Mild Steel Bolts

Extensively used in most industries including construction, timber, engineering & mining.

​

Serrated Flanged Bolts

Serration prevents loosening of the bolts under strenuous conditions. Used in industries including timber and construction.

​

Countersunk Square Neck Bolts

Also known as Plough Bolts, these bolts are used wherever a countersunk finish is required - primarily in steel ant timber applications. 

​

Countersunk Nib

A Countersunk Nib is a bolt with a nib on one side to prevent the bolt from turning when fastening the nut.
