M20 x 120 hexagon head shoulder bolts class 8.8

What are Shoulder Screws with Hexagon Heads?

WDS Shoulder Screws are precision-engineered fasteners designed to offer reliable positioning and connection in applications subjected to transverse forces. These screws are ideal for securely joining workpieces and ensuring their precise alignment, especially in machine and fixture components.

Design Features

• Material: They are made from high-grade steel with a black oxidised finish for enhanced durability and corrosion resistance.
• Grade and Finish: Grade 8.8, offering optimal strength and resilience, with a black oxidised surface to prevent wear and tear in industrial environments.
• Shaft Precision: The shoulder shaft is ground to an outer diameter (OD) tolerance for high-precision fits and concentric to the thread, ensuring a snug and stable fit in components. This precision-ground K7 shaft tolerance is essential for maintaining alignment under load.
• Standards Compliance: These shoulder screws follow a design similar to DIN 609 standards, ensuring compatibility with standard machine components and a reliable fit across various assemblies.

Applications

615 Shoulder Screws are highly suited for applications that require:

• Accurate Positioning: Ideal in applications where workpieces must maintain specific relative positions, especially in machine setups or fixtures.
• High-Load Connections: Designed to handle transverse forces effectively, making them suitable for dynamic environments where lateral stresses are involved.
• Secure and Stable Fastening: These screws provide enhanced stability in assemblies where vibration, movement, or alignment is a concern.

Industries

These shoulder screws are widely used across several industries, including:

• Manufacturing and Assembly: Essential in machine fixtures, assembly stations, and automated machinery that requires consistent alignment.
• Automotive and Aerospace: Reliable in environments where precision fastening and resistance to movement are critical, such as in engine components, brackets, and frame assemblies.
• Industrial Machinery: Often used in machinery that requires frequent disassembly and reassembly, as they ensure alignment and positioning without sacrificing strength.

Product Options

Available in multiple sizes and configurations, the 615 Shoulder Screws accommodate various requirements for diameter, thread size, and length, making them versatile for different setups. Standard diameters range from 9 mm to 25 mm, with metric threads (e.g., M8 to M24) that comply with standard machine fastener specifications.
