Discover more about the Metric Plain Hex Bolts range.

Plain Hex 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 Hex Bolts are designed for use alongside Accu’s Hex Nuts ranges.

As Hex Bolts are generally used with unthreaded holes, Plain Hex 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, Hex Bolts function similarly to a Dowel.

The minimum thread length of each Bolt is defined on each individual product page. Fully Threaded Hex 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, Polyamide and PEEK. Additional features such as Thread Locking Patches and Chemical Blackening are also available on Accu’s Stainless Steel Bolts.

Metric

Metric Plain Hex 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 Hex 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.
