High Strength Stepped Shoulder Metal Bolt In M10 M12 M16 Custom Shoulder Screws

High Strength Step Bolts in Alloy Carbon Steel Stainless Steel Available in M10 M12 M16 Sizes

Shoulder bolts, or shoulder screws, are fasteners that provide stable spacing, smooth sliding, and rotational movement across various industries. Some common uses include:

• Machinery: Critical for ensuring precise alignment and movement in sliding components within transmission systems.
• Automotive: Used in suspension, engine, and brake systems to connect bushings and bearings, enabling smooth rotation and movement.
• Electronics: Helps maintain precise spacing between circuit boards and chips, minimizing electrical interference.
• Mold Manufacturing: Provides smooth sliding in guiding mechanisms, enhancing precision and prolonging the life of mold components.
• Furniture Hardware: Applied in hinges and sliding rails for controlled movement, boosting durability and functionality.
• Aerospace: Essential for high-precision components where stability and smooth movement are paramount.
• Industrial Automation: Used in robotic systems and conveyor belts to maintain alignment and ensure smooth operation.
• Medical Equipment: Used in adjustable medical devices to provide smooth, controlled movement, ensuring accurate results.
• Tooling & Fixtures: Used in manufacturing jigs to keep components precisely aligned, improving production accuracy.
• Construction & Heavy Equipment: Shoulder bolts help ensure stable movement in structural components, enhancing reliability under heavy loads.

Basic knowledge of stainless steel:

Stainless steel is an alloy material with corrosion resistance, and its main components are an alloy of elements such as iron, chromium and nickel. These elements can effectively resist oxidation and corrosion, so that stainless steel has a high degree of durability and aesthetics.

Maintenance methods:

• Cleaning: Keep stainless steel products clean using mild detergents and soft cloth. Avoid acidic and alkaline components to prevent surface damage.
• Stain removal: For stubborn dirt, use special stainless steel stain remover following product instructions. Alcohol or vinegar can also be effective cleaners.

201, 304, 316 are austenitic stainless steel, according to the performance of the non-magnetic, some of the performance of the weak magnetic because of the smelting of the composition of the segregation or improper heat treatment leads to the austenite in a small amount of martensite or ferrite. Austenitic stainless steel corrosion resistance comes from the formation of chromium oxide protective layer on the metal surface.

304 stainless steel is a general-purpose stainless steel that is widely used to make equipment and machine parts that require good all-round performance (corrosion resistance and formability). To maintain corrosion resistance, the steel must contain more than 18% chromium and more than 8% nickel content.

The Difference Between Full-Thread and Half-Thread Screws
In the field of fasteners and connectors, threads are a common structural form used to provide secure connections or transmission functions. Depending on the extent of thread coverage, threads can be categorised into two types: full-thread and half-thread. This article will detail the distinctions between full-thread and half-thread screws.
I. Definitions and Visual Characteristics
Full-thread screw:

Definition: A full-threaded screw features continuous threads along the entire length of the bolt (or screw).
Appearance Characteristics: Threads are present from the head to the tail across the entire shank, with no smooth, unthreaded sections.
Partial-Threaded Screw:

Definition: Partial-thread refers to a bolt (or screw) where threads are present only over a portion of its length, with the remainder being a smooth shaft.
Appearance Characteristics: Typically, partial-thread fasteners feature a smooth, unthreaded section near the head, while another section closer to the tail end carries the threading.
