Descripción del producto

¿Qué es este producto?

DIN 968 Stainless Steel Cross Recessed Pan Head Self Tapping Screws with Collar are screws designed for fastening thin metal sheets, plastic parts, panels, hardware components, and light-duty assemblies.

This product is a screw, not a bolt or nut. It has a unidad empotrada en cruz, cabeza redonda, y un integrado collar/washer-style flange under the head, which helps increase the bearing surface and improve fastening stability.

The sharp tapping thread allows the screw to form its own mating thread during installation, reducing the need for pre-tapped holes in suitable materials.
