Bolts are typically used in conjunction with nuts (often with one or two washers) and play a vital role in situations where they are required for connecting and tightening. Bolts come in a variety of types, including hex head bolt , hex flange bolt , wheel hub bolts , hex socket bolt , carriage bolt, hub bolt , square head bolt , double-ended bolts , T-bolt , steel bolts , U-bolt, eye bolt , Anchor bolt , etc., and they are key components in mechanical assembly.
Nuts are used in combination with bolts and are available in various shapes and sizes, such as Round nut , Hexagon nut , Flange nut , square nut , Guard nut , other loose nut , Cap nut ,Furniture type nut ,etc. They are essential components for achieving fastener connections, ensuring the solidity and reliability of the connections.
Screws are generally used alone (sometimes with washers) and are primarily used for tightening or securing parts. They can be wood screws , machine screws , self-locking screw , or self-tapping screws , chosen based on the material and application scenario.
Studs are long rods with threads on both ends, typically with one end fixed inside a component and the other end mated with a nut for connecting and tightening. Studs are widely used in automobiles, construction, and heavy machinery.
Washers are placed between the supporting surface of bolts, screws, nuts, etc., and the surface of the part being supported to prevent loosening, reduce stress concentration on the supporting surface, and protect the surface of the parts.There can be Flat washer , Gasket , Spring washer , Retaining ring , Locking washer .
Self-tapping nails can form internal threads when screwed into a workpiece without the need for pre-tapping. These screws are suitable for connecting thin metal sheets and wood,there have Cross recessed tapping screws , Triangle teeth self-locking screw , Drywall nails Fiberboard nails , Hexagon head tapping screw , Wood screws Cement steel nails , Quince-slotted tapping screws , Slotted self-tapping screw .
