Technical Specifications and Dimensions of Fasteners

1. Dimensional Tolerances

The document lists incremental tolerance values for measurements, with positive increments of +0 and +0.1 and negative increments ranging from -0.10 to -0.20, with some values reaching -0.15. These tolerances likely apply to the dimensions of fastener components.

2. Diameter and Length Availability

A table indicates the availability of fastener bodies by diameter (Ø) and length in millimeters. Diameters range from 2 mm to 10 mm, with lengths available for each diameter marked by an 'X'. For example, 2 mm diameter fasteners are available in lengths 3, 4, 5, 6, 8, 10, 12, and 15 mm, while 10 mm diameter fasteners are available in fewer lengths.

3. Head Types and Standards

The document references several head types for fasteners, each associated with a French standard (NF):

• Round head - NF 27153
• Countersunk head - NF 27154
• Mushroom head - NF 27152
• Flat head - NF 27151

Each head type is accompanied by dimensional parameters such as height (H) and diameter (Ø), with specific measurements provided (e.g., 5 mm diameter with 1.25 mm height for flat heads).

4. Standard Lengths and Customization

The document notes that standard lengths are usually available, but other lengths can be provided on demand, indicating flexibility in manufacturing or supply.

5. Contact Information

Manufacturer or supplier contact details are provided, including address in Epinay sous Senart, France, and telephone/fax numbers.
