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.
A Countersunk Nib is a bolt with a nib on one side to prevent the bolt from turning when fastening the nut.
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.
BOLT TYPE FASTENERS
Also known as a “coach” bolt, has a domed or countersunk head. The square section under the head grips into the part being fastened preventing the bolt from turning when the nut is tightened.
Hex Head Bolts
Hex tap bolts, hex cap screws, trim head hex cap screws, and hex serrated flange bolts fall under this category. They share a hexagonal head and are driven with a wrench. Can be used with or without washers in both timber and steel applications. These bolts are partially threaded.
