Round Head Bolt
Round head bolts feature a button head and are largely used in wood connections. Round head bolts are same as the carriage bolts; however, they don’t have the square neck. As round head bolts are mostly used with wood, they do not exhibit high strength and are usually supplied in a standard ASTM A307 specification.
Countersunk Bolts
Countersunk bolts are often used to get a smooth surface. These bolts find their usage in projects such as railing, walkways, and bridge decking. Standard Thread Length Bolt lengths ≤ 6″: Thread length = (2 X diameter) + 1/4″ Bolt lengths > 6″: Thread length = (2 X diameter) + 1/2″ Inquiry Now
Machine bolts
Machine bolts, also known as cross arm bolts, are used primarily in the pole line domain. Machine bolts possess square heads & a semi-cone point. They generally have a square nut assembled. Moreover, they are usually hot dip galvanized so as to secure the steel. We supply machine bolts up to 1-1/2″ diameter. These bolts
Timber Spikes
Timber spikes are specially designed in a way wherein they pin together two or more wooden entities. These are provided with semi-cone pointed fetter drive threads that can be driven well into timber just like a nail, thereby speeding up installation. The head of the timber spike is huge and low profile, hence it provides
Carriage Bolts
Carriage bolts come with a round head and a square neck. These are largely used in wood connections. The neck’s square shape aids in placing the round head well into the wood hole, thus preventing bolt head from turning. Carriage bolts do not usually show high strength mainly because they are largely used with wood.
Square lag screws
Square lag screws come with a rustic look. They are used often in wood construction and sometimes for aesthetic purposes too. Square leg screws are generally available in the marketplace as a standard stock product. Standard Thread Length The minimum thread length for square lag screws shall be equal to half the nominal screw length
Hex lag screws
Hex lag screws are the best in the industry with six sided heads. A lot of bolts including ASTM A307 Grade A bolts and SAE hex bolts require a standard hex head. As far as specifications such as A307 grade B, A490 and A325 that require a heavy hex pattern is concerned, referring dimensional tolerances
Headed Anchor Bolts
These bolts are different from the anchor rods or the bent anchor bolts as their non-threaded end comes with a forged hex, square head, or heavy hex. To safeguard the structural steel columns, light poles, bridge rail, and substation structures, headed end of anchor bolts is usually embedded well into concrete foundations. And, available specifications
TIMBER BOLTS
Also known as dome head, fender head, safety head, mushroom head bolts and economy bolts in the Pacific NW; Timber bolts are used largely in marine and wood applications. The head of a timber bolt is rounded, bulky and low profile while there are two fins or nubs towards the base of its head. These
Square Head Bolts
It was the square head machine bolts that were the industry standard before Hex bolts became prominent. However, presently, square bolts are used largely for aesthetic purposes, offering a rustic finish to a new structure. Besides, they are also used to match existing fasteners of older structures. Square leg screws are also sometimes used to
