Supplied complete with cover caps & Torx® compatible bit. APPLICATION: Extremely popular fixing for window & door frames. Also now used as a versatile fixing for many applications in DIY, Joinery, Plumbing & Electrical trades. The Zinc Yellow Passivation process of electroplating is similar to the ' Galvanised' & ' Zinc Plated' processes but with the addition of a yellow dye. It offers an aesthetically pleasing finish, whilst having excellent resistance to corrosion. By design, TORX® compatible head screws resist cam-out much better than Phillips or Slotted screws. Where Phillips heads were designed to cause the driver to cam out, to prevent over-tightening, TORX® compatible heads were designed to prevent it & to achieve a desired torque consistently. TORX® compatible head sizes are described using the capital letter 'T', followed by a number. A smaller number corresponds to a smaller point-to-point dimension of the screw head. Only the proper driver can drive a specific head size without risk of ruining the driver or screw. High-Low Thread screws have an excellent holding power in wood due to their alternating high & low thread heights.
