Frequently asked questions
What fixing accessories does CMT Group supply for construction and civils projects?
CMT Group supplies nuts, washers, studding, channel components, drill bits, injection resin accessories, silicone, end caps and accessory sets for trade orders, project supply and repeat procurement. The range covers bolted assemblies, threaded rod work, channel support systems, resin fixing, drilling preparation, nylon fixing, sealing and finishing.
You can narrow the range by accessory type, thread size, diameter, length, finish, pack quantity and system compatibility. Check product data to confirm the specific fixing accessory meets your base material, loading and installation requirements before ordering.
What should you check before ordering studding or channel components for a channel support system?
Before ordering studding, confirm thread size, length, grade and finish against the channel and fixing components in your system. For channel nuts, check compatibility with the channel section and verify product data supports the load and installation requirements.
For wedge nuts used alongside studding in formwork or shuttering systems, confirm thread size and wedge nut type against the formwork or shuttering system before ordering. Where a system is specified by a structural engineer, use only the compatible components listed in the manufacturer's product data.
What is the difference between full nuts, channel nuts and wedge nuts?
Full nuts are standard threaded fasteners used to secure bolts, threaded rod or studding in a wide range of general fixing applications. Confirm thread size, grade and finish before ordering.
Channel nuts are designed to locate within a channel section and allow adjustment along the channel before tightening. They are used in channel support systems for fixing to structural steel, concrete and other substrates. Wedge nuts are used for formwork and shuttering systems, including tie rod and she-bolt applications where product data supports compatibility. Check thread size, wedge nut type and the formwork system before ordering.
What should you check before ordering nylon fixings or drill bits?
For nylon fixings, confirm diameter and length against the screw or fixing size before ordering. Check product data confirms the nylon fixing is suitable for the substrate (masonry, blockwork or concrete) and fixing duty. Frame fixings and wall plugs are available in a range of diameters and lengths.
For drill bits, confirm diameter and length match the hole size required for the fixing system. Check shank type (standard, SDS-Plus or SDS-Max) is compatible with your drill. Confirm the drill bit is rated for the substrate and drilling method in the product data before ordering.
Can injection resin accessories and mesh sleeves be ordered alongside anchor resins?
Yes. Injection resin accessories, including mesh sleeves and mixing nozzles, are available in the fixing accessories range and can be ordered alongside chemical anchor resins and applicator guns from CMT Group. Mesh sleeves may be required when injecting resin into hollow substrates such as hollow block or perforated brick, depending on the resin system, substrate and product data.
Confirm mesh sleeve diameter matches the drilled hole and threaded rod size before ordering. Check nozzle and mixing tip compatibility with the resin cartridge and applicator gun. You can order resin accessories alongside the wider chemical anchor resin and applicator range from the Fixings, Fasteners and Resins category.
What should you check when ordering silicone or sealant products?
Before ordering, confirm the silicone type (neutral cure, acetoxy or equivalent) is suitable for the substrate and application. Neutral cure silicone is generally suitable for a wider range of substrates, including some metals and coated surfaces, where acetoxy types may not be appropriate.
Check cartridge size, colour, intended application and product data before ordering. Where a specific fire rating, watertight performance or other technical requirement applies, confirm product data supports that requirement. Check the technical data sheet before use to confirm suitability for your substrate and application conditions.
Can CMT Group support repeat orders, project quantities and trade accounts for fixing accessories?
Yes. CMT Group supplies fixing accessories to trade accounts, framework accounts, project procurement teams and depot replenishment requirements. The EDGE B2B Portal allows account holders to manage repeat orders, check stock, track deliveries and access trade pricing directly.
For volume requirements, project supply planning or depot replenishment, speak to the team or use your EDGE account. The wider supply service is supported by supplier-level accreditations including CHAS Elite, BSI ISO 9001:2015 Quality Management and ConstructionOnline Gold. These accreditations support procurement confidence around safety management, quality processes and supplier assurance. Product suitability still depends on the individual accessory type, thread specification, system compatibility, installation requirements, manufacturer guidance and any project-specific requirements.
