Searching for "ISO 7035" typically refers to ISO 7035:1992 (Hexagon Castle Nuts), which covers the dimensions and specifications for these fasteners. If you are looking for a document specifically about "paper" in this context, it is likely a technical data sheet for a product like Palm Cover, which is a specialized recycled fiber paper used for book covers and flexographic printing. ISO 7035 Standard Overview
The official standard for ISO 7035 describes Hexagon Castle Nuts with the following specifications:
Dimensions: Covers product grades A and B, typically for large metric thread sizes (M30 to M100).
Purpose: These nuts are designed to be used with a cotter pin to prevent loosening in high-vibration environments.
Availability: The full PDF of the standard can be purchased from official bodies like ISO or Beuth Verlag. Related "Paper" & Industrial Documents
The term "7035" is also frequently used as a color code (RAL 7035 Light Grey) for industrial paper holders, enclosures, and coatings. iso 7035 pdf
Palm Cover Paper: A technical data sheet is available for Palm Cover, a durable, 100% recycled paper often used as a protective or decorative "covering" material.
Equipment with Paper Roll Holders: Some medical and industrial furniture finished in RAL 7035 (light grey) includes built-in paper roll holders for exam sheets. Technical Data Sheet
The ISO 7035 standard specifies the requirements for hexagon slotted and castle nuts with metric or inch threads. These specialized fasteners are designed to be used with a cotter pin to prevent loosening in high-vibration environments. Technical Overview
Purpose: Used on axles and shafts subject to dynamic loads and vibration.
Design: Features vertical slots (castle slots) where a cotter pin is inserted through a pre-drilled hole in the bolt/axle to lock the nut in place. Searching for "ISO 7035" typically refers to ISO
Strength Classes: Commonly available in classes 4, 5, 8, and 10. Class 8 and above are considered high-strength fasteners.
Equivalent Standards: ISO 7035 is widely considered equivalent to DIN 935. Specifications & Materials
ISO 7035 nuts are manufactured in various materials to suit different industrial needs:
Carbon Steel: Often zinc-plated or galvanized for corrosion resistance.
Stainless Steel: Typically available in A2 and A4 grades for superior chemical and environmental resistance. your quality management system (e.g.
Non-Ferrous Metals: Options include brass and plastic for specific electronic or lightweight applications. Dimension Guidelines
Dimensions vary based on thread size (ranging from M4 to M100). Key parameters defined in technical PDFs include: s: Size across the hexagon flats (wrench size). m: Total height of the nut. de: Diameter of the "crown" or castle portion. n: Width of the slots for the cotter pin. Description Industry Use
Automotive, machine building, furniture, and heavy construction. Typical Range Standard sizes include M4 through M52+. Locking Mechanism Mechanical positive lock using a split pin.
Detailed technical data and dimension tables can be found in reference documents like the Wegertseder ISO 7035 technical guide and the Borenco DIN 935/ISO 7035 datasheet. DIN 935 / ISO 7035 / PN 82148 crown nuts - eurobolt
If your company manufactures hydraulic fittings or uses fluid power components, your quality management system (e.g., ISO 9001) requires you to work with the latest, correct standards. During an audit, you must produce the relevant ISO document. A legally obtained PDF serves as proof of compliance.
Non-mandatory but useful annexes list compatibility of PB, PE, PE-RT with common industrial fluids (acids, alkalis, solvents, oils). This saves hours of separate material compatibility research.
