Introduction for chipboard screws

Are designed by the pan head with philip drive , full threads and flat point . working together with a hex nut

Application

1. Car industry

Nylon material is good heat and corrossion resitance and strong tension and convienet to process , almost every part of the car needs it like speack louder , cooling fan , handle , bracket , belt and window etc .

2. Electronics

Nylon material can be used for pieces that must to be conduct insulativity , precise electronics equipments , lighting and so on , and also for electric cooker , electric vacuum cleaner and food heater etc . and for lighting , switch , junction box and wire clamp etc .

3. Mechanical equipment

Nylon material is widely used for train , truck and vessel etc like insulative washer , shaft , nuts , bolts and gears and so on .

4. Daily necessities

There are many items in our life will be used nylon like mirror , comb and water tub and so on .

5. Building

Nylon ( PA) is used to window , door and fence and block

Advantages

Tips for use

1. Use a hex socket to drive the screw .

2. The thread moving direction is from right to left to drill into workpiece , and back out in reverse direction .

3. Do not use a sharp tool or bladed tool to drive the screws .

4. Do not scratch the screw in harden something in order to keep bright surface .

5. Keep the screw in the dry warehouse .

Material introduction

Nylon material is widely used for verious fileds as outstanding performance and best cost , and there are several kind models under the nylon material .

1.PA66

High fatigue strength and rigidity , good heat resistance , low friction factor, abrasion resistant, but weak in hygroscopicity . which is used for moderate load requirement and working temperate less than 120 degree .

2. PA6

It is inferior for PA66 on fatigue strength and rigidity , but is more good on flexibility and reduce noise and weakning . which is used for light load requirment and 80-100 degree working temperature .

3. PA610

It is inferior for PA66 on fatigue strength and rigidity but good hygroscopicity and abrasion resistant . which is used for precise equipment and the pieces where with large change for the temperature .

4. PA1010

It is not good than PA610 in hygroscopicity but easy to process and perfect abrasion resistant . which is used for where moderate tmeperature with various changes of moisture and less or no lubrication .

5. MCPA

It is superior for PA66 and PA610 on fatigue strength and rigidity and heat resistance , but is inferior for PA66 or PA610 on hygroscopicity , which can be used directly for casting to be formed and with large load requirement .

Quality control

(1) Checking material before feed in

all material must be checked according to the requirements of products before put them onto the machines to ensure material is available .

(2) IPQC ( by handle and auto-machined control )

The semi-finished products must be checked in special tools during production , this ensure products are always under control .

(3) Chemical elements analysis and fhysical testing after post treatment

The most metal products need post treatment after finished proudct, all products will be tested after than to make sure the quality of products are meet the related requirement .

(4) The second inspection , sort all finished goods by sorting machines if required ;

All goods were finished , they must to be tested and checked before package ; In this phase , goods will be checked in full inspection or partial inspection . and checking methods can be by handle or auto-machines .

(5) Packing

Packed in polybags and cartons or in small color bags .

(6) Last inspection ( spot checking , packages status , quantity etc )

When all goods are ready , we will make a final inspection for quantity and package’s status .

(7) Delivery

Everything is ready , we will deliver goods to appointed place or port according talking
