A deep recess, of a perfect shape, enables the same insert to be used for thousands of screwing operations. THREAD up to below the head, to allow the gripping of extremely thin sheets. PUNTA threaded right to the end, to allow the screw to gradually deform the material, creating a “drawing” effect, which increases the grip on thin she

CARBONITRIDING HEAT TREATMENT This confers two properties to the screw: - very hard surface, for biting into the fibres of the hardest wood; - tough, elastic core, needed to avoid breakage of screws. surface hardness carburizing depth PROTECTIVE TREATMENT To protect the screw from rust and corrosion, guaranteeing reliability over time. MUSTAD self-tapping screws are treated with products complying with the current RoHS laws. The 100 hours white zinc plating treatment guarantees a rust resistance a third higher than that of standard galvanizing. Complies with the EN1670 standard grade 3. core...
