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.

Materials

Components within this range are available in a wide range of materials, including A2, A4 and A4-80 Stainless Steel, BUMAX, Brass, Phosphor Bronze, Nylon (Polyamide), and PEEK.

Ensure your Metric Plain Hexagon Bolts stay secure with our advanced pre-applied thread-locking patches. Whether you need AccuLock Threadlocker for essential fastening, Anu-Lok 180 for added grip, or Precote 80 for maximum performance, we have the right solution. For a refined aesthetic, AccuBlack chemical blackening reduces glare while enhancing the surface finish.

Metric

Metric Plain Hexagon Bolts manufactured according to DIN 931, and are available in diameters ranging from M5 up to M52. Lengths of between 20mm and 600mm are also available as standard. Non-Standard sizes are available on request.

Imperial

Imperial Plain Hexagon Bolts are available in thread diameters ranging from ¼ inch up to No.12, and lengths of between 1/4 inch and 12 inch. These components are manufactured to ANSI B18.2.1. Additional sizes are also available on request.
