Pan Washer Head Square Hole Wood Screw

Characteristics and applications of pan washer head square hole wood screw

The main materials of pan washer head square hole wood screw are steel and stainless steel.

Purpose of pan washer head square hole 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,square drive pan washer head 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 pan washer head square hole 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.

Surface treatment process of pan washer head square hole wood screw:

1. Electroplating: immerse the electroplated parts in an aqueous solution containing the deposited metal compound, and pass the current through the plating solution to precipitate and deposit the electroplated metal on the parts.Generally, electroplating includes zinc plating,copper,nickel,chromium, copper nickel alloy,etc.

Sometimes cooking black (bluing), photostatting, etc.are also included.

2. Hot dip galvanizing: it is completed by immersing carbon steel parts in the plating bath of molten zinc with a temperature of about 510℃.As a result,the iron zinc alloy on the surface of steel parts gradually becomes passivized zinc on the external surface of products.Hot dip aluminium is a similar process.

3. Mechanical plating: impact the product surface through the particles of coated metal,and cold weld the coating to the product surface.

Pan washer head square hole 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.

(1) Quality:Products use high-quality materials to ensure quality. We have a professional QC team to inspect every project from production to packaging.And before leaving the factory,all specifications of products are sampled and tested to ensure stable quality.We guarantee the high-quality coating and low roughness of screws.

(2) Product features:Straight,not easy to break,sharp thread, good drill ability.

(3) Strict quality control:For each order,the quality control department will conduct strict inspection before delivery.Poor quality will be avoided in the door.

(4) Transportation:We have transportation department and freight forwarder,so we can ensure faster delivery and better protection of goods.

(5) Efficiency:Fast production time,only 260 minutes away from the nearest Shanghai port.

(6) Service:Customer service answers customer questions online 24 hours a day,and uses high-quality materials to ensure quality.

PS:Many screw specifications and screw models are based on national standard specifications and models. Generally,such screws are called ordinary or standard screws.Some non- standard screws are not based on national standard specifications and models.They are customized according to the standards required by product materials, and there is no stock. In this way,we have to customize the drawings and samples, which takes a long time.
