Fasteners play the main role in the build of all sorts of everyday objects. If you have done any do-it-yourself you have likely utilized fasteners to help get the job done. At All Points Fasteners, we are committed to the role quality fasteners can play for handy residents and professionals alike. Let’s take a moment to explain fasteners and overview some of the different types, as well as the different uses for them.
What Is A Fasteners?
Let’s begin by explaining what a fastener is. Fasteners are tools like screws, nuts, and bolts that all have one job in common: holding things together using mechanical means. While glue can also stick things together, it does not count as a fastener. So, to make it clear, hardware fasteners are tools that mechanically keep objects connected.
Fasteners form a non-permanent joint. In other words, when you utilize a fastener to connect two components, you can remove it, and the separate pieces they hold together should be able to come apart without getting damaged.
The same would not be the case with a welding joint for instance. The one exception to this rule is rivets, which fall under the category of fasteners but create permanent connections. Though most fasteners form a non-permanent connection, this doesn’t mean you only utilize fasteners when you want to be able to take something apart & it doesn’t mean the connected is weak by any means.
Fasteners are reliable in holding together objects that can experience a great degree of stress. It means they are a great choice for permanent and non-permanent connections such as providing versatility for the type of project you want to utilize them for.
Types Of Fasteners
Mechanical fasteners come in various types. Every one of those kinds also has many subtypes that you can select from. Among the various types of fasteners, here are we discussed the most common ones:
- Bolt: These kinds of fasteners help to hold two unthreaded components together. often referred to as the most prevalent fastener types.
- Nuts: A nut comes with an internal thread that works with a bolt to hold parts together.
- Washers: They are tiny, round disks that look like rings. They team up with nuts and bolts and serve important fastening functions.
- Screws: When people talk about things that hold stuff together, The screws are the first choice to come to mind. Screw fasteners are one of the main versatile kinds of fasteners out there. Their twisted shafts provide a strong grip, and unlike a bolt, they don’t require anything to hold them in place. Usually, you use a drill to make a starting hole in the material and then a screwdriver to twist the screw in. There’s a bunch of different screws in all sorts of shapes and sizes in the world.
- Rivets: These are permanent fasteners that assist secure several different kinds of components.
- Anchors: The anchors get their name due to they serve a similar function to a boat’s anchor, which embeds itself in the seabed area to keep a ship from moving. People utilize these fasteners to connect something to a material such as drywall or concrete. They stud themselves in the material and grip the object you are affixing in areas.
- Nails: Nails have been employed since ancient times, and they remain a common household item. Distinguishing between a screw and a nail is straightforward, as a nail lacks threading. Although a nail does not provide the same gripping capability a screw does, it has superior shear strength, making it the preferable option for some applications.

What is Concrete Anchors
Concrete anchors are tools that help join things securely to the surface. They are strong hooks and connectors that keep objects in place & next them from moving. people use them in different palaces like construction to make sure things shelves equipment and structures stay attached to the concrete.
These anchors manufacturers of tough materials such as steel. Installing them involved drilling into the concrete & using a bolt or screw to attach anchors. They offer a reliable way to attach things to concrete.
Types of Concrete Anchors
1-Machine Screw Anchors
The masonry anchors are inserted into pre-drilled holes in masonry materials. After being positioned inside the hole, a machine screw is threaded into the anchor and securely tightened. As the machine screw is tightened,the conical section is drawn into the sleeve causing it to deform.This deformation of the sleeve creates a secure wedge inside the hole that cannot be easily removed.
2-Sleeve Anchors
The concrete masonry sleeve anchors comprise a threaded stud with a Visibly flared cone-shaped end, together with a nut & a washer on the end. The tightening of the nut draws the stud end into the expander sleeve, wedging it outwards and locking the anchor into the base material. Specifically made for hollow concrete applications such as cinderblocks.
3-Plastic Toggle Anchors
The plastic toggle anchors are utilized in hollow walls or cinder blocks to make a fastening point for sheet metal screws. The legs of these anchors can be folded to fit into a pre-drilled hole and then expand when a screw is inserted. Once the legs are completely expanded, the toggle anchor is firmly in position.
4-Wedge Anchors
The concrete masonry wedge anchors are utilized to anchor and secure material and equipment to solid concrete masonry surfaces. Comprised an anchor, a nut & a washer. Utilized to fasten concrete to equipment, materials, generators, motors, pumps, pipes, struts, plastics, and wood.
5-Masonry Screws
The concrete masonry anchors also called Tapcons, cut threads into concrete, brick, or block during installation. Extended corrosion safety is gained from the blue climate coating. Hole no spotting or inserts are needed.
6-Drop-In Anchors
The Drop-in anchors are internally threaded anchors that are installed overhead & flush with the surface of the concrete. These anchors are basically utilized to create handrails, lighting fixtures, and many different fixtures. They need a setting tool for installation.
7-Acoustical Wedge Anchors
Masonry acoustical wedge anchors are utilized to anchor and secure suspended wire to solid or hollow masonry materials. The fastener is introduced into the pre-drilled hole & then struck with a hammer which dilates the wedge to hold the anchor in place.
8-Hammer Drive Pin Anchors
These anchors are utilized for lower loads than other kinds of concrete anchors. Drive pins jointed fixtures to masonry materials. The hammer driven is into the exposed head of the drive pin.
9-Lag Shield Expansion Anchors
These anchors are shielded expansion anchors utilize to hold lag screws. These are expanded outwards as lag screws are driven into them. This expansion presses against the setup surface making a tight, secure hold. They also have precise internal threading to enable the installation lag bolt to turn easily.
10-Double Expansion Shield Anchors
The Double expansion shield anchors are created for installation in softer materials or those of better quality. Their hole length expands in the hole to make a very secure hold. This expansion maximizes friction & holds onto the installed material.
10-Sammy’s Screws
The Sammy Screws are utilized with threaded rods and save time by drilling into materials. They have a female threaded portion to accept the threaded rod into it. Sammy’s are installed either vertically or horizontally and are basically used because of their lower installation costs, flexibility, and ease of utilization.
11-Toggle Wing Hollow Wall Anchors
The Toggle Wings are utilized in situations when installing via a material. The wing should be bent in half and pushed via the material. Once it is via the material it expands and can be screwed into to holding things in place against the rear side of the material.
12-Kaptoggle Hollow Wall Anchors
The Kaptoggle hollow wall anchors are installed via a hole in the walls or block. Then a machine screw is screwed into the offer threading resulting in a secure hold. Kaptoggle wall anchors are proven to have good-holding power than conventional kinds of hollow wall fasteners.
