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.
U-Bolt
A U-Bolt has a U shaped shank that is threaded on both ends. This fastener is used for fastening to tubular objects such as poles.
