STAUFF Hexagon Head Bolt (Type AS – Standard Series)
STAUFF Hexagon Head Bolts (Type AS – Standard Series) are fastening components designed exclusively for use in combination with the Type DP cover plate. Manufactured in accordance with DIN 931/933 or ANSI/ASME B18.2.1, they are available with ISO metric or Unified Coarse (UNC) threads. They are available in zinc/nickel-plated carbon steel (W3) and V2A (W4) or V4A (W5) stainless steel, ensuring maximum dimensional precision for STAUFF Groups 1 to 8. The available product codes, referring to the complete family of standard W3 options listed in the catalogue, are: AS-M6x30-W3, AS1-/4-20UNCx1-1/4-W3, AS-M6x35-W3, AS1-/4-20UNCx1-3/8-W3, AS-M6x40-W3, AS1-/4-20UNCx1-1/2-W3, AS-M6x45-W3, AS1-/4-20UNCx1-7/8-W3, AS-M6x60-W3, AS1-/4-20UNCx2-3/8-W3, AS-M6x70-W3, AS1-/4-20UNCx2-3/4-W3, AS-M6x100-W3, AS1-/4-20UNCx4-W3, AS-M6x125-W3, AS1-/4-20UNCx4-7/8-W3.
The STAUFF Hexagon Head Bolts (Type AS – Standard Series) are essential structural fastening elements within pipework anchoring systems. These bolts are designed in strict accordance with the highest international industry standards. In particular, their construction profile and manufacturing tolerances comply precisely with DIN 931 and DIN 933, as well as the American ANSI/ASME B18.2.1 technical specification. Full compliance with these standards ensures high mechanical reliability. It is important to specify that the engineering dimensions and tolerances indicated for this product family are applicable and certified exclusively when the bolts are used in direct combination with the Type DP Cover Plate for the Standard Series.
To cover the full range of hydraulic and industrial applications, all threaded components in the AS series are available with two dimensional options. Users can select the standard ISO metric thread or the Unified Coarse (UNC) thread. The dimensional range is designed to fully support STAUFF Groups 1 to 8, corresponding to DIN Groups 0 to 8. Specifically, metric lengths range from a minimum of M6x30 for STAUFF Groups 1 and 1A to a maximum of M6x125 for STAUFF Group 8. Likewise, the corresponding UNC variants range from 1/4-20 UNC x 1-1/4 to 1/4-20 UNC x 4-7/8, ensuring compatibility with both European and Anglo-American systems.
The fastening performance and corrosion resistance of the bolts are ensured through a rigorous selection of materials, identified by precise classification codes:
