Channel Nuts & Structural Fasteners
Engineered connection hardware designed for maximum pull-out strength, slip resistance, and rapid modular installation across standard 41×41mm and 41×21mm strut channel assemblies.
Intaglio-toothed contact profiles bite directly into strut channel return lips for permanent non-slip retention under high dynamic loads.
Available in High-Tensile Carbon Steel (Grade 4.8 / 8.8 / 10.9) and Corrosion-Resistant 304/316 Stainless Steel or Proprietary Aluminum Formulations.
High-elasticity zinc-plated spring wire retains the nut securely in position during vertical and overhead cantilever bracket alignments.
Sub-Categories & Dedicated Hardware
Select from our specialized line of strut-compatible channel nuts, washers, threaded components, and non-drill anchoring solutions designed for industrial MEP support assemblies.
Spring Washers
Helical split lock washers that generate continuous spring reaction tension, preventing bolt loosening caused by equipment vibration, thermal cycling, or dynamic loads.

- Standards: DIN 127B, ASME B18.21.1
- Finishes: Zinc Plated, HDG, SS 304/316
Flat Washers
Precision-stamped plain and heavy-duty load distribution washers providing smooth bearing surfaces and preventing indentation or surface damage to strut channel profiles.
- Types: Standard Form A, Large OD (DIN 9021)
- Thickness: 1.5mm to 4.0mm heavy gauge
- Materials: Carbon Steel Q235, SS 316
Hexagon Nuts
High-strength full hexagon nuts, nylon locking nuts (DIN 985), and flange nuts matched with threaded rods and channel bolts for reliable mechanical clamp connections.

Non-Drill Anchors
Pre-installed cast-in insert anchoring solutions and friction mechanical anchors that eliminate concrete drilling, protecting reinforcement rebar and preventing structural damage.
- Design: Pre-cast embedment channel integration
- Advantage: Zero dust, noise, or rebar cutting
- Fatigue: Tested up to 2 Million cycles
Threaded Rod Connectors
Elongated round and hexagonal coupling sleeves (DIN 6334) engineered to extend threaded drop rods, transition between varying thread diameters, and connect overhead pipe hangers.
- Length: 3×D standard engagement length
- Types: Hexagon sleeve, Round sleeve, Step-down
- Load Rating: Matches parent rod yield limit
Threaded Rods
Continuous fully-threaded studs and hanger rods in 1m, 2m, and 3m lengths manufactured to strict pitch tolerances for ceiling trapeze supports and mechanical cable tray suspensions.
- Length: 1000mm, 2000mm, 3000mm, cut-to-size
- Steel Grade: 4.8, 8.8, B7, SS304/316
- Tensile: Up to 800 MPa nominal strength
Strut Channel Spring Nut Variants
Lonsonstrut channel nuts are manufactured with specialized grooves that interlock with the in-turned lips of the strut profile. When tightened, the teeth bite into the steel, generating an unyielding positive mechanical lock.
For 41×41mm, 41×62mm, and 41×82mm deep channel channels.
Optimized for 41×21mm shallow channel profiles and space-constrained runs.
Traditional channel nut for floor-mount frames and horizontal sliding adjustments.
Plastic or steel top-retained spring for rapid blind overhead insertion.

| M8 / 5/16" | 6.0 mm | 9.5 kN | 5.0 kN | 28 Nm |
| M10 / 3/8" | 8.0 mm | 15.0 kN | 8.5 kN | 55 Nm |
| M12 / 1/2" | 9.5 mm | 19.5 kN | 12.0 kN | 80 Nm |
| M16 / 5/8" | 11.5 mm | 22.0 kN | 14.5 kN | 120 Nm |
Built for Structural Integrity in Demanding MEP Projects
Our fasteners undergo rigorous manufacturing controls from cold forging and precision tapping to electroplating and salt spray testing.
High Slip Resistance
Integrated intaglio teeth deliver an approximate 83% improvement in resistance against axial slippage when torqued properly.
Anti-Vibration Lock
Spring washer and nylon nut configurations prevent loosening under continuous vibrations from HVAC pumps, rail lines, and fans.
Severe Corrosion Protection
Hot-dip galvanized (HDG) coatings over 45μm and stainless alloys guarantee long service life in utility tunnels and coastal substations.
Zero Concrete Damage
Non-drill insert anchoring channels embed flush into pre-cast concrete structures, protecting critical rebar arrays.
