Frequently Asked Questions
What are the manufacturing standards for these hexagon head screws?
Our hexagon head screws are manufactured according to global industry standards including DIN 933, ANSI B18.2.1, ISO, JIS, and AISI to ensure compatibility and reliability.
Which materials are available for the M3-M33 screws?
We provide three main material options: 304 Stainless Steel (304SS), 316 Stainless Steel (316SS) for higher corrosion resistance, and high-strength Carbon Steel.
What is the difference between DIN 933 and ANSI B18.2.1?
DIN 933 is a metric standard for fully threaded hexagon head screws, while ANSI B18.2.1 is the American standard for inch-series or specific metric hex bolts and screws.
Are these screws suitable for marine environments?
Yes, we recommend our 316SS (Stainless Steel) hexagon head screws for marine or chemical environments due to their superior resistance to pitting and corrosion.
Can I get custom sizes beyond the M3-M33 range?
While our standard range covers M3 to M33, these are the most common industrial sizes. Please refer to the material specifications for specialized application needs.
Do these hexagon head screws come fully threaded?
As per the DIN 933 standard, these hexagon head screws are generally fully threaded. For partially threaded requirements, please check the corresponding ISO or ANSI variants.
