'Grade 88' refers to the bolt's material strength. It indicates a minimum tensile strength of 880 MPa (megapascals), signifying a high-strength bolt suitable for demanding applications.
DIN 933 is a German standard that specifies the dimensions and properties for hex head bolts with a metric coarse thread. It ensures consistency and interchangeability with compatible hardware.
Yes, the zinc plating provides good protection against corrosion, making them suitable for outdoor use. However, for very harsh or coastal environments, additional protective measures might be beneficial over time.
For a 10mm diameter hex bolt head according to DIN 933, you will typically need a 17mm wrench or socket.
Yes, their Grade 88 rating makes them appropriate for many structural applications where high tensile strength is required, provided they are used in conjunction with suitable materials and appropriate engineering design.
Store them in their original packaging or in a dry environment to prevent premature corrosion or damage to the zinc plating. Avoid storing them in areas with high humidity or exposure to chemicals.
Check for damaged threads on the bolt or in the receiving hole/nut. Ensure you are using the correct M10 x 1.5 thread pitch and that the hole is clean.
Ensure you are using the correct size socket or wrench (likely 17mm). Apply steady, even pressure. If the head is already damaged, you may need to use a bolt extractor.
While zinc-plated, prolonged exposure to harsh conditions can degrade the plating. Clean the bolt and consider applying a rust inhibitor or a more robust protective coating if the environment is severe.
Verify that the bolt is the correct length and diameter for the application. Ensure the mating material and nut (if used) are of sufficient strength and that the bolt has been tightened to the correct torque specification.
Setup: To install these bolts, you will need a compatible metric socket or wrench set (typically 17mm for a 10mm hex bolt head). Ensure the mating hole or nut is clean and free of debris. Thread the bolt in by hand first to avoid cross-threading, then tighten with your wrench to the appropriate torque specification for the material being joined. Do not overtighten, as this can damage the threads or the material.
Compatibility: These bolts conform to DIN 933 standards, meaning they are designed to work with standard M10 nuts and tapped holes with a 1.5mm thread pitch. Always verify the thread size and pitch of your existing hardware before attempting to use these bolts.
Care: While the zinc plating offers good corrosion resistance, regular inspection is recommended for critical applications. Clean the bolts with a dry or slightly damp cloth if they become dirty. Avoid using abrasive cleaners or tools that could scratch the plating. For prolonged exposure to harsh environments, consider applying a protective lubricant or sealant.
