A2 304 is a common grade of stainless steel, often referred to as 18/8. It contains approximately 18% chromium and 8% nickel, providing excellent corrosion resistance, especially against mild atmospheric conditions and many chemicals.
Typically, an M3 hex socket button head bolt requires a 2mm allen wrench (hex key).
Yes, the A2 304 stainless steel construction makes them highly resistant to corrosion, making them suitable for most outdoor applications.
Yes, these M3 bolts are designed to be used with standard M3 metric nuts or with M3 tapped holes.
Button head bolts offer a smooth, rounded, low-profile finish compared to hex or cap screws, and the button head provides a larger bearing surface, which can help distribute load.
Yes, the product description states these are fully threaded bolts, meaning the thread runs all the way up to the head.
The hex socket (or Allen) drive allows for a secure engagement with an Allen wrench, providing better torque transmission for tightening and easier removal compared to slotted or Phillips head screws.
Ensure you are using the correct size allen wrench for an M3 socket. Verify the wrench is not worn or damaged. Use a higher quality wrench for a better fit.
Stop tightening immediately. Ensure you are using the correct size allen wrench and applying firm, consistent pressure. If the head is already stripped, you may need to use a bolt extractor tool.
Check that the bolt is aligned correctly with the pre-drilled hole or tapped thread. Ensure there is no debris in the threads or the receiving hole. Verify you are using the correct M3 thread pitch.
Setup: To install these bolts, you will need an appropriately sized allen wrench (hex key). Ensure the wrench fits snugly into the hex socket to avoid stripping the head. Insert the bolt into the pre-drilled hole and tighten until secure. Do not overtighten, as this can damage the threads or the surrounding material.
Compatibility: These bolts are designed to metric specifications and are compatible with metric nuts and tapped holes. Always ensure the bolt's thread size (M3) and length (10mm) are appropriate for your specific application and the materials being joined.
Care: As A2 304 stainless steel offers excellent corrosion resistance, minimal care is typically required. However, to maintain their appearance and performance, it is recommended to keep them clean and dry. If exposed to harsh chemicals or prolonged saltwater conditions, a gentle wipe-down with a soft cloth may help preserve their finish.
