These Forgefix high-low thread Concrete Frame Screws are Zinc Yellow Passivated for increased resistance to corrosion. They offer a virtually stress free fixing, allowing close to edge applications. They are through-fixing, eliminating the need for marking and re-positioning when fixing batons etc. The Torx head of the screw enables increased torque control.
Supplied complete with cover caps and Torx bit.
Extremely popular fixing for window and door frames. Also now used as a versatile fixing for many applications in DIY, Joinery, Plumbing and Electrical trades.
The Zinc Yellow Passivation process of electroplating is similar to the 'Galvanised' and '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 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 heads were designed to prevent it and to achieve a desired torque consistently. TORX 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 and low thread heights.

Where products have been quoted as having free delivery or delivery included, this will not apply for Northern Ireland and the Highlands and Islands due to the excess delivery charges incurred reaching these locations. Delivery costs can be seen by entering your postcode into the basket.
Why do we charge delivery?
A great many of our customers purchase multiple products, so if we build the delivery charges into each item we will in effect be charging delivery on every product in their basket. We think it is fairer to charge a single delivery cost for the contents of the whole basket once. Some products do have delivery included; this is typically because they are dispatched from another location, generally direct from the manufacturer, as there are restrictions to how they can be delivered due to their size, or if they are liquids, for example.
