What are the main types of self-tapping screws?

Many times, the type of screw you decide to use will depend on the material of the screw. Below are a few different types of these specific fasteners and fixtures, and the materials they are most suitable for.

Round head screws-Although self-tapping screws are usually used for hard materials, if you need to use thinner materials, round head screws may be the best choice. These are the most common screw types. Many times, this kind of screw is used in combination with a washer.
Pan head-If you are using heavy materials, you should consider using a pan head. They are oval in shape with a tapered base, suitable for hard materials.
Flat head-For those "home assembly" type furniture, you may want to consider using flat head tapping screws. Generally, they last longer than the nails and bolts given to you in the home assembly package.
Phillips Heads-Are you working on plasterboard or timber projects? The crosshead may be your best choice. This type of head provides more control and less slippage, which may be helpful if you are using easily damaged materials.
One-way Heads-If you are in a need-type screw that is tamper-proof, one-way head screws may be your best choice of security items. If you want to loosen these screws, you need to use special tools.
For those who do not understand what is needed and the requirements of a specific project, a variety of fasteners and fixtures may confuse them. In addition to these types of screw heads, self-tapping screws also come in a variety of materials, including metal, plastic, and wood. Choose the one that best suits your project.

Security Screws: Safety Is At Risk Even In Small Stuff

In a world where trust is slowly diminishing, we have become frenetic in handling and keeping things that are significant. But Mother Theresa once said, "Be faithful in small things because it is in them that your strength lies." There's passage reminding us that folks who can't be trusted with small things are people who can't be trusted with big things. Perhaps it can also be said that if we can't trust some literally small things, we can be broken big time. Don't discount the small things for it might be the cause for your serious problem. This also applies with household equipment such as cheap stainless steel security screws. Never dare to belittle the function of small tools chiefly if they have great specifications. Thanks to the genius minds behind screws that are designed to hand a superior level of safekeeping than your standard screws or fasteners. Technically, this innovation was created to avoid crimes like theft and robbery. These gears guara...

Self-tapping screw anti-brittle fracture technology is inseparable from heat treatment

Self-tapping screws are often seen in metal plates with relatively thin links (steel plates, saw plates, etc.). Due to the high strength of the threaded surface of the self-tapping screw (≥HRC45), when linking, the self-tapping screw is screwed into the connector that has been made with the threaded bottom hole in advance, so that the inner thread can be tapped in the threaded bottom hole of the link The thread thus completes the connection. There is a special screw that has better working performance than ordinary self-tapping screws and can even replace machine screws-self-tapping pin screws are often used for links between thin metal plates. The difference between it and the ordinary self-tapping screw is the ordinary thread with the arc-shaped triangular interface with higher hardness. This kind of excellent screw with low screwing torque and high locking performance, of course, can also tap the internal thread in the threaded bottom hole to be connected like a normal screw. The wa...

Types and advantages of flange bolts

Flange bolts are integral bolts composed of hexagon head, flange (washer and hexagon fixed body under the hexagon) and screw (cylinder with external thread). Need to be fastened with the nut to connect the two through-hole parts.   The flange bolts can be separated. If the nut is removed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. Flange bolts need to be matched with nuts to fix the two through-hole parts.   There are four types of flange bolts: 1. Types of hexagonal flange bolts: There are two types of hexagonal heads, one is concave head and the other is flat head. 2. Surface color classification: according to different needs, the surface is plated white, army green, yellow, and will never rust. 3. Flange bolt category: according to the position of the flange bolt, the size requirements of the disc will be different. There are also teeth on the bottom, flat, with teeth to prevent slipping. 4. According to the connection f...
