What Are The Different Types Of Screws?

Screws are very common fasteners, and there are many types of screws, each designed for specific applications. As a professional fastener manufacturer, Xinchi is happy to introduce some of the most common types.

Wood Screws: Wood screws are used for fastening wood and wood-based materials. They have a smooth shank and threads that run along the entire shaft or part of it.

Machine Screws: Machine screws are designed for fastening metal or plastic to metal or plastic. They have a uniform diameter and often require nuts or tapped holes to secure.

Sheet Metal Screws: Sheet metal screws are used for fastening metal sheets to other materials. They have sharp threads that help grip and secure into thin metals.

Self-Tapping Screws: Self-Tapping screws can create their hole as they are driven into materials, so no pre-drilling is needed. They are commonly used in metal, plastic, and wood.

Lag Screws (Lag Bolts): Heavy-duty screws with a large, coarse thread. Lag screws are often used for attaching large wooden structures or securing wood to masonry.

Deck Screws: Deck screws are designed specifically for outdoor decking and wood applications. They usually have corrosion-resistant coatings like zinc or stainless steel.

Drywall Screws: Drywall screws are used for attaching drywall to wooden or metal studs. Typically, it has a bugle-shaped head and a sharp point for easy driving into drywall.

Hex Head Screws: Hex head screws are screws with a hexagonal head that require a wrench or socket to drive them. They’re often used in construction or heavy machinery.

Carriage Bolts: Have a round, smooth head and a square section under the head to prevent rotation when installed. They’re often used for fastening wood to metal.

Thumb Screws: Thumb screws are designed to be tightened and loosened by hand, without tools and typically used for applications where frequent adjustments are needed.

Set Screws: Set screws are used to secure an object within or against another object, often without needing a nut. Usually, they have a cup-shaped or flat end.

Security Screws: Designed with a special head (like a pin or unique shape) to make it difficult to remove with standard tools. They’re often used in public areas or for tamper-resistant applications.
