A sheet metal screw is a type of fastener, usually made of steel, used primarily for connecting thinner metal objects or sheet metal. These screws are characterized by their sharp threads and pointed end, which allow them to easily penetrate and grip into sheet metal and other thin materials. They come in various shapes and sizes, with different head types like flat head, pan head, or hex head, and they can have either a Phillips, flat, or other drive type.
The threads of a sheet metal screw are designed to be self-tapping, meaning they can create their own threads as they are driven into the material. This makes them particularly useful for materials that are too thin to be effectively pre-threaded, as in the case with thicker materials. Sheet metal screws are commonly used in HVAC, automotive, and general metal fabrication applications. They can be found in a range of materials, including stainless steel, for corrosion resistance, and in various coatings for additional durability or aesthetic purposes
Wood screws are specialized fasteners designed for use in woodworking and carpentry projects. They have several distinctive features that set them apart from other types of screws:
Material: Wood screws are typically made from strong materials like stainless steel, carbon steel, or brass, which provide durability and resistance against corrosion. Stainless steel is particularly popular for its strength and rust resistance.
Head Type: Wood screws come in various head types, including flat, round, and oval. Flat heads are countersunk and sit flush with the surface of the wood. Round heads protrude from the surface, providing a decorative finish. Oval heads combine features of both flat and round heads, offering a slightly rounded top.
18-8 stainless steel pan head screws have good chemical resistance and may be mildly magnetic.
Metric 18-8 Stainless Steel Pan Head Slotted Screws
Good for use outdoors and in washdown environments, these metric 18-8 stainless steel screws are more corrosion resistant than steel and nearly as strong. Their pan-shaped head sits nearly flat on the fastened surface, so there’s no need to countersink a hole.
High-Strength 316 Stainless Steel Pan Head Slotted Screws
More corrosion resistant than 18-8 stainless steel screws, these pan head screws have excellent resistance to chemicals and salt water. They may be mildly magnetic.
Steel Pan Head Slotted Screws
These pan head screws are zinc plated for corrosion resistance in wet environments.
Metric Steel Pan Head Slotted Screws
Install these metric pan head screws for a low- profile, finished look—no countersink required.
Nylon Pan Head Slotted Screws
Nylon screws are chemical and oil resistant, nonconductive, and lightweight. Exposure to moisture may cause them to expand.
