Wedge anchors allow you to secure concrete when a hole is drilled into the concrete and the anchor is inserted.

Hadn't seen these before. These are used to connect wood or metal to concrete. The long end screws into the concrete and the short end acts as a nut for a bolt going through the other material.

A Dowel Screw has threads on both ends and a square section in the middle that lacks threads. You would use a dowel screw to fasten two objects together and is typically used with wood and in the making of furniture. To insert the dowel rod you must first drill a hole that is slightly smaller than the dimensions of the dowel screw and a bit shorter than the length. After the hole is drilled you could use pliers to tighten the screw in place by gripping the dowel screw in the middle where there are not any threads. You could connect the other material onto the exposed end of the dowel rod by twisting in into place. Dowel screw make for a strong connection between two softer materials.

UHO

I have never seen this type of level before. It is used to plumb and level posts. It would come in handy when you are putting in posts for a deck or fence. You use it by holding it on the corner of a post and making sure the bubbles are in between the lines. 

Headless (Blind) Stainless Steel Set Screw

 

        

Set screws are generally used to secure an object by using compressional or clamping force.  There are different types of point styles available: the most common point is a cup point and is used for quick, permanent and semi-permanent part assemblies; the flat point is used for frequent relocation of parts where minimal shaft deformation is required; the half dog point is often used in place of a dowel pin; the cone point has the highest torsional and axial holding capabilities; and the oval point is used when the point meets the part on an angle. 

Usually, set screws are used to secure a pulley or gear to a shaft.  Most set screws are headless, meaning there is no head projecting past the screw thread.   To fasten two objects in place, a blind set screw is driven through a threaded hole in the outer object and is tightened against an inner object to prevent it from moving relative to the outer object. Often, but not always the friction created by fastening the screw can cause some elastic or plastic deformation of one or both objects.  In the UK the headless set screw is called a grub screw, most likely because of its resemblance to a grub.

UHO: 6L Hole Saw Arbor

The people at Lowe's were pretty busy when I was there so I just took this picture and left. I looked this thing up online, even though I could only read half on the name on the package because of the glare in my photo. Anyway, I figured it out. It is a 6l Hole Saw Arbor. A hole saw is a drill bit that is used to drill large holes. It consist of a middle part that called an arbor that is shown here and a removable hole saw that is a cylindrical saw that attached to the arbor. The arbor is the part that attaches to the drill, holds the hole saw and has the pilot bit. The pilot bit is the drill bit you see in the picture. The pilot bit helps to start the drill and hold it in place while the hole saw cuts the larger diameter hole on the outside. As far as the 6L specification goes as far as I could tell its means its a larger size bit. The other size options were 2L and 5L. Hardware Identified.

UHO:multigrip rivets

Multigrip rivets:

There are several different kinds of rivets but you may be asking, what is a rivet? A rivet is a s short metal pin or boltlike hardware that functions to hold two pieces of metal together by being pressed into place, usually by a riveter. One kind of a rivet is a multigrip rivet which does the same thing as a normal rivet except a multigrip rivet has a wider gripping range than the standard ones. Why is this useful? When you use a multigrip on a larger hole or one that is a weird shape, it ensures that the hole is filled. Also, when you use a multigrip rivet is a stronger connection because it has a higher clamping force and is vibration resistant. This kind of a rivet is used for heavier duty projects.
