This is a metric machine screw designed specifically as a replacement and maintenance fastener for tile cutting machines and similar workshop equipment. Its primary use is to secure components such as guide rails, blade housings, mounting plates and guards on wet or dry tile cutters where a reliable, machine-grade fastening is required and regular exposure to water and cutting slurry is likely.

The screw is manufactured in A4 stainless steel (corrosion resistant 316 grade) with a passivated bright finish and a nominal strength rating equivalent to A4-70. Threading is standard ISO Metric coarse thread (to ISO 261 / ISO 965), ensuring full compatibility with metric tapped holes and nuts. The head style supplied is a hexagon socket head cap (to ISO 4762), driven with an Allen key for positive torque transmission in confined spaces. The combination of A4 material and hex-socket head makes the fastener suitable for repeated removal and reassembly without damage to the drive or head.

Typical applications include routine maintenance and assembly of tile cutting machines used in construction, tiling and stone fabrication workshops, plant hire fleets and general toolrooms. It is also suitable for fixing ancillary items on damp or abrasive machinery where cutters use water to suppress dust, since the A4 stainless composition resists pitting and crevice corrosion from chlorides and cutting fluids better than A2 grades.

Key benefits of this tile cutting machine screw are its corrosion resistance in wet working environments, reliable mechanical strength for machine assembly, and compatibility with standard metric tools and replacement parts. The hex socket drive reduces the risk of cam-out compared with slotted or Phillips drives, and the A4 material minimises staining and seizing when in contact with water and abrasive slurries. For applications needing extra security, the screw accepts common locking options such as nylon-insert nuts, spring washers or threadlocking adhesives.

Duchy Fasteners stocks this tile cutting machine screw in a range of metric sizes and lengths (commonly M4 to M10, lengths 6 mm–80 mm) and in practical pack quantities (single pcs and multi-packs such as 10, 25 and 100). It is offered as a direct replacement for Draper part DR38861 and is suitable for most tile cutter makes where an ISO metric hex-socket machine screw is specified.
