![]() The shaft has no threads, and its diameter corresponds to the side of the square cross-section. The head of a carriage bolt is usually a flat dome. This allows the fastener to be mounted from one side with just one tool, a wrench or wrench. This makes the bolt self-locking when inserted through a square hole in a metal band. It differs from other bolts by its flat mushroom head and the fact that the cross-section of the shank, although circular for most of its length (as with other types of studs), is square just below the head. Also known as a washer head screw in Australia and New Zealand. Carriage boltĪ carriage bolt is a form of Bolt that is used to fasten metal to metal, or more commonly wood to metal. The effectiveness of the blind bolt solution means that, for decades, they’ve been the first choice for restricted access work in sectors like manufacturing, construction, and repair work. On many occasions, restricted access means that using rivets or hex bolts is out of the question, and blind bolts were developed to deal with that exact problem. They were designed to forge a strong connection where traditional rivets or hex bolts were difficult to assemble or just couldn’t do the job. Blind boltsĪ blind bolt is a structural fastener that provides more strength and conformability than a typical rivet or weld. This reverse thread is essential and is part of the main function of the arbor bolt. When you look at the shaft of an arbor bolt, it looks like it is backward as it has an inverted tread pattern like other types of bolts. Typically, arbor bolts are made with a dark or black finish. ![]() These bolts also have a head with a sunken design that creates a noticeable ridge around the head of the bolt. The enclosed washer gives the Arbor bolts a very distinctive appearance right from the start. All arbor bolts have a washer that is permanently attached to the tip of the bolts. On all American stationary saws that use a 10 “blade, the arbor is 5/8” in diameter where the blade is attached.Īrbor bolts differ from other bolts in that they are delivered pre-assembled. The arbor is the shaft that holds the blade. These bolts hold the tool securely and keep the blade in place. Arbor BoltsĪrbor bolts are specifically designed for use with power tools, typically miter saws. A common case of a non-load-bearing element attached to a structure is the connection between a facade system and a reinforced concrete wall. Anchor bolts transmit different types of loads: tensile forces and shear forces.Ī connection between structural elements can be represented by steel columns that are attached to a reinforced concrete foundation. The connection can be made using a variety of different components: anchor bolts, steel plates, or stiffeners. Anchor bolts are used to connect structural and non-structural elements to concrete.
