There are numerous different types of fasteners. To make it simple for you, we’ve gathered the information below as a reference for identifying the names of each fastener. Learn about various fasteners bolts, nuts, and screws by scrolling down!
Let’s get started,
- Carriage Bolts
It has a domed or countersunk head and is referred to as a “coach” bolt. When the nut is tightened, the square piece beneath the head grabs the fastened object and prevents the bolt from rotating.
- Machine Screws
A flat-pointed screw or bolt is referred to as a machine screw. They are suitable for a wide range of applications, are offered in various drive types and heads, and are frequently pushed into tapped holes. Stove bolts, often known as “stovers,” are used with nuts and washers.
- Socket Cap Screws
There are four socket cap screws: flat socket, button socket, and socket cap. Driven with a hex Allen key or a socket wrench. A threaded fastener whose head diameter is nominally 1.5 times or greater than the screw shank diameter is generally referred to as a “socket head cap screw.”
- Deck Screws
For easier installation in wood and composite deck materials, our deck screws have a type 17 point (notched point at the tip) to help with chip removal during thread cutting. The stripping effect that can occasionally be present with other drives is reduced using a bugle head and square drive.
- Sheet Metal Screws
Sheet steel screws (SMS) have sharp cutting threads that reduce into sheet steel, plastic, or timber. They have a threaded shank and now and again have a notched point on the tip to resource in chip removal throughout thread reduction.
- Cap Nuts
The hat nut, also called the acorn nut, got its name from its shape. The top of the nut is domed to prevent contact with the external threads.
- Flange Serrated Nuts
A flange nut has a large flange at one end that serves as an integrated, non-moving washer. The serrated flange generates a locking action to prevent loosening by distributing the nut’s pressure over the fastened object.
- Hex Finish Nuts
Hex finish nuts are used to secure a bolt, socket cap screw, or hex cap screw. Hex finish nuts, the most popular type of nut, have internal threads in a hex form and are driven with a wrench.
- Hex Machine Nuts
A machine nut has internal threads and a hex form. They are used with machine screws under 1/4″ in diameter and smaller than a hex jam or hex finish nut.
- Keeps-K Lock Nuts
A keeps-k lock nut has an attached free-spinning lock washer and is also known as a Keps nut, a knot, or a washer nut. Keep nuts are created to make assembling simpler.
- Knurled Thumb Nuts
A knurled exterior surface, as opposed to a hex, is present on a thumb nut or nut with a knurled head, which makes it easier to tighten by hand. Frequently used in aesthetic applications or finishes.
