Forgefix High Tensile Set Screw - M8 x 60 - 10 Pack

'M8' refers to the nominal diameter of the screw's threads, which is 8 millimeters. '60' refers to the length of the screw, which is 60 millimeters.

High tensile steel is a type of steel alloy that has been treated to possess greater strength and resistance to breaking or stretching under high stress compared to standard steel. This makes it suitable for demanding applications.

In many contexts, a 'set screw' traditionally refers to a headless screw used to secure components. However, in some regions or manufacturing terms, a bolt that is fully threaded along its entire shank, often with a hex head, is also referred to as a set screw or set bolt. This product fits the latter description.

Zinc plating provides a protective layer over the steel, acting as a sacrificial coating that corrodes before the underlying steel. This significantly enhances the screw's resistance to rust and corrosion, extending its lifespan, especially in outdoor or damp environments.

While high tensile screws are durable, it's generally recommended to replace fasteners in critical applications, especially after they've been subjected to high stress or corrosion. For non-critical uses, inspect for thread damage, stretching, or head wear before reusing.

You will typically need a 13mm spanner or socket wrench to tighten or loosen the hex head of this M8 screw. Ensure your tools are in good condition to prevent stripping the head.

Ensure you are using the correct size socket or spanner. Apply even, consistent pressure. If the head is already damaged, use a screw extractor tool.

This indicates stripped threads in the receiving material or nut. Replace the nut or re-tap the hole to a larger size if possible, then use a larger diameter screw or a thread repair kit.

This often means the screw was overtightened or the material was improperly prepared (e.g., pilot hole too small). Ensure proper torque, use the correct pilot hole size, and avoid excessive force. Replace the broken screw.

Check if the pilot hole is correctly sized for an M8 screw. Ensure the threads are clean and undamaged. A small amount of lubricant on the threads can also help ease insertion.
