JX-21QJG40-M4-6-ST, M3 M4 M5 M6 Nickel Plated/Black Zinc Knurled Step Thumb Screws Tool-less Manual Micro Adjustment Screws

Screws come in many styles and types, and step screws are no exception. Step screws include cross-recessed step screws, non-standard step screws, stainless steel step screws, internal hexagon step screws, external hexagon step screws, stainless steel hexagon step screws, and more. Each type of screw has different applications and uses.

1. Step screws refer to non-standard screws with two or more steps, which we call step screws. These screws are not stocked and can only be obtained through mold production. As hardware fasteners that are directly hammered into workpieces, step screws have the functions of hammering, locking, and fastening.

2. Step screws are suitable for various communication products, electronic instruments, meters, computers, digital products, household appliances, electric toys, various types of movements, and other precision mechanisms. Of course, they are also used in mechanical equipment, hydraulic engineering, room decoration, ships, vehicles, and other high-tech products mentioned above.

Juxin is a precision screw manufacturer with years of experience in custom production. We can tailor-make screws according to customer requirements, whether it's based on drawings or samples, to provide you with suitable fastening solutions.

Thumb screws are designed for convenient hand-tightening operation, which is convenient and quick. Thumb screws are mainly used in the display industry, white goods, brown goods, telecommunications and data communications, and the automotive industry. The primary material is plastic nylon P66, which has insulation characteristics, is non-magnetic, is corrosion resistant, beautiful, and is not easy to rust. Modified engineering plastics, their use strength, and impact resistance are comparable to metals. We often say that plastic screws are commonly known as nylon screws. After adding 30% glass fiber, its mechanical properties are much higher than ordinary nylon. Diversified materials and broad application fields.

1. Medical equipment industry (insulation, non-magnetic, anti-interference signal, safe use of medical machinery and equipment)

2. Wind power industry (separation and insulation of chassis circuit PCB board)

3. Aerospace industry (insulation on electronic equipment, anti-interference signal)

4. Office equipment industry (not easy to rust, beautiful, and practical)

5. Petrochemical industry (chemical resistance, corrosion resistance, prolonging the service life of the equipment)

6. Electronic industry (insulation, anti-interference, lightweight)

7. Communication industry (insulation, non-magnetic, safety)

8. Ship industry (acid resistance, alkali resistance, corrosion resistance, extended service life)..
