Male Thread Type Knurled Head Screw High Precision For Medical Device Manufacturing

Customized of high precision Stepped male thread type knurled hand screw for Medical device manufacturing

Knurled screws:
Knurled plastic screws are specially designed for hand-tight operation. The straight knurling of the head acts to increase the friction, which makes the hand screwing more efficient. In addition, the head also has a slot. It is installed with a flat-blade screwdriver and is mainly used in the display industry, white goods, brown goods, telecommunications and data communication, automotive industry and other equipment that require insulation and frequent disassembly and maintenance.

JESENTECH

is a fastener manufacturer that produces and processes non-standard shaped shafts.

Application areas:
Knurled screws have high-quality properties such as insulation, non-magnetic, corrosion-resistant, beautiful, never rust, and modified engineering plastics, its use strength, impact resistance and metal are comparable, we often say plastic screws commonly known as nylon screws With the addition of 30% glass fiber, its mechanical properties are far superior to ordinary nylon. The materials used for knurled screws are increasingly diversified, the performance is continuously improved, and the application fields are becoming wider and wider.
1. Medical device industry (insulation, non-magnetic, environmental protection, anti-interference, making medical machinery and equipment safer)
2. Wind power industry (isolation and insulation of PCB circuit board)
3. Aerospace industry (insulation and anti-interference on electronic equipment)
4. office equipment industry (never rust, beautiful and practical)
5. Petrochemical industry (high temperature resistance, chemical resistance, corrosion resistance, and extended equipment life)
6. the electronics industry (insulation, anti-interference, light weight)
7. the communications industry (insulated, non-magnetic, security)
8. the ship industry (acid and alkali resistance, corrosion resistance, extended service life) and so on.
The specifications of the knurled screws are complete in size to meet the needs of different occasions.

Material:
Knurled screws are divided into nylon 66, nylon 6 plus 30% glass fiber, stainless steel, carbon steel and so on.
PA66 [Nylon 66]
PA66 (polyamide 66 = nylon 66) is a crystalline engineering plastic. It is a high toughness material with a low coefficient of friction, wear resistance and excellent self-lubricating properties. It is also very resistant to oil and chemicals, so it is most suitable for use as a mechanical material, but there is also a problem that due to its high hygroscopicity, it must be considered in design. Moisture as a plasticizer reduces the pulling of nylon. Stretch strength, gas permeability and improved ductility, impact strength and energy absorption. The outdoor weatherability of nylon can be improved by adding carbon black during injection molding. At most temperatures up to 85 ° C, nylon products Still working for a long time. The color of the nylon material is translucent grayish white.
·6 substances (lead, cadmium, mercury, hexavalent chromium, PBB, PBDE) not limited by RoHS directive
·Continuous use temperature 85 ° C
·Combustibility UL94 V-2
Improved impact resistant nylon 66
Improved impact-resistant nylon 66 has the added advantage of resisting strong impact at low temperatures, heat resistance is much better than ordinary nylon 66, and the modified impact-resistant nylon 66 is grayish white.
Add 30% glass fiber nylon 66.
Nylon 66 with 30% glass fiber added has far superior mechanical properties than ordinary nylon 66. Compared with the ordinary nylon 66, the following aspects are improved: the tensile strength, the deformation temperature and the shear strength are improved, the creep resistance, the dimensional stability are improved, and the water absorption and the thermal expansion type are lowered. Nylon 66 with 30% glass fiber has good abrasion resistance, and the related electrical properties and low friction coefficient of nylon 66 are retained. The color of nylon 66 containing 30% glass fiber is opaque tan.
