Verifying Performance Under Lateral Loads

London Fixing Testing Ltd provides independent on-site fixings shear testing to assess the performance of anchors and fixings when subjected to lateral (shear) forces. Fixings shear testing (also known as shear load testing) is a method of assessing how much lateral force a fixing or anchor can resist before failure or displacement. It is used where fixings bear horizontal loads, such as in cladding systems, scaffold tie designs, and steelwork connections.

What Is Fixings Shear Testing?

Fixings shear testing measures the load capacity of a fixing when force is applied parallel to the substrate surface. This type of testing is essential where fixings are required to resist sliding, horizontal movement, or combined loading conditions.

Shear testing is commonly specified when:

  • Fixings are subject to horizontal or lateral forces
  • Load paths differ from original design assumptions
  • Substrate conditions are uncertain or variable
  • Manufacturer data is unavailable

Our Shear Testing Services

We carry out shear testing on a wide range of fixings and substrates, including:

  • Mechanical anchors
  • Resin and chemical anchors
  • Bolts, studs, screws, and specialist fixings
  • Cast-in and post-installed anchors
  • Concrete, brickwork, blockwork, and stone

Testing is performed on-site using calibrated hydraulic testing equipment, ensuring accurate and repeatable results.

Fixings Shear Testing FAQs

What is fixings shear testing?

Fixings shear testing (also known as shear load testing) is a method of assessing how much lateral force a fixing or anchor can withstand before failure or excessive displacement. Force is applied parallel to the base material surface using calibrated hydraulic equipment, replicating the real-world loads a fixing may experience in service.

When is shear testing required?

Shear testing is specified when fixings are subject to horizontal or lateral forces that cannot be verified by manufacturer data alone. Common situations include façade and cladding systems, steelwork connections, scaffold ties, temporary works, and M&E installations. It is required when base material conditions are uncertain or when a structural engineer requests independent test data to inform design or better understand fixing performance in the available base material.

How does shear testing differ from pull-out testing?

Shear testing measures resistance to forces applied along the base material surface. Pull-out testing (also called tensile or pull testing) measures a fixing's resistance to forces applied perpendicular to the base material; essentially the force needed to pull the fixing out. Some fixings are subject to both tensile and shear forces simultaneously, which may require combined or separate assessments. A structural engineer can advise on the appropriate test type based on the installation design and fixing application.

What standards apply to fixings shear testing?

Fixings shear testing is typically carried out in accordance with BS8539, which is the ‘Code of practice for the selection and installation of post-installed anchors in concrete and masonry’. Testing may additionally be carried out to project-specific specifications or structural engineer requirements. All London Fixing Testing reports reference the applicable standards and are suitable for submission to building control, structural engineers, and other approving authorities.

How many shear tests are required?

BS8539 recommends performing shear tests on a minimum of 5 sample fixings of each type, in each available base material present on site.

How many shear tests can you complete in a visit?

With good access provided, we can complete 5 shear tests in a standard shift on-site.

How quickly can you come to site?

For urgent work we offer a same day test and certification service (subject to availability). Typically we can attend site within 2–3 working days. Call us to discuss your requirements.

How quickly can I have my test report?

We issue test reports within 24 hours of testing on-site. A detailed shear test report is provided, including incremental load displacement results & graphs, a description of failure mode if applicable, photographs, and engineer observations.

Do you conduct testing out of hours (weekend and night work)?

Yes, call one of our engineers, we can arrange this for you.

Do I need to book a site survey?

Typically this is not required, as we gather necessary information via a phone call or our one page form, that you can send to your advising engineer to complete and return, with drawings or photos from site.

What geographical areas do you cover?

We provide testing services in and around London, and travel across the UK for larger scale or more complex projects.
