded components
• All parts quenched and tempered
• Supplied in wooden case with hinged lid

Secure clamping where it matters

The set is engineered for dependable workholding on machine tables and modular fixtures. With M12 threads matched to a 12 mm T-slot, the kit provides consistent preload and repeatable positioning for medium to heavy machining tasks. The combination of standardised thread size and slot compatibility reduces set-up time and minimises the need for bespoke fasteners, supporting faster changeovers and steadier machining cycles.

Built for high load and longevity

All components are quenched and tempered, offering improved fatigue resistance and dimensional stability during repeated tightening cycles. The inclusion of strength class 8 and 10 parts means the hardware can tolerate higher tensile and shear loads compared with lower-grade fasteners, which supports safer clamping under increased cutting forces. This durability reduces replacement frequency and helps maintain consistent clamping performance over time.

Organised kit for efficient workshop use

Presented as a 38-piece assortment in a wooden case with hinged lid, the kit keeps components organised and accessible at the bench or in the toolroom. Clear arrangement and sturdy storage accelerate selection of the required part and protect the hardware from surface damage when transported. The compact case supports tidy workshop practices and helps maintain productivity by keeping essential clamping elements to hand.

Compatibility, application and selection guidance

The clamping kit suits general-purpose fixtures, machine-bed set-ups and modular fixturing systems that accept a 12 mm T-slot and M12 hardware. For specific machine tables or unusual slot profiles, the thread and slot combination should be checked before installation. The set is ideal where robust, standardised clamping is required and where organised storage reduces setup time and operational interruptions.
