1. Specification Drawings and Dimensional Data

The document provides detailed dimensional specifications for the HUCK® C6L series fasteners, covering nominal diameters of 6, 8, 10, and 12 mm. It includes grip lengths ranging from 2 mm to 32 mm, with minimum and maximum hole sizes specified for each diameter. Key dimensional parameters labeled A, B, C, D, E, and F are given in millimeters, critical for ensuring proper fit and installation. Data is tabulated for two main head styles—B and T—applicable across all materials.

2. Head Styles and Material Compatibility

Two head styles are detailed:

• B Head Style: Dimensions provided for all materials with nominal diameters 6 to 12 mm.
• T Head Style: Similar applicability with slight dimensional variations, especially in parameter D.

All fasteners are compatible with all materials, indicating broad application versatility without material-specific restrictions.

3. Dimensional Trends and Usage Notes

• Dimensional parameters B, C, and F increase proportionally with grip length to accommodate different material thicknesses.
• Hole sizes are tightly controlled with specified minimum and maximum values to ensure proper fit and function.
• Dimensional data supports selecting appropriate fastener sizes based on material thickness and application requirements.

4. Mechanical Performance Data

The document includes mechanical strength metrics such as shear strength, tensile strength (bare, plated, bright dip), clamp force, pin retention, and clamp retention. Values are provided in Newtons and kiloNewtons for various fastener models (e.g., C6LB-R6, C6LB-R8, C6LB-R10). Some data fields are zero or unavailable, indicating non-applicability or lack of test data. Maximum and minimum values for clamp force and pin retention are critical for assessing fastener reliability under operational stresses.

5. Grip Range and Collar Types

Grip lengths vary widely, with minimum and maximum grip ranges specified. The document references LC and 3 LC collars, which are collar types or installation accessories compatible with these fasteners. Collar dimensions and grip ranges are essential for secure fastening and proper load distribution.

6. Installation and Usage Recommendations

• Select nominal diameter and grip length to match material thickness and hole size requirements.
• Verify head style compatibility with installation tools and equipment.
• Adhere strictly to minimum and maximum hole size specifications to maintain performance and safety.
• Use dimensional tables to confirm installation clearances and grip ranges for optimal fastening.
• Consult Huck for guidance on larger diameters, grips, and certain collar types.

7. C Collars Specifications and Strengths

Detailed specifications for C collars include various grip sizes and corresponding minimum strength values. Models such as C6L90-U6, U8, U10, and U12 are listed. Collars are compatible with LC and 3 LC types. Some strength values require manufacturer consultation.

8. Collar Types and Dimensions

Multiple collar types under the C6L family are specified, including 2 LC, 8 LC, and 3 LC variants with different part numbers. Each collar type lists maximum diameter (K Diameter) and maximum length (Max L) in millimeters. Variants include standard, flanged, low profile, and different material codes (R, F, I, 2CU).

9. Product Families and Part Types

The document catalogs product families and part types, including collars and pins with various head styles such as brazier, truss, countersunk, flanged, and button types. Families include C120L, C6L, Magna-Grip, Hucktainer, C50L, HP8, Huck-Fit, Huck-Spin, Magna-Lok, Magna-Bulb, Auto-Bulb, Magna-Tite, Huck-Lok, and FloorTight, each with specific design and application indications.

10. Materials and Coatings

Material codes and coating types are detailed, covering low carbon steel, medium carbon steel, alloy steel, stainless steel, and aluminum alloys (6061, 7075-T6). Coatings include zinc plating with clear or gold chromate, bare finishes, passivation, and black finishes. Standards referenced include ASTM B633, ASTM B695, QQ-Z-235, and MIL-C-81562. Some products have Tab-Lok availability.

11. Nose Assemblies and Tooling Matrix

Nose assemblies compatible with C6L collars combined with LC or 3LC collars are specified by part numbers with dimensional details (A, B, C, D, E in mm). Tooling options include pneumatic, hydraulic, and Powerig tools with model numbers matched to collar diameters and nose assemblies. Hose set options and lengths are also provided, with manufacturer contact recommended for additional lengths.

12. Key Recommendations and Notes

• All strength values are minimum unless otherwise stated.
• Consult Huck for certain strength values, tooling availability, and application guidance.
• Material and coating selection is critical for corrosion resistance and suitability.
• Tooling compatibility details ensure proper installation of collars and pins.

Summary

This document serves as a comprehensive technical reference for the HUCK® C6L series fasteners and associated collars. It provides precise dimensional data, mechanical performance metrics, material and coating specifications, product family classifications, and tooling compatibility information. The detailed tables and part numbers facilitate accurate selection, specification, and installation of fasteners in industrial applications, emphasizing adherence to dimensional tolerances and strength requirements for optimal performance and safety.
