A2 stainless steel is equivalent to stainless grade 304, which is generally fairly resistant to rusting, but not as resistant as 316 grade (A4 stainless). 316 is used significantly in food preparation areas, for example, where surfaces are substantially wet and / or exposed to aggressive cleaning regimes. If they're going to be installed near the sea, or used in an application that would expose them to an aggressive atmosphere, then they will suffer from a minimum of discolouration, and possibly some light surface rust. I have seen 304 grade stainless steel degrade both badly and very quickly in the presence of an atmosphere with an elevated chlorine vapour, so the full answer isn't simply yes or no. If they'll be miles from the sea, then under normal ambient conditions they should retain their appearance for a significant period. Regardless, I would expect that they will not suffer from the same degradation as other (e.g. BZP) fixings. Hope this helps. **Q: Is there M6 bolts with bigger heads? Best wishes** A: Not normally as they are made to standards and all Cap screws normally have 10mm dia heads **Q: Can you get M6 bolts with larger heads? Best wishes** A: Not a standard. Manufacturers often get specials made for particular products which are available as spares from those manufacturers. Large button heads for motorcycle plastic fairings springs to mind. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality *by on Reviewed in the United Kingdom 18 May 2026* Look to be good quality and came well packaged ### ⭐⭐⭐⭐⭐ Choose the right parts *by on Reviewed in the United Kingdom 18 April 2025* This item was perfect for the job I was doing ### ⭐⭐⭐⭐ Screws *by on Reviewed in the United Kingdom 6 June 2025* Decent quality ## Frequently Bought Together - M6 (6mm x 20mm) Button Head Screws Allen Socket Bolts A2 Stainless Steel Screws (Pack of 20) - AMLOOPH M6 Bolts, M6 X 25mm Hex Socket Button Head Machine Bolts/Screws -Fully Threaded A2 304 Stainless Steel Hex Long Socket Screws M6 (Pack Of 20) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/220637915-m6-6mm-x-20mm-button-head-screws-allen-socket-bolts](https://www.desertcart.ph/products/220637915-m6-6mm-x-20mm-button-head-screws-allen-socket-bolts) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-11-04*
