Document Overview

This technical document provides comprehensive specifications, ordering details, and performance data for a range of standardized mechanical components including shoulder screws, compression springs (FIBROFLEX®), set screws, guide sleeves and pins, round and hollow round bars, and tubular springs. It serves as a reference for engineers and procurement specialists to select and order parts with precise dimensional and mechanical requirements.

1. Standardized Components and Dimensions

Components are categorized by color codes (Green, Blue, Red, Yellow) and detailed dimensional parameters are provided. Key dimensions include:

• Diameter (d1): 6 to 24 mm
• Thread sizes (d2): M5 to M20
• Additional diameters (d3): 10 to 36 mm
• Height (h): 4.5 to 16 mm
• Thickness (s): 3 to 12 mm
• Lengths (l1, l2): Variable by part and size

These dimensions define physical sizes and tolerances essential for compatibility and performance.

2. Ordering Information

Each component size is linked to a unique order number (Bestell-Nr./Order No), facilitating accurate procurement. The document lists order numbers for shoulder screws, springs, rods, and other parts across a broad size range.

3. Tightening Torque Recommendations

Recommended tightening torques are specified in Newton-meters (Nm), ranging from 7 Nm for smaller screws up to 500 Nm for larger components. Adhering to these values ensures proper assembly and prevents damage or insufficient fastening.

4. Shoulder Screws and High-Performance Compression Springs (FIBROFLEX®)

Specifications include thread sizes from M12x1.5 to M42x1.5, lengths, thicknesses, and spring diameters. Corresponding order numbers are provided for each variant, supporting precise selection.

5. Set Screws

Set screws are detailed with dimensional data and order numbers, enabling their use in securing mechanical assemblies.

6. Guide Sleeves and Guide Pins

Two color-coded categories (Violet and White) are presented with detailed tables listing diameters, lengths, order numbers, and spring rates (force per unit deflection). Spring rates vary widely, from approximately 1.1 to 952 units, reflecting different stiffness levels suitable for various applications.

7. Round and Hollow Round Bars

Order numbers for solid round rods and hollow round sections are provided by diameter and length, supporting selection of raw materials or components for assemblies.

8. Tubular Springs

Extensive listings include diameters, lengths, order numbers, and spring rates. Custom diameters and lengths are available upon request, allowing tailored mechanical solutions.

Critical Information and Best Practices

• Use specified tightening torque values to avoid damage or insufficient fastening.
• Select springs and screws based on detailed dimensional and performance data to ensure compatibility and functionality.
• Order numbers correspond precisely to component sizes, facilitating accurate procurement.
• Customization options are available for non-standard diameters and lengths.
• Consider spring rate requirements carefully in design to ensure proper mechanical performance.
