Carriage Bolt Assembly

Back 1

Threaded fasteners with a bolt that has a rounded, dome-shaped head. The bolt has a square neck that extends from the head towards the threads. A regular hex nut or wing nut allows the assembly to hold the components together. This assembly can be tightened with just one wrench.

Carriage bolt assemblies are commonly used in carpentry and construction; they are well-suited for fastening two structural wood pieces together, especially when extra strength is required. The square neck sinks into the wood as the fastener is tightened, preventing the bolt from turning and countersinking the bolt head at the same time.

Eye Bolt

Back 2

An eye bolt is a screw with a loop on one end and threads on the other end. Eye bolts are commonly used to attach cables to objects, for instance attaching a string to the back of a painting to allow the painting to hang from a nail on a wall.

Eye bolts made by bending a rod or wire into a loop are only suitable for light duty applications, as heavy loads can cause the eye to open. For high loads, eye bolts with forged or welded loops should be chosen, as they can withstand loads up to the tensile strength of the material of which they are made.

Anchor bolt

Back 4

An anchor bolt is used to attach objects or structures to concrete. There are many types of anchor bolts, consisting of designs that are mostly proprietary to the manufacturing companies. All consist of a threaded end, to which a nut and washer can be attached for the external load.

Lag Bolt

Back 6

Lag-bolt heads are meant to be driven with a wrench or a ratchet and socket. Before driving a lag bolt, pre-drill a pilot hole about two-thirds the bolt’s length using a drill bit that is 1/8 inch smaller than the lag bolt’s shank. Slide a washer onto the lag bolt before driving it in.

Lag Bolt with Expansion Shield

Back 7

The term expansion shield is used to describe a masonry anchor that requires the use of a bolt, lag screw or setting tool to expand the anchor once it is placed in a hole in the base material. Other than epoxy type and concrete screws, all other concrete fasteners use expansion as a means by which their holding values are derived

Lag Bolt with Fiber Plug

Back 8

The Fiberplug is a jute fiber screw style anchor designed for use in concrete, block, brick, and stone.The Fiberplug is an anchor designed for use with wood,
sheet metal, and lag screws. It is formed of braided jute fiber which is bound into a tubular shape.A lead lining on the sheet metal and wood screw sizes
makes it possible for the screw to reproduce its own thread, and keeps the jute fibers from being cut by the screw

Front 9

Lag Bolt with Lead Shield

Back 9

Lag shields are medium-duty anchors which expand to fill the area of the pre-drilled hole when a lag screw is tightened into the shield. Extra-long sizes are for use in mortar or brick. Standard lengths are intended for use in concrete. They can be used in solid or hollow material and are more resistant to temperature fluctuations and rust than other light-duty anchors

Machine Bolt Assembly

Back 10

A machine bolt, also known as a hex bolt, is a square or hexagonal head. The body or nut of the machine bolt consists of threading and a smooth shoulder; however, shorter bolts may be fully threaded.
