Screws and Their Uses

Fastener SuperStore, Inc., is your best bet when you have to buy bulk screws for practically any application. Here are some of the most common uses for various types of screws that we carry:

• Concrete screws are incredibly tough and made specifically for firm placement in concrete and masonry. They are excellent for use in heavy-duty construction when something has to be anchored to a cement wall or foundation.
• Deck screws are made for exterior wood jobs, especially decking and other outdoor builds. They hold well in pressure-treated lumber and stand up better when the weather keeps changing.
• Drywall screws are specially made to hold securely in drywall or other typically weak surfaces, though they also can be used in wood studs.
• Lag screws are heavy-duty fasteners for wood, used when a connection needs real strength. You’ll see them on beams, posts, ledgers, and other load-bearing lumber where standard screws aren’t enough.
• Machine screws are used with size matched nuts for attaching metal parts and materials.
• Metric screws are sized differently than US standard screws and come in several different styles.
• Self-drilling screws are ideal for applications in which you need to fasten materials without pre-drilling a hole.
• Self-piercing screws, like self-drilling screws, are made to go in without a pilot hole. They’re often used in metal roofing and siding where speed matters and you’re fastening sheet to framing.
• Self-tapping screws are also called sheet metal screws and are used across HVAC, enclosures, light fabrication, and general assembly.
• SEMS screws are preassembled with a free-spinning lock washer. These screws are perfect for applications that require a washer, saving on installation time.
• Serrated hex flange screws are used in applications that require firm locking of the screw itself.
• Thread-cutting screws have a sharp cutting tip that creates threads in wood, plastics and metals not already threaded.
• Thread-forming screws, also known as Thread Rolling Screws form their own threads and are best used in thinner materials.
• Thumb screws are made to be easily secured by hand.
• Weld screws are used when a threaded fastener needs to be permanently attached to a metal surface before assembly.
• Wing screws are meant for finger-tight installs, which makes them a good fit for parts you adjust or remove often.
• Wood screws are intended for fastening wood to wood in general construction and carpentry.
