STAUFF Angled Weld Plate (Type WSP – Standard Series)
The STAUFF Angled Weld Plate (Type WSP – Standard Series) is a fundamental component for the secure fastening of tubing in hydraulic systems, in strict compliance with DIN 3015, Part 1. Available for STAUFF Groups 1 to 6, it offers anchoring options with ISO metric or UNC threads. Manufactured in various material versions, including V2A and V4A stainless steel, it ensures high corrosion resistance and absolute reliability in demanding industrial applications. The available product codes are: WSP-1-M-W1, WSP-1-U-W1, WSP-1A-M-W1, WSP-1A-U-W1, WSP-2-M-W1, WSP-2-U-W1, WSP-3-M-W1, WSP-3-U-W1, WSP-4-M-W1, WSP-4-U-W1, WSP-5-M-W1, WSP-5-U-W1, WSP-6-M-W1, WSP-6-U-W1.
The STAUFF Angled Weld Plate (Type WSP – Standard Series) is an essential fastening solution for the installation and clamping of tubular components in hydraulic and fluid power systems. This component is designed and manufactured in strict compliance with DIN 3015, Part 1, specifically for the Standard Series. Compliance with this standard ensures complete interchangeability and dimensional compatibility with clamps and other accessories from the same series, providing rigid clamping without critical vibrations that could compromise the integrity of the system.
To meet different environmental and operating requirements, WSP angled plates can be configured in various material grades (Material code). The W3 configuration uses Carbon Steel with a zinc/nickel-plated surface treatment, ideal for standard industrial environments and providing basic protection against oxidation. Stainless steel variants are available for applications in aggressive or corrosive environments: code W4 indicates the use of V2A Stainless Steel, corresponding to grades 1.4301 and 1.4305 (AISI 304 / 303). For maximum levels of chemical and marine corrosion resistance, the W5 variant uses V4A Stainless Steel, corresponding to grades 1.4401 and 1.4571 (AISI 316 / 316 Ti). Additional alternative materials and surface finishes are available upon specific request.
The fastening system using the WSP plate features threaded holes designed for anchoring. The coding system includes two main thread variants (Thread code): the letter “M” identifies the ISO Metric thread, typically M6 throughout the Standard Series. Alternatively, the letter “U” denotes the Unified Coarse Thread (UNC), sized at 1/4-20 UNC. The availability of both options facilitates integration into both European-designed systems and systems compliant with North American standards.
The dimensional range covers the entire Standard Series, supporting STAUFF Groups 1 to 6, which correspond to DIN Groups 0 to 6, including the intermediate Group 1A / DIN 1. Geometrically, the plate thickness (S) remains constant at 3 mm for all groups, as do the through-hole height (H) of 6.5 mm and diameters D1 (12 mm) and D2 (6.5 mm). Progressive variations occur in the longitudinal dimensions: dimension L1 starts at 30 mm for Group 1 and reaches 88 mm (3.46 inches) for Group 6. Similarly, the L2 centre distance ranges from 14 mm to 66 mm (2.60 inches), ensuring correct support and load distribution for the different clamp sizes.
