Discover more about the Metric Full Thread Hexagon Bolts range
Fully Threaded Hexagon Bolts are designed for use in heavy-duty fastening applications, and feature a hexagonal head for use with a standard spanner. As their name suggests, these fasteners are threaded all the way up to the head of the bolt, making them ideal for installation into pre-threaded holes. Plain Hexagon Bolts, with a reinforced unthreaded shaft section, are also available.
All Full Thread Hexagon Headed Bolts are precision rolled to achieve general tolerances of +/-0.13mm. These components feature a full thread which runs the entire length of the bolt's shaft, and are designed for use alongside Accu's Hexagon Nuts ranges.
Vented Hex Bolt Variant
Accu can also offer this component with a hollow shaft, which allows gases and contaminants to pass through the core of the screw. Vented Hexagon Bolts are commonly used within vacuums.
Fully Threaded Hexagon Bolt Materials
Components within the Full Thread Hexagon Bolts range are available in an array of materials, including A2, A4 and A4-80 Stainless Steel, BUMAX, Brass, Phosphor Bronze, Nylon, Polypropylene, Polyvinylidene and PEEK. Additional features and finishes such as Thread Locking Patches and Chemical Blackening are also available on Accu’s Stainless Steel bolts.
