Countersunk Head Slotted Brass Wood Screw

Characteristics and applications of Jiaxing Chishing® countersunk head slotted brass wood screw

Common wood screws can be divided into round head type, countersunk head type and oval head type according to different screw heads.

Prior to the use of traditional wood screws,it is necessary to pre drill holes on the wood mounting parts,otherwise it is easy to cause wood cracking.In addition,because the traditional wood screws do not undergo heat treatment,it is easy to damage the groove shape by screwing with electric tools,and it is difficult to install them manually.Compared with traditional wood screws,countersunk head slotted brass wood screws are more practical and high-quality.

Purpose of countersunk head slotted brass wood screw:similar to machine screw,but the thread on the screw is a special rib for wood screw,which can be directly screwed into wood components(or parts).Generally,countersunk head slotted brass wood screws are polished,which are often used to install hinges, hooks and other hardware accessories.The specification is determined by the diameter,length and nail head type of the rod.

The advantage of countersunk head slotted brass wood screw is that its consolidation capacity is stronger than that of nailing, and it can be removed and replaced,which is less harmful to the wood surface and more convenient to use.

Countersunk head slotted brass wood screw is a kind of nail specially designed for wood.After entering the wood,it will be firmly embedded in it.If the wood is not rotten,it is impossible to pull it out.Even if it is forcibly pulled out,it will bring out the nearby wood.

Countersunk head slotted brass wood screw detection tool:

Both purchasing and sales know that in manufacturing,errors cannot be avoided, and can only be approached infinitely. Therefore,at this time,the quality inspection of screws is needed to improve the quality of screws.

As a manufacturer,we must first detect the wire diameter of the screw wire and the material of the screw.Generally,the wire diameter of the screw is measured with a caliper,and whether it is the same as the size ordered by ourselves.After these tests,it is the test in the production process. Starting from the screw head,determine the head size,head opposite side,diagonal, cross groove depth,screw tolerance range,etc.These are tested with caliper.In terms of all aspects of testing during tooth rubbing,the main ones are whether the tooth thread can pass the go no go gauge,whether the screw thread can pass the go no go gauge, and whether the screw thread can pass the go no go gauge.This is the problem of electroplating measurement.

After electroplating,it needs to be tested by environmental protection testing machine and salt spray testing machine.

In a word,it is necessary to use necessary tools to detect the quality of screws in the process of screw production and sales. The summary is as follows:caliper,hardness tester,salt spray machine,environmental protection testing machine,go no go gauge,etc.

The process is controlled layer by layer, and everyone pays attention to quality.

Coating of Countersunk Head Slotted Brass Wood Screw

Surface anti-corrosion treatment refers to the application of protective layer on the metal surface by various methods.Its function is to isolate the metal from the corrosive environment, so as to inhibit the occurrence of corrosion process,or reduce the contact of corrosive medium with the metal surface,so as to achieve the purpose of preventing or reducing corrosion.

The protective layer shall meet the following requirements:

1.Corrosion resistance

2.Compact and complete structure with small pores

3. Firm combination with base metal and good adhesion;

4.Uniform distribution and certain thickness.

The protective layer is generally divided into metal coating and non-metal coating.The metal coating refers to the protective layer formed on the surface of the easily corroded metal by the metal or alloy with strong corrosion resistance.This kind of coating is also called coating.There are quite a lot of methods and types of metal plating,of which the most common is electroplating,followed by molten metal dip coating(hot dip coating)and chemical surface treatment.

Features of countersunk head slotted Brass Wood Screw zinc plating:

1. Good toughness.

2. Corrosion resistance.

3. Bright and beautiful appearance.

4. High strength.

5. Good quality and low price.

Instructions for the use of Jiaxing Chishing® countersunk head slotted brass wood screws

Tools for installing countersunk head slotted brass wood screw: the screwdriver is its loading and unloading tool,and its shape matches the groove shape of the wood screw head,and there are two kinds of slotted and cross shaped;In addition,There is a

special screwdriver installed on the bow drill,which is suitable for loading and unloading larger wood screws,which is more convenient and labor-saving.Another thing to pay attention to is that wood screws must be screwed in with a screwdriver. Never knock in with a hammer,which will damage the surrounding wood.

Packing method of countersunk head slotted brass wood screws

We usually use bulk,color box,Kraft carton,PC plastic box,PC plastic bucket,tray and other packaging methods.

Of course, customers can also customize.
