Bolts for Virtually Any Use
At Fastener SuperStore, Inc., we offer multiple bolts for sale so that you will have what you need, regardless of the type or scope of your project. Here are a few common uses for the bolts we carry:
- Carriage bolts are self-locking when paired with a square hole in a metal strap. This is a useful feature for installation from one side.
- Dowel screws are fully threaded on both sides, making them very effective at securing two pieces of wood together, such as with furniture.
- Elevator bolts are made to secure canvas belts in conveyor systems. They are common in grain elevators and other similar systems.
- Hanger bolts are specially made to suspend objects from a wood base. They come in fully threaded or plain center options.
- Hex cap screws are made for use in such applications as original equipment manufacturing when a tight tolerance is required.
- Hex flange and frame bolts are commonly used in vehicle frames.
- Hex machine bolts are commonly used in decks and other outdoor applications.
- Hex tap bolts are useful for machinery applications, such as in motor assembly.
- Lag screws and lag bolts have sharp points for easy use in wood surfaces.
- Metric bolts are sized differently than US standard bolts and are commonly used in machinery. You'll find many metric sizes on bolts.
- Plow bolts are similar to carriage bolts. They are made with a countersunk head for a flat finished surface.
- Slotted flat head cap screws are designed with countersunk heads, making them good for applications that require perfectly flush surfaces.
- Square head machine bolts are used for the same applications as standard hex bolts but are increasingly common for use in both machinery and wood.
- Step bolts are common in wooden decks because they are smooth and nearly flush.
- Structural bolts are heavy-duty bolts made for use with nuts to connect more than one structural member.
- Threaded rods/studs are threaded throughout their length for sturdy use in tension applications.
