Application guide for Self-Drilling Hollow Wall Anchors to Trade series (self-drilling hollow wall anchors). The core duty of the type 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. The typical industries, the how-to-specify checklist, assembly practice and the exclusion cases are set out below.
Typical Applications for Self-Drilling Hollow Wall Anchors
The most common settings where these are specified:
- Fit-out & drylining: fixing to plasterboard, block and hollow wall where there is no solid backing.
- General machine building: fastening covers, brackets, motors and sub-assemblies on production equipment.
- Maintenance & repair (MRO): a stocked size for servicing existing plant where the original fastener spec must be matched.
- 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.
How to Specify Self-Drilling Hollow Wall Anchors 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 (self-drilling hollow wall anchors). Quoting the standard on your order guarantees interchangeable dimensions between suppliers.
Where Self-Drilling Hollow Wall Anchors 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.
