The SPAX-typical T-STAR plus drive is a so-called hexalobular socket. This shape increases the contact surface of our T-STAR plus and the T-STAR plus bits sit perfectly in the screw head. The best possible power transmission from screwdriver to screw thanks to T-STAR plus enables you to work quickly and much more efficiently than with all other drives. Where the countersunk head screw has a flat design for flush countersinking of the screws, the raised countersunk head has a convex rounding. Depending on the screw type and surface finish (stainless steel, nickel-plated, antique), these screws become a decorative element in furniture construction or when fixing skirting boards, for example. The partially threaded screws are ideal for fastening thin components such as wood-based panels, boards or planks to thicker components such as squared timber or beams. The short thread screws into the thick component, while the unthreaded shank remains in the attachment. This creates the maximum contact pressure between the two. The non-threaded part should be at least as thick as the attachment. The CUT point of our SPAX screws enables our wood screws to be screwed in extremely quickly and effectively without pre-drilling. In combination with the wave profile, the arrow-shaped CUT point reduces splitting and tearing of the wood. In addition, the CUT tip enables the screw tip to be positioned very precisely and without slipping, even on smooth surfaces. The abbreviation A2 for our stainless steel screws comes from the alloy of the steel. A2 stainless steel screws offer high protection against corrosion and medium strength. Their resistance to seawater and acids is low. They are therefore used outdoors in areas far from the coast.
