The primary duty of Concrete Formwork Snap-Tie Wedges is fixing steelwork, plant and services to concrete and masonry, where the anchor is set in a drilled hole and its capacity is governed by the base material rather than by the steel. Below: the sectors that specify them in volume, the checklist used to select the right size and material for the application, installation notes, and the known limits of the type.
Typical Applications for Concrete Formwork Snap-Tie Wedges
The most common settings where these are specified:
- Fabrication & metalwork: bench and on-site assembly of steel frames, enclosures and weldments.
- Structural fixing to concrete: base plates, brackets, rails and steelwork bolted to a concrete slab or wall.
- Building services: suspending cable tray, ductwork, sprinkler pipe and unistrut from a soffit.
- Plant & machine installation: holding down machines, presses and conveyors on a factory floor.
- Fit-out & drylining: fixing to plasterboard, block and hollow wall where there is no solid backing.
How to Specify Concrete Formwork Snap-Tie Wedges for Your Application
- Size: Match the size to the mating part — see the dimension table below for each option.
- Material: Choose the material and finish for the service environment — plated steel for general use, stainless for corrosion resistance.
- Environment: For damp, coastal or chemical exposure prefer A4/316 stainless or a suitable coating; indoors, plated steel or A2 is usually sufficient.
- Standard: This product is supplied to Trade series (snap-tie wedges). Quoting the standard on your order guarantees interchangeable dimensions between suppliers.
Where Concrete Formwork Snap-Tie Wedges Are Not the Right Choice
Match the fastener to the load, environment and whether the joint must be reopened; the wrong class or style is the usual cause of joint failure.
