Differences In Common Fasteners

Fasteners have been widely used in various places, among which bolts and screws are our most common fasteners. And for these two common fasteners, a lot of people will confuse them. As a professional fastener supplier, Xinchi Fastener Company is glad to share the difference between bolts and screws.

The obvious difference between a bolt and a screw is the head. There is only an ordinary hex head in the hardware tool manual called bolts, the rest of the hex, countersunk head, and round head are called screws.

Structural differences: bolts have a variety of styles of “head”; Studs without “head”; Screws also have a variety of “heads”. But the structure of the head is different. The head of the bolt is mostly hexagonal, generally large; The “head” of the screw is generally equipped with fastening slots (slot, cross slot, etc.), internal and external hexagons, etc. The screws that can be tightened by hand will be rolled on the “head”, which makes the size of the screws smaller.

Differences in application: bolts and nuts are generally used in pairs for through holes, easy to replace after damage.

Bolts are also commonly used in conjunction with nuts because individual bolts do not connect. Bolts are mostly used for blind holes. Tools generally use a wrench, and the connected parts need to be removed often.

Screws usually do not need nuts, and directly fit with the two objects (general connectors should be drilled and tapped first). Screws are also used for blind holes, tools generally use a screwdriver (screwdriver), and the connector is often removed.

The difference between screws and bolts is the smallest. Generally, the tapping screws are mostly called screws, such as self-drilling screws, tapping screws, wood screws (lag screws), etc. Larger screws are called bolts, such as hex machine bolts, expansion bolts, carriage bolts, etc.

After reading these differences, you may not be able to tell a bolt from a screw. But in real-life work, we can clearly recognize whether it is a bolt or a screw.
