TIMco Socket Screws & Hex Nuts - Button - Silver

A2 stainless steel, also known as 304 grade, is a common type of stainless steel that offers good corrosion resistance, particularly against atmospheric conditions and many organic and inorganic chemicals. It's suitable for most general-purpose applications, including outdoor use.

You will need an internal hex (Allen) key. For M6 socket screws, a 5mm Allen key is typically required.

These screws are designed for general fastening. For critical structural applications, consult engineering specifications and consider screws specifically rated for structural loads.

The curved button head provides a smooth, low-profile finish that is less likely to snag objects, and it also protects the surface of the material it is fastening against damage from the screw head.

Yes, these socket screws are supplied with matching M6 hex nuts.

Conformance to ISO 7380 indicates that the screws meet international standards for button head socket screws, ensuring consistency in dimensions and quality.

A2 stainless steel offers good resistance to corrosion, making it suitable for many outdoor and some mild marine environments. For highly aggressive saltwater conditions, higher grades like A4 (316) stainless steel might be more appropriate.

Ensure you are using the correct size internal hex (Allen) key. Check that the M6 thread is not cross-threaded or damaged in the receiving hole or nut.

Verify that the hole is properly tapped or drilled to the correct M6 size and that the thread alignment is correct. Check for any debris in the thread path.

While A2 stainless steel offers superior corrosion resistance, extreme conditions can still cause minor surface discoloration. Clean with a soft cloth. If significant corrosion occurs, it may indicate prolonged exposure to harsh chemicals or galvanic corrosion, and the material may need to be re-evaluated for the specific application.
