These M4x16mm hex socket button head bolts are designed for professionals and DIY enthusiasts needing reliable fasteners for machinery, automotive, construction, and general projects. Their key benefit is superior durability and corrosion resistance due to A2 304 stainless steel construction, ensuring longevity in demanding environments. A potential caveat is their specific size, requiring appropriate tooling for installation and removal.

You will typically need a 3mm Allen wrench (hex key) for M4 size bolts.
Yes, the A2 304 stainless steel construction provides excellent resistance to corrosion, making them suitable for most outdoor applications.
While strong, these bolts are generally recommended for general fastening and component securing rather than primary structural load-bearing applications, depending on the specific engineering requirements.
ISO 7380 is an international standard that specifies the dimensions and properties for button head socket screws, ensuring consistency and quality.
Clean with a soft, damp cloth. Avoid abrasive cleaners. Regular inspection is recommended.
A2 stainless steel (like 304) is suitable for general use, including marine environments. A4 stainless steel (like 316) has added molybdenum for superior resistance to pitting and corrosion, especially in chloride-rich environments.
Ensure you are using the correct M4 size and that the receiving thread is clean and undamaged. Check for cross-threading.
Verify you are using the correct size Allen wrench. Ensure the socket is clear of debris. The bolt may be damaged if the socket is stripped.
A2 304 stainless steel is highly resistant but not entirely immune. Clean the bolt thoroughly and ensure it is not in constant contact with highly corrosive materials. Inspect for damage to the protective layer.
Setup: To install these bolts, ensure you have a compatible metric Allen wrench (hex key) of the correct size (typically 3mm for M4 bolts). Insert the bolt into the pre-drilled hole and tighten until secure. Do not overtighten, as this can strip the threads or damage the material being fastened.
Compatibility: These M4x16mm bolts are designed to fit standard M4 threaded holes or nuts. They are compatible with materials that can accept a 4mm diameter screw and a 16mm thread length. Ensure your project requires this specific size and thread pitch.
Care: To maintain the integrity and appearance of the stainless steel, clean the bolts with a soft, damp cloth. Avoid abrasive cleaners or tools that could scratch the surface. While A2 304 stainless steel offers excellent corrosion resistance, prolonged exposure to highly corrosive substances (like strong acids or saltwater) may eventually affect the material. Regular inspection for any signs of wear or damage is recommended.
