FAQs
What does 'A2 Stainless Steel' mean?
A2 Stainless Steel, also known as 304 grade, is a common type of stainless steel that offers good resistance to corrosion and is suitable for a wide range of applications, including outdoor use.
Can these screws be used for flush mounting?
No, these are cap socket screws designed with a protruding head. They are not intended for applications requiring a flush finish.
What size Allen key is needed?
For M6 socket head cap screws, an internal hex (Allen) key of 5mm is typically required.
Are nuts always included?
Yes, this specific product variant (M6 x 16) is supplied with matching nuts.
How many screws are in a pack?
Each pack contains 8 pieces, which includes 8 screws and 8 matching nuts.
Can I use these outdoors?
Yes, the A2 Stainless Steel construction makes them highly suitable for external applications due to their superior corrosion resistance.
What does 'Conforms to ISO 4762' signify?
This means the screws meet the specifications set by the International Organization for Standardization for socket head cap screws, ensuring a certain level of quality and interchangeability.
Troubleshooting
Screw does not thread smoothly
Check that the mating hole is clean and clear of debris. Ensure you are using an M6 nut or a correctly tapped M6 thread. Do not force the screw.
Internal hex drive feels worn or stripped
Use the correct size Allen key (typically 5mm for M6) and apply steady, straight pressure. If the drive is already stripped, the screw may need to be removed using specialized tools or cut off.
Corrosion observed on the screw surface
Although made of A2 Stainless Steel, extreme environments can still cause minor surface staining. Clean with a soft cloth. For severe corrosion, consider a higher grade of stainless steel or protective coatings if environment is exceptionally aggressive.
Pros and Cons
Pros
Superior corrosion resistance due to A2 Stainless Steel
Durable and reliable for external applications
Clean aesthetic with protruding head design
Internal hex drive allows for high torque application
Includes matching nuts for convenience
Meets ISO standards for quality assurance
Cons
Head is designed to protrude, not for flush mounting
Requires an internal hex (Allen) key for installation
Specific M6 size limits immediate compatibility with other thread sizes
Best suited for specific applications where head protrusion is desired
Setup, Compatibility & Care
Setup:
Ensure the mating material has a suitable hole for an M6 thread, or can accommodate a clearance hole if using the nut.
Insert the M6 x 16mm screw through the components.
If using the included nut, place it onto the screw thread.
Tighten the screw using an appropriate internal hex (Allen) key. The size required is typically 5mm for M6 socket head cap screws.
Compatibility:
Compatible with standard M6 nuts and M6 tapped holes.
Ideal for use with materials that are also corrosion-resistant, such as stainless steel or certain plastics.
Requires an internal hex (Allen) key of the appropriate size (typically 5mm for M6).
Care:
While A2 Stainless Steel offers excellent corrosion resistance, regular inspection is recommended in extremely harsh environments.
Clean with a damp cloth if necessary. Avoid abrasive cleaners that could damage the finish.
Ensure threads remain free from debris for easy assembly and disassembly.
