Threaded rods are designed to provide superior strength and durability for fastening applications in HVAC systems, machinery and sheet metal operations. These rods have a similar appearance to that of a screw. Their threading extends around and along the unit to generate rotational movements. They combine linear and rotational movement to resist strong pressure. Raptor Supplies offers a wide range of these threaded rods from brands like Grainger, A.R. North America, Cooper B-Line, Calbrite, Super-Strut and Fabory. These rods feature male threads running through their entire length and are available in stainless steel, carbon steel, alloy steel, nylon and aluminium variants.
Features
Threaded rods are screwed into place to mount, brace, hang, support and reinforce components in assemblies and structures.
They are ideal for use in construction, metal fabrication and machine repair tasks that require extended reach or lengths.
They can be cut to the desired length with a saw, grinder or a similar tool.
Cooper B-Line Threaded Rods:
Provide good gripping power to make installation easy.
Made of fire-retardant (FR) resins, polyester and vinyl ester ideal for corrosive environments.
Buying Guide
Based On Material
Brass
Corrosion resistant in wet environments, electrically conductive and non magnetic
Carbon Fibre
Does not warp at extreme temperatures (ideal for heat treatment procedures & furnace fixtures) and excellent strength-to-weight ratio
Nickel
Commonly used in valves, pumps and shafts. Resist salt water and caustic chemicals. 400 nickel also known as Monel
Steel
Ideal for light-duty hanging, mounting & fastening
Aluminium
Lightweight, resist corrosion in wet environments and non magnetic
Bronze
Stronger and more resistant to salt water than brass rods
Fibreglass
Stronger than nylon threaded rods and resist acids, solvents, salt water & oil
Plastic
Resist oil, grease & solvents (except mineral acids); and nonconductive (good for use around sensitive electrical components)
Stainless Steel
Excellent resistance to chemicals & salt water. Wear resistant. Meet temperature & pressure requirements of ASTM A193
Titanium
High strength-to-weight ratio and nonmagnetic
Based On Finish / Coating
Black Oxide
Dark surface colour and corrosion-resistant in dry environment
Blue PTFE Coating
Chemical resistant and slippery surface to thread on smoothly
Zinc Plating
Stops moisture from penetrating into the base metal, preventing rust
Hot-Dipped Galvanised
Thick coating for better corrosion resistance than zinc plating; must be used with other hot-dipped galvanised fasteners
Zinc Yellow-Chromate Plating
Resist corrosion in wet environments
Based On Thread Type
Fully Threaded
Threads run on the entire length for full engagement of nuts or other female-threaded components. High grip strength & evenly distributed tension when mounting & securing components
Threaded on Both Ends
Threaded at each end with an unthreaded portion at the centre. Often bent for making specialised fasteners such as anchor bolts and U-bolts
Threaded on One End
Unthreaded end can be used as a pivot point, hinge, shaft or locator pin

Based on Thread Spacing
Coarse Thread Spacing
Spaced widely for an easy start with the fewest turns to tighten. Deep & thick configurations minimise the chance of stripping or jamming, even if nicked, dirty or rusty
Fine Thread Spacing
Spaced closer to prevent loosening during vibrations. Ideal for making precise adjustments as fine threads travel a short distance with each turn
Extra Fine Thread Spacing
More closely spaced than fine threads. Travel a very short distance for facilitating precise, incremental adjustments
Ultra Fine Thread Spacing
Extremely close spaced for making precise & incremental adjustments on measuring devices, optical fixtures and lab equipment
Based on Thread Direction
Right Hand
Thread flanks rise from bottom left to top right allowing the user to apply a greater torque when turning the lead screw clockwise than against it
Left Hand
Thread rises from bottom right to top left when viewed from the front. Can be tightened by turning to the left; once fastened they resist loosening from counterclockwise motion
