What Is a Small Pan Head Screw?
A small pan head screw, pan head machine screw, pan head Phillips screw, and cross-recessed pan head machine screw, are all small pan head screws. The head of a small pan head screw is called a small pan head screw because it looks like an overturned pot.
A small pan head screw is generally used for fasteners with female threads or tightened with nuts. Therefore, the threaded end is flat, not "pointy" like a tapping screw. In addition to being used as small pan head screws, they are often used in combination with metal washers.
The terms "cross-hole small pan head screw" and "pan head screw" are also used as synonyms.
The standard for small pan head screw is as follows:
- ANSI/ASME B 18.6.3 Machine Screws, Tapping Screws Metallic Drive Screws
Uses of Small Pan Head Screws
Uses of small pan head screws are extremely versatile and are used in a wide range of applications, from industrial machinery to home appliances and toys.
A small screw has a round head and a Phillips (cross-shaped) tool hole in the screw head, and screw sizes range from M2 to M8. In contrast, bolts have a hexagonal or square head shape, use a tool that fits the external shape of the screw head, and most have a screw size of M8 or larger. (There are also bolts with smaller thread sizes of less than M8.)
Principle of Small Pan Head Screws
Small pan head screws are the same as an ordinary hexagonal bolt, and is fastened to a fastened object by a screw ("screw" in this case refers only to the screw-like shape). Small pan head screws are often used to fasten directly by screwing into a tapped female thread without using a nut.
Small pan head screws are tightened by inserting a Phillips screwdriver (a screwdriver with a cross-shaped tip) into the cross-hole, rather than by inserting a wrench into the bolt head as with a hexagonal bolt.
Compared to countersunk screws, small pan head screws can be made with a deeper cross-hole head, allowing the tip of the screwdriver to engage the cross-hole and provide stable and strong tightening force.
The small pan head screw has two types of screwdriver insertion holes: the cross-shaped "plus" type and the mixed "plus/minus" type.
The length of small pan head screws is indicated by the length of the shaft, including the threaded part, excluding the height of the bolt head, in the same way as the length of ordinary bolts such as hexagonal bolts.
Other Information on Small Pan Head Screws
1. Main Materials and Surface Treatment of Small Pan Head Screws
Small pan head screws made of steel, iron, carbon steel, stainless steel, and brass are commonly used. Aluminum and titanium are also used as other metals.
Polycarbonate and nylon are also available as plastic materials.
In selecting the material of small pan head screws, it is important to prevent electrical corrosion. When the bolt material and the material of the object to be fastened are different, a potential difference between the two metals can cause corrosion. Particular attention should be paid to aluminum and stainless steel. For more information on electrical corrosion, please refer to the following references.
For surface treatment of small pan head screws, electroplating, electroless plating, anodizing, black dyeing, etc., are generally applied for the purpose of corrosion resistance when the screws are made of steel.
2. Proper Use of Small Pan Head Screws
The basic principles of proper use of small pan head screws are as follows.
- Tightening force must be within the allowable range so that the threaded hole between the small pan head screw and the object to be fastened will not be broken.
- The repetitive force (due to vibration, etc.) applied to the threaded hole between the small pan head screw and the object to be fastened must be within the allowable range.
3. Loosening Prevention of Small Pan Head Screws
To prevent small pan head screws from loosening, use an adhesive to prevent loosening, or use bolts that have been treated to prevent loosening.
4. Tightening Tools
To tighten small pan head screws, use a Phillips screwdriver or other tightening tool appropriate for the size of the cross-hole in the head.
