This guide is for professionals and DIY enthusiasts needing reliable fasteners. The key benefit is the superior durability and corrosion resistance offered by A2 304 stainless steel, ensuring longevity in demanding applications. A potential caveat is the specific ISO 7380 standard, which might limit compatibility with non-standard fittings. These fully threaded bolts feature a hex socket for easy installation and are designed to meet ISO 7380 standards, making them suitable for machinery, automotive, construction, and various DIY projects.

A2 304 is a grade of stainless steel, often referred to as '18/8' (18% chromium, 8% nickel). It offers good corrosion resistance and is suitable for a wide range of general-purpose applications.
For an M3 hex socket button head bolt, you will typically need a 2.5mm Allen wrench.
Yes, the A2 304 stainless steel construction provides excellent corrosion resistance, making them suitable for many outdoor applications.
ISO 7380 is an international standard that specifies the dimensions and properties for button head (also known as low head cap) screws with a hex socket drive.
While they offer good strength for their size, they are generally intended for component fastening, machinery, automotive, and construction tasks rather than heavy structural load-bearing applications. Always consult engineering specifications for critical structural uses.
A2 304 stainless steel is typically non-magnetic in its annealed state, but may exhibit slight magnetism after cold working processes like thread rolling.
The 'M3' refers to the metric thread diameter (3mm), and '16mm' refers to the length of the bolt shank. Other sizes like M5X40mm indicate a 5mm diameter and a 40mm length, offering different strength and reach capabilities.
Ensure the bolt is aligned correctly with the pre-tapped hole or nut. Check for any debris or cross-threading in the receiving thread. Verify you are using the correct M3 thread size.
Use a high-quality Allen wrench of the correct size (e.g., 2.5mm for M3 bolts). Apply steady, even torque. Do not overtighten, especially in softer materials.
A2 304 stainless steel offers excellent resistance, but is not completely immune in extreme marine or chemical environments. Clean the affected area with a stainless steel cleaner. For prolonged exposure, consider specialized alloys if standard stainless steel proves insufficient.
Setup: These bolts require a compatible M3 hex socket (Allen wrench) for installation. Ensure the mating hole or nut is tapped or sized correctly for an M3 thread. For best results, clean the threads of both the bolt and the receiving component before assembly.
Compatibility: These bolts are manufactured to ISO 7380 standards and are fully threaded with an M3 metric thread. They are compatible with any M3 nuts or pre-tapped holes conforming to standard metric dimensions. They are best suited for applications within their specified material and environmental capabilities. They are not designed for extreme temperatures or highly aggressive chemical environments beyond the typical capabilities of A2 304 stainless steel.
Care: Minimal care is required due to the stainless steel construction. However, to maintain optimal performance and appearance, periodically inspect for any signs of damage or contamination. If cleaning is necessary, use a mild detergent and a soft cloth. Avoid abrasive cleaners or tools that could scratch the surface.
