Discover more about the Imperial Plain Hexagon Bolts range.

Imperial Plain Hexagon Bolts are functionally identical to Accu's standard range of Hexagon Bolts. This type of bolt features unthreaded portion below the head, which serves as an unthreaded dowel to strengthen the overall construction of the bolt. The unthreaded section of a Plain Hexagon Bolt makes the bolt more resistant to shear forces.

Sizing

Plain Hexagon Bolts are available in imperial thread sizes of between 1/4 inch and 1 inch. Lengths range from 1 inch to 20 inch.

Thread-Locking and Finish Options.

Secure your Imperial Plain Hexagon Bolts against vibration-induced loosening with Accu’s pre-applied thread-locking solutions. From essential AccuLock Threadlocker to the rugged Anu-Lok 180 and high-performance Precote 80, we’ve got you covered. Elevate aesthetics with AccuBlack chemical blackening, reducing glare and adding a sleek, refined finish.
