JX-21ZXG142-M6-12-SS, Stainless steel Step standard screws

Standard: ISO7379&GB/T5281, Name: 18-8 Stainless Steel Shoulder Screws

Made from 18-8 stainless steel, these shoulder screws have good chemical resistance and may be mildly magnetic. A standard shoulder with an undersized tolerance allows them to fit most machinery and equipment. They’re often used to guide or align components and as an axle or pivot point. Passivated stainless steel screws have added protection against oxidation and corrosion. Black-oxide stainless steel screws have a matte-black finish.Where are step screws used and their application scope:

1. Screws come in various styles and types, and step screws are no exception. Step screws include Phillips pan head step screws, non-standard step screws, stainless steel step screws, internal hexagon step screws, external hexagon step screws, stainless steel hexagon step screws, etc. Each type of screw has different applications and uses.

2. Step screws refer to non-standard screws with two or more steps, which are commonly known as step screws. Typically, these step screws are not stocked and can only be obtained through mold production. As hardware fasteners that are directly hammered into the workpiece, step screws have the functions of hammering, locking, and fastening. The hardness of step screws also needs to meet the requirements to avoid excessive force during use or the inability of the screw to bend or deform when the workpiece is too hard.

3. Step screws are suitable for various communication products, electronic instruments, meters, computers, digital products, household appliances, kitchen and catering equipment, communication and telecommunication, base station weather, variable pressure instruments, fitness equipment, solar photovoltaic energy equipment, stage lighting, spotlights, energy-saving lamps, aerospace, new energy vehicles, electric toys, various types of movements, and other precision mechanisms. They are also used in machinery equipment, hydraulic engineering, room decoration, ships, and rail transportation vehicles, as well as the high-tech products mentioned above.

Name: Same-Size Thread 18-8 Stainless Steel Shoulder Screws&316 Stainless Steel Shoulder Screws

1. Same-Size Thread 18-8 Stainless Steel Shoulder Screws. With threads the same diameter as the shoulder, these screws can handle heavy loads. Made from 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic. A standard shoulder with an undersized tolerance allows them to fit most machinery and equipment. They’re often used to guide or align components and as an axle or pivot point. Black-oxide stainless steel screws have a matte-black finish.

2. 316 Stainless Steel Shoulder Screws. More corrosion resistant than 18-8 stainless steel shoulder screws, these have excellent resistance to chemicals and salt water. They may be mildly magnetic. A standard shoulder with an undersized tolerance allows them to fit most machinery and equipment. They’re often used to guide or align components and as an axle or pivot point.

Black-oxide stainless steel screws have a matte-black finish.

3. Aluminum Shoulder Screws. One-third the weight of steel, aluminum shoulder screws are lightweight and have good corrosion resistance. A standard shoulder with an undersized tolerance allows them to fit most machinery and equipment. They’re often used to guide or align components and as an axle or pivot point.

4. Titanium Shoulder Screws. Titanium shoulder screws have a high strength-to-weight ratio and are more resistant to acids and salt water than nickel shoulder screws. A standard shoulder with an undersized tolerance allows them to fit most machinery and equipment. They’re often used to guide or align components and as an axle or pivot point.
