Turnbuckle

Archives

A turnbuckle is also called a bottle screw or a stretching crew because it has the “stretching” effect on ropes, cables, and other tensioning systems when the tension or length is adjusted.  A turnbuckle can consist of two threaded bolts: an eye bolt and a hook bolt screwed into each end of a small metal frame. Sometimes, it can be two eye bolts.

A turnbuckle has many uses, usually one that needs a lot of tension. Because of this, a turnbuckle can vary in size and weight–from the ten-gram turnbuckle for a home application to a thousand-kilogram one for bridges and buildings. Turnbuckles are secured with either a wire clip or a lockwire 

In aircraft, a turnbuckle is used to adjust the tension on structural wires for the wings and on flexible cables for the flight control systems. In shipping, a turnbuckle is used for rigging and lashing. In sports, a turnbuckle is used for boxing rings or wrestling rings to adjust the tension of the ropes.

Stainless Steel Screws and Sockets

304 Stainless Steel Hexagonal Capscrew

Hexagonal Cap Screws, or hex cap screws, are one of the most common fasteners used on the several industries today. By the name itself, hexagonal cap screws are fasteners featuring a hexagonal head with a washer face on the bearing surface and a chamfered point. They are commonly used in applications such as construction and machine assemblies.

Oftentimes, hex cap screws are mistaken for hex bolts. However, these two fasteners are totally different in many ways including the manner of use or installation. Hex bolts are installed by turning a nut to tighten the fastener while hex cap screws are installed into tapped holes by turning the head to assemble and tighten. Physically, hex cap screws feature a washer face on the bearing surface and the chamfered point, a characteristic hex bolt don’t have.

18-8 Stainless steel fasteners such as the 304 Stainless Steel Hexagonal Cap Screw are the most popular type of stainless used in the production of fasteners. Its composition is approximately 18% chromium and 8% nickel. This type of stainless steel is known to have good strength and high corrosion resistance.

Nuts

Hot Dip Galvanized Grade 2h Nut

Available Ø Sizes

1/2, 5/8, 3/4, 7/8, 1

Just like the Gr 8.8 Nut, this 2H nut is also hot dip galvanized which means it went through a process that will prevent it from corroding. Specifically, this process includes chemical cleaning to get rid of rust, dirt, oil, and other unwanted elements that may have attached to it. The second part is the coating process.

A 2H nut has a medium strength. Its primary uses are for pressure valves and vessels, pipelines, pressure controls, chemical, gasoline, and oil storage systems, natural gas and steam storage, and transmission of chemicals, gasoline, oil, steam, and natural gas.

Basically it’s best for high temperature applications and high-pressure conditions because it’s designed to withstand extreme environment conditions.

A 2H Nut should not be confused with a 2HM Nut. Although they have the same chemical composition, the manner they are tested are different. The former requires only a small sample to be tested while the latter needs the whole population to undergo testing.

The hardness requirements and the proof load between the two also differ. The 2H Nut has a Brinell Hardness minimum of 147 (depending on the size) while the 2HM’s is 159. The proof load of a ½ in. 2H and 2HM are 24, 830 and 21,800, respectively.

Steel Anchors and Expansion Bolts

Expansion Shield

Archives

An expansion shield or expansion anchor is used for very heavy materials needed to be anchored into concrete, brick, or block. They are commonly used when the installation calls for shear load or the bolt will be exposed to vibration and side pressure.

There are different types of an expansion shield, namely, single expansion, double expansion, and lag screw expansion.

Structural members which need anchors to be attached to masonry involves ledger beam, girders, floor and roof diaphragms, and other materials that might need to transfer their load to the masonry. Not only do anchors transfer gravity loads to masonry but they also can transfer lateral loads as well.

There are a variety of applications possible for construction anchors. Typically, they are used to secure objects to materials that are normally resistant to screw or nails, for example, concrete. There are a lot of different types of anchors to choose from depending on your needs.

Anchor bolts are a type of steel anchors that are used to connect structural and non-structural elements to the concrete. The attachment is made through assembling of different components such as anchor bolts, steel plates, and stiffeners. Shear and tension forces are types of load that are transferred by anchor bolts. A plastic anchor sleeve is the go-to sleeve if one wants ease of use and affordable installation of anchor bolts into concrete.

A 4140 steel means it is a low alloy steel consisting of manganese, chromium, and molybdenum. It’s made by combining iron, carbon, and the three elements in an oxygen furnace. The latter are mainly for resisting corrosion. Once these are molten, they are allowed to cool then annealed, a process that involves heating steel at a certain temperature before allowing it to slowly cool down at a controlled rate. This process improves machinability and electrical conductivity.

A 4140 steel has a tensile strength of approximately 95,000 psi, the ultimate tensile strength. It’s known for its ductility, toughness, and hardenability.

Heavy-Duty-China-Nut

An ASTM A325 nut (now ASTM F3125) means the nut has mechanical properties that range from ½ – 1” and 1⅛  – 1 ½”, tensile strength of 120 min and 105 min, and Yield strength of 92 and 81 minutes. It’s almost equivalent to a Grade 8.8 nut rating. It can be made from weathering steel, medium carbon steel, boron steel, and medium carbon alloy steel. 

Nuts are another type of fastener with a threaded hole. Usually, a nut is the counterpart of bolt. Bolts can hold things together tightly thanks to the nuts. Nuts and bolts are used together to clamp two or more parts having unthreaded holes together. The two are kept together by a combination of several factors including the friction of their threads, stretching of the bolt, and compression of the parts that are to be held together.

To simplify, nuts are round discs that have a hole inside them used with bolts to fasten objects. In normal use, a nut-and-bolt joint holds together because the bolt is under constant tensile stress. The tensile stress pulls the nut threads against the bolt threads providing a clamping force that would prevent axial movement. However, when a joint is subjected to vibration, there is a tendency for the nut to easily loosen, therefore, specialized locking nuts are preferred in this situation.

Bolts

Hook Bolt

Archives

A hook bolt is a hooklike steel fastener which is threaded on the straight side and not on the bent portion. The threaded side comes with a nut. Just like a hook screw, a hook bolt is used for hanging items on walls or ceilings. However, a hook bolt can carry heavier loads than a hook screw. Also a hook bolt is better for concrete, blocks, or bricks. It has plenty of applications ranging from hanging frames, house plants, art, and a whole lot more.

Installing a hook bolt requires a pre-drilled hole. Sometimes, a hook bolt requires wooden studs behind a drywall to make it more stable. Washers are added to the mix to make it stable despite vibration or the heavy weight of the item hanged. Other times, an anchor is required to keep the hook locked in place.

The thicker a hook bolt is, the heavier load it can take. To ensure the bolt doesn’t break or the object doesn’t fall, it’s a good idea to distribute the load among many hook bolts. The heavier an item is, the more bolts needed. Springs can also help add strength and security to the bolts.

Bolts

J Bolt

Archives

Unlike u-bolts, J-bolts are j-shaped fasteners. It’s threaded on the “straight” side while the bent end is used as a hook around the rebar for support. J-bolts are commonly used in securing walls to concrete foundations. The bent end may be cast in concrete for use as an anchor bolt.

A U-bolt, on the other hand, is a bolt bent into the shape of the letter “u”. It’s a curved bolt that has threads on each end which makes it fit perfectly around pipes or tubes. A major use of U-bolts is for hanging pipes. Because gravity can be hard on piping, the wrong setup can lead to disaster. By fixing a U-bolt to an overhead structure, beam, or ceiling, the risk of it happening can significantly reduce.

Bolts are one of the most common basic hardware parts you can see in any industry–automotive, construction, agriculture, etc. Bolts definition is they are mechanical fasteners that connect different parts. Its parts include the head and a threaded cylindrical body. Bolts are usually used with washers and nuts to lock them in position and prevent loosening or crushing. One reason bolts are popular across all industries is that it makes assembly, disassembly, and reassembly easier compared to permanent fastening such as welding.
