Small screw with cross hole for embedded seat nut

Small screw with cross hole for embedded seat nut

This is a screw that incorporates a washer used to prevent loosening and to avoid the sinking of the seat surface. The screw threads are roll-formed with the washer in place, ensuring that the washer does not come off the screw. This eliminates the hassle of inserting the washer, prevents it from falling out, and helps improve work efficiency. The pan head is the most commonly used representative shape, and its height allows the screwdriver to fit securely into the cross slot. It is used in various places, including electronic devices and bicycles.

Binding screw with cross hole for embedded seat.

Binding screw with cross hole for embedded seat.

Binding screw with cross hole for embedded seat nut

This is a screw that incorporates a washer used to prevent loosening and to avoid the sinking of the seat surface. The screw threads are roll-formed with the washer in place, ensuring that the washer does not come off the screw. This eliminates the hassle of inserting the washer, prevents it from falling out, and helps improve work efficiency. The head is shaped like a combination of a pan and a truss, with a diameter about 1.2 times larger than that of a pan head screw of the same nominal size. It is sometimes used when the head diameter is too large for a truss. Like the pan head, it is a small screw that can be used widely. A typical example of its use is the fastening of wires inside a power plug.

Truss screw with embedded cross hole for seat nut

Truss screw with cross hole for embedded seat nut

This is a screw that incorporates a washer used to prevent loosening and to avoid the sinking of the seat surface. The screw threads are rolled with the washer in place, ensuring that the washer does not come off the screw. This eliminates the hassle of inserting the washer, prevents it from falling out, and improves work efficiency. The truss head has a rounded shape, resembling the top of a sphere that has been cut off. It is lower in height and has a larger outer diameter compared to a pan head. Its large contact area allows for effects such as preventing loosening. Additionally, because it has an aesthetically pleasing appearance, it is often used as a decorative screw in home appliances and office furniture, with surface treatments to match colors and finishes.

Set screw with cross hole for embedded seat.

Set screw with cross hole for embedded seat.

Seat bolt with cross hole and upset small screw

This is a screw that incorporates a washer used to prevent loosening and to avoid the sinking of the seat surface. The screw threads are rolled with the washer incorporated, ensuring that the washer does not come off the screw. This eliminates the hassle of inserting the washer, prevents it from falling out, and helps improve work efficiency. The head is formed into a hexagonal shape through cold forging, and typically has a recess on the top surface. At first glance, it looks like a hex bolt, but it also has a cross hole, allowing it to be tightened using various tools such as screwdrivers, wrenches, and spanners. Due to this advantage, it is suitable for places where the frequency of attaching and detaching is relatively high and where multiple people need to attach and detach it. It is commonly used in automobiles and other applications.

Seat screw with cross hole and washer.

Seat screw with cross hole and washer.

Screw with cross hole and embedded seat.

This is a screw that incorporates a washer used to prevent loosening and to avoid the sinking of the seat surface. The screw threads are rolled with the washer in place, ensuring that the washer does not detach from the screw. This eliminates the hassle of inserting the washer, prevents it from falling out, and helps improve work efficiency. The head has a flat top and a conical seat shape. When measuring length, the length of a pan head screw is measured from the top surface, while other screws measure from the neck down, making it appear shorter. It is used when you want the head to be flush with the component without any protrusion. The component must be pre-machined with a conical recess to match the seat surface. If this machining is insufficient, the head will not be flush. It is commonly used for the installation of building fixtures, with hinge fastening being a typical example.
