Discover more about the Metric Plain Hexagon Bolts range

Plain Hexagon Bolts feature a standard hexagonal head, and are ideal for heavy-duty fastening applications. All components within this range are precision rolled to achieve general tolerances of +/-0.13mm. Plain Hexagon Bolts are designed for use alongside Accu’s Hexagon Nuts ranges.

As Hexagon Bolts are generally used with unthreaded holes, Plain Hexagon Bolts feature an unthreaded shank below the Bolt's head. The absence of a thread on this section of the Bolt results in a stronger, more uniform shaft, making the entire fastening more resistant to vibration and shear forces when the unthreaded portion is inserted into a correctly sized hole. In these applications, Hexagon Bolts function similarly to a Dowel.

The minimum thread length of each Bolt is defined on each individual product page. Fully Threaded Hexagon Bolts are also available.


Components within this range are available in a wide range of materials, including A2, A4 and A4-80 Stainless Steel, BUMAX, Brass, Phosphor Bronze, Polyamide and PEEK. Additional features such as Thread Locking Patches and Chemical Blackening are also available on Accu’s Stainless Steel Bolts.


Metric Plain Hexagon Bolts manufactured according to DIN 931, and are available in diameters ranging from M5 up to M20. Lengths of between 25.00mm and 600.00mm are also available as standard. Non-Standard sizes are available on request.


Imperial Plain Hexagon Bolts are available in thread diameters ranging from ¼ inch up to 1 inch, and lengths of between 1.1/4 inch and 20 inch. These components are manufactured to ANSI B18.2.1. Additional sizes are also available on request.
