Black Carbon Steel Shoulder Metal Bolts Phillips Slotted Curly Shoulder Bolts In 1/6 8/12 1

A shoulder bolt, also referred to as a shoulder screw or stripper bolt, is a specialized fastener designed for applications requiring precision, alignment, and controlled movement. Its unique design makes it a critical component in machinery, automation, and mechanical systems.

A shoulder bolt is characterized by its three-part structure:

• Head: Designed for tool engagement (hex head or socket head) for easy installation
• Shoulder: Smooth, cylindrical shank with precise diameter for bearing surface or spacing
• Threaded End: Smaller-diameter threaded section for secure fastening

The shoulder's length and diameter can be customized to meet specific mechanical requirements.

• Machinery: Precision alignment in transmission systems
• Automotive: Suspension systems, engines, and brakes
• Electronics: Circuit board spacing
• Mold Manufacturing: Guiding parts within molds
• Aerospace: High precision positioning components
• Industrial Automation: Robotic arms and conveyor systems
• Medical Equipment: Adjustable devices
• Construction: Structural components under heavy loads

• Shoulder must fit snugly into its bore to prevent misalignment
• Thread engagement length should match tapped hole depth
• Lubrication recommended for high-rotation applications

Carbon steel offers excellent wear resistance, strength, and cost-effectiveness. Its recyclability makes it environmentally friendly, while its availability and weldability ensure wide applicability across industries.

304 stainless steel is a general-purpose grade containing more than 18% chromium and 8% nickel, widely used for equipment requiring good corrosion resistance and formability.
